Lilies and Cats


Please note a faux lily plant was used for this photograph.

The beginning of Spring just arrived and with it comes a significant hazard for our feline friends: Lilies. While there are plenty of plants which are toxic to cats, we often find that many people are unaware lilies are among them. Beyond that, they don’t just cause simple GI upset like some plants might. Lilies can be deadly to cats.

It is important to know that, for the purposes of this, we are discussing specifically the members of the Lilium family. There are many plants which are called lily without falling into that classification. Some of these, such as the peace lily or calla lily, are still toxic but usually with less severe effects often limited to drooling & GI upset. Others, such as the canna lily or plantain lily (hosta), are non-toxic. 

Pictured below: Lilium (true lily), Peace lily, Calla lily, Canna lily & Plantain lily.


Ingestion of true lilies can cause renal failure in a cat and even result in death; as little as a few grains of pollen have been seen to cause this effect. For many plants, we know the toxic compounds that cause whatever the resulting symptoms are. With lilies, however, the specific substance is unknown. Additionally, many plants only produce toxins in specific parts of the plant; true lilies produce their toxic principle in all parts, from the roots and bulbs to the petals and leaves. This is true even in minuscule amounts. 

Example of true lily belonging to genus Lilium. Not safe for cats.

Should your cat get into true lilies, it is important that you contact your veterinarian or local emergency veterinary hospital and get your pet treated immediately. Lily ingestion is absolutely an emergency and should be treated as such; do not wait until the next morning. If aggressive IV fluids are administered within a few hours of ingestion, the kidneys can sometimes be spared. The combination of an extremely low toxic “dose” and the severity of the resultant toxicity mean that we always advise not having lilies in any household where there are cats, including those which are less or non-toxic.


That’s the best way to keep your feline friends safe.

COA Series: Canna Companion Testing SOP

In our previous articles we discussed the importance of some of the tests that we run during our manufacturing process. Today, we hope to give you a clear view of just how seriously we take your pet’s health by giving you a view of the frequency at which we perform these tests, as well as describing what some of the other tests cover. As always, we want you to feel safe and confident in choosing Canna Companion for your beloved pets. 

There are several stages during our process at which we test our ingredients. For these purposes, the stages we are discussing are as follows: Primary ingredients, Pro-ingredients and Final Products.  We release the COA for our Final Products, but due to proprietary concerns, the Primary and Pro-ingredients COAs are only for internal use. 


Primary Ingredients

This category encompasses all materials in a form which can either be utilized as received or must undergo varying processing modalities before moving into the category of Pro-ingredients. Upon admittance into the facility, primary ingredients are stored in our quarantine area and not released until satisfactory results on the following tests are received. If any material fails any one test, it is never put into production and new ingredients are ordered. Failed ingredients are disposed of per individual requirements. 

  • Residual Solvent Analysis (RSA) – We do not use any primary ingredients manufactured with hydrocarbons, such as butane, naphthalene, hexane, or pentane. We use products derived from CO2 extraction. Ethanol is often used as a wash to remove excess plant waxes, but we ensure the ethanol is either eliminated or well below our medically derived cut-off level in this ingredient category. This is a contractual requirement from our vendors before shipment.
  • Mycotoxin – This is a fungal toxin which develops in improperly stored and handled corn and other crops, and can potentially enter the ingredient chain via contaminated ethanol. Similar to residual solvents, suppliers are contractually obligated to provide mycotoxin levels which are below 20 ppb. This means once a primary ingredient is processed, final mycotoxin levels are even lower or undetectable. 
  • Pesticides – We test for residual pesticides. It is a set panel offered by our certified state laboratory. Only a test result of “ND” (none detected) is acceptable for internal specifications. 
  • Heavy Metals – We have been testing our primary ingredients for heavy metals as soon as our third-party laboratory began offering it (about 1 yr ago). Washington state does not require heavy metal testing on all products, and state certified testing laboratories where slow to adopt as a result. Now that it is offered at our primary certified laboratory, the panel will be run on all product categories.
  • Microbial – We test for the most common pathogens for our patient population, including E. coli & Salmonella as well as for Enterobacter species. E. coli & Salmonella must test negative. Enterobacter concentrations are allowed in trace amounts as standard tests do not differentiate between pathogenic (disease-causing) and non-pathogenic (commensal, non-disease producing) organisms. If concerned, we send a product sample to bacterial identification and proceed from there.  
  • Potency & terpene – These tests determine the overall concentrations of detectable phytocannabinoids and terpenes. We maintain strict ratios between cannabinoids and require terpene contents to remain within specified ranges. Neither test is 100% accurate and some variation is anticipated. That said, we ensure THC levels are <0.3%, individual and total terpene levels are within appropriate physiological ranges (likely to assist the ECS and unlikely to do harm) and all values are consistent with internal calculations. 


These are ingredients that we manufacture in-house. They are made from Primary ingredients and are the products of several multistage processes. These intermediary products, when finished, are ready to be used for final production. At this step, we retest everything as above, making sure a contaminant didn’t get into the production line or that human error is caught before final products are ready for your pet. If any material fails any one of the following tests, follow up tests are performed; if an ingredient fails follow up testing, it is destroyed. All ingredients awaiting test results are kept in quarantine to ensure the production stream remains clean. 

Final Products

These are the finished products, which are sold to clients. At this step, we perform one more round of testing and treat the same as primary and pro ingredients: if it fails initial testing, additional tests are run; if it doesn’t pass, then the product is destroyed. 


What Do These Tests Mean?

As you can see, we take your pet’s safety very seriously, repeating tests at multiple stages to ensure that no contaminants are present to begin with nor are introduced in the manufacturing process. Several of these tests are not required by any regulatory agency. We want to ensure that we provide you with nothing but the very best.

What is it, though, that all of these tests cover? Besides the obvious – making sure ingredients and final products are free of harmful chemicals for your pet – results help us maintain Good Manufacturing Practices. Our employees are proud to hold WA State Food Safety cards, and work hard to ensure a clean and safe manufacturing environment. We share test results with them so they have proof all their efforts pay off. Everyone at Canna Companion is committed to producing high quality products with your pets in mind.   


We hope this gives you a better insight into the precautions that we take in order to ensure that we are providing you with the safest possible product. In the future, we intend to cover what constitutes a true whole plant or full spectrum product versus a single only or near full spectrum product.

COA Series: Potency & Terpenes

Our primary goal, here at Canna Companion, is your pet’s wellness. As you’ve been able to see, we do a lot of testing to ensure everything we make is safe for your furry family member. Along with the many possible contaminants, we also test for potency and terpenes to make sure your pet’s endocannabinoid system will be well supported by our products. In our penultimate article of this series on Certificates of Analysis (COAs), we cover this final set of testing performed on all of our products. As a reminder, the other tests we run include the following:

This last set of tests covers many different compounds. For our purposes, though, we are going to focus on the cannabinoids CBD & THC, and overall terpene content. There are a number of reasons we test for these things; most importantly, we want to ensure that the makeup of our products is appropriate to provide the support that we promise. Knowing the amount of CBD, ratio of CBD to THC, and the terpene content are all important in making sure that our products are aligned with recommended administration guidelines. This way we can demonstrate that your pet’s endocannabinoid system is receiving compounds for optimum support.

Testing for such compounds is not straight forward as there are problems within the cannabis testing industry. While HPLC (high-performance liquid chromatography) is the preferred method for potency & GC (gas-chromatography) ideal for terpenes, significant variation occurs between testing facilities. During our many years in business, we have developed several different ways in which we limit such variation:

  • Routine testing through our primary cannabis testing laboratory
  • Comparison of test results with formulation calculations dating back more than a decade 
  • Quarterly ring tests with secondary and tertiary testing facilities 
  • Retesting of any sample whose initial test results fall outside of standard deviation

In addition to making sure our products remain consistent and within internal specifications, these tests are important to demonstrate regulatory compliance. All of our CBD is derived from hemp, in accordance with federal law. THC content must be below 0.3% and we verify this, maintaining extensive records. You can feel confident knowing that our products are legal in all 50 states. (For more information regarding hemp cultivation legislation, click here.)


In our next article, we’ll be wrapping up this series with information on what tests we perform on which ingredients at different stages during our manufacturing process. We want you to feel completely confident in your choice of Canna Companion. If, at any time, you would like to see a copy of our COA, you may do so by contacting Customer Service.



COA Series: Microbial

Our furry companions make our families whole, so we always want to ensure we’re providing them with the best care available. It can be challenging to analyze whether a product is a good choice, though. Where was it made? What with? How do they ensure safety? That’s why we’re going over Certificates of Analysis (COAs) to show you what information can be found on them. This gives you another tool with which to protect your pet. In this entry in the series, we’ll be discussing microbials. As a reminder, the tests that we do at multiple stages in our manufacturing process are as follows:

Why do we run several sets of tests? It would certainly be less costly to simply test the ingredients, after all. As we’ve discussed previously, current Good Manufacturing Practices (cGMPs) establish baseline standards and ensure that the potential for contamination is minimized. When we test during different stages, this allows us to analyze whether all these practices are working as intended. This also assures you that you’re getting the very best for your animal companion.

The microbes tested for in Canna Companion products belong to the enterobacteriaceae family. These are gram negative bacteria which reside in the intestines of animals and can readily be found within the environment.. Many of them are a part of the normal gut flora of animals, but there are also a number of familiar, disease-causing strains including Escherichia coli and Salmonella

As you are likely aware, these coliform bacteria can cause both gastro-intestinal and extra-intestinal infections in cats, dogs, and people. Most of these are presence/absence tests where any detection in a sample means failure. Because of the potential human health risk, E. coli and Salmonella quantities must remain below detectable levels. Other members of the enterobacteriaceae family are non-pathogenic or low grade opportunistic bacteria. This means they are either not known to cause disease, or may do so under the right circumstances and levels. These bacteria are commonly found within the GI tracts of healthy dogs and cats


The health and wellbeing of your animals is our primary purpose. We want to ensure you have the knowledge and tools to protect them no matter what food or supplement you are considering for them. If you have questions or if there are parts of the industry you would like to know more about, please don’t hesitate to contact us. We may cover your topic in a future post.


Tips to Keep Your Pet Safe During Football Parties

The biggest football game of the year is approaching quickly and perhaps you, like many others are hosting a party to watch the big game. You may be looking forward to friends, food, drinks and football, but your dog, cat or parrot may have a very different perspective when it comes to the festivities. New people, noises and smells can be very exciting, but for some it’s  overwhelming. Pet parents need to be aware there are a few things about a sports event party that are downright dangerous for our pets. Here are a few tips from Canna Companion that will help your pet during the big game.


Cheering and Shouting Plus Pets Don’t Mix – You and your friends love cheering for your team loudly and enthusiastically. Keep in mind that this out of the ordinary sound level and intensity might result in your pet becoming over stressed. Situational anxiety is a real thing for our furry and feathered friends, and it can be scary for your pet and even dangerous for your guests. Some pets might try to hide in or under something, pace, hypersalivate (drool) or in extreme situations try to escape the house unsafely or engage in other harmful behaviors. They may act fearfully, bark, or snap at strangers who try to approach.

The best thing to help your dog through these types of situational anxiety triggers is to be prepared in advance. There are a number of supplements offered by Canna Companion that have a calming effect on the mind when situational anxieties arise. One tip that is assured to help them remain calmer: let your pet have their own space, behind closed doors, with plenty of comforting bedding. Leave soft music on to help distract them from party goer cheers. 


Sporting Event Snack Foods Should be Kept Out of Reach – Some of the common appetizers at a sports event party are potentially dangerous for dogs. If your pet happens to be social, they may prefer to hang with the crowd. However, make sure to keep food off lowered tables and out of your dog’s reach. Advise your guests not to feed your pet, no matter how cute they are or funny things they say.

  •  Chicken wings have harmful bones that can splinter and wreak havoc on a dog or cat’s intestinal tract or get stuck in the throat, causing them to choke. 
  • Onions, garlic, and chives can cause upset digestive systems and damage red blood cells, especially  in cats. Make sure dips are out of reach or kept in covered containers.
  • Salt found on chips and pretzels causes excessive urination and thirst. Most of these snacks are also carbohydrate heavy and inappropriate for dogs and cats
  • Dark chocolate is especially toxic and can cause GI upset and restlessness and death in severe cases.
  • Cheese and other dairy products can lead to upset stomach and diarrhea, as most pets lack the enzymes to break down lactose. If you offer any diary treats, limit it to 1 per party and make the portion size small (~1 tsp).


Watch the Alcohol and Caffeine – Alcohol is toxic for pets. It can cause any number of problems including vomiting, diarrhea, difficulty breathing, tremors, loss of coordination, abnormal blood acidity, coma, or even death. Caffeine from soda, iced tea, or coffee can be just as bad. It can lead to abnormal heart rhythms, seizure, or death. Keep the drinks in hand and away from all pets, and if your dog, cat or bird likes to investigate “empty” cups, best to leave them in their own room until after the party.


Secure Your Trash –  It might make sense to leave a trash bin in an open space so your guests can find it quickly, but if your guests can get to it easily, so can your pet. Getting at the paper plates or plastic cups that have no food on them can cause indigestion, choking or obstruction in the gastrointestinal tract. This can lead to an emergency veterinary visit. So, it’s best to keep the garbage in a secure place and out of reach of your pet. If you do leave the trash can out, make sure it’s a secure one even the craftiest critter cannot get into.


Watch Out for Clumsy Drinkers – There’s nothing wrong with having a few adult beverages. It’s a party, after all. But people who have had a few drinks tend to be a little more touchy-feely, especially if there’s a cute pet running around. The lack of coordination and reduction in motor skills can also lead people to be clumsy, and they might not be able to react in time if a dog suddenly appears in their path. Tripping, stumbling party guests can lead to injuries for pets and humans alike.

Keep an eye on your pets. If your pets seem to be having difficulty settling down or are trying to eat foods available, it may be best to secure them in a different room or kennel, if that is a known safe place for your pet. Contact us for additional tips so you and your friends can enjoy the game, and your pets enjoy some R&R. 


COA Series: Heavy Metals

Every pet parent wants to make sure that they’re providing their companions with the best care possible. In our series about testing protocols and Certificates of Analysis (COAs), we are detailing the many steps we here at Canna Companion take to ensure that our products are safe and free from contamination. In this entry, we’ll be discussing heavy metals, and for your reference, here’s the list of tests run on ingredients and end products.


Heavy Metal Testing

Among the more common heavy metals associated with toxicity are lead, arsenic, mercury, and cadmium. Exposure to these items can occur in a number of ways including air, soil, or water pollution, improperly applied coating on packaging or bowls, and contaminated foods or medicines. Heavy metal poisoning can take place via both acute and long term exposure, and while compounds like inorganic arsenic increasingly rare, exposure can still occur via ashes of treated lumber, for example. Metals like lead cause a variety of health issues include anemia, cancer, and seizures, while mercury exposure results in symptoms ranging from severe GI distress to eczema (in survivors or toxicity) to death. 

All species of the Cannabis genus are classified as phytoremediation plants, which means that they are particularly adept at pulling numerous types of contaminants, including heavy metals, out of the soil and storing them in plant material. Heavy metals persist within the environment, and during the normal processing of hemp plant biomass, these toxins are concentrated. The small size of our patients further exacerbates the hazard as a relatively safe amount to a human, becomes highly toxic in cats and dogs. While there are treatments available for heavy metal poisoning, they can be costly and are not 100% effective.  Thorough testing is an easy and highly accurate way to help prevent the problem in the first place.

While the FDA does provide action levels whereby companies must remain under certain testable levels of heavy metals, this does not include pet supplements.  Washington state does not require testing for heavy metals and, as a result, many of the state certified laboratories have been slow to include it as an option. Since a panel is available via our primary certified lab, we test all primary ingredients and end products for arsenic, cadmium, lead and mercury. We tolerate “None Detected” (ND) quantities of heavy metals in our finished products, and trace or ND in primary ingredients. Because one can never truly have ‘zero’ quantity, laboratories provide results as LOD (limit of detection) relative to LOQ (limit of quantitation). ND results ensure Canna Companion products have so little heavy metal content, it is not detectable with current technology.

COA Series: Pesticides

When shopping for food we’ll often note whether or not something is organically grown knowing that, among other things, this protects us from most pesticides. How many of us do the same when we are selecting items such as lotions, cosmetics, or supplements? When those supplements are for our pets, knowing whether or not they contain pesticides is critical. In this latest entry in our series about the testing that we do and what information you can find on a Certificate of Analysis, we’re discussing pesticides.

As a refresher, we test for the following:


Pesticide Testing

At all stages of our process (primary ingredients, pro-ingredients, and final products) we test for residual pesticides via a set panel performed by a certified state laboratory. Pesticides are obvious toxins, classified by their actions and levels of toxicity at various dosages. They can be introduced into hemp products via farming practices and extractor processes; a contaminated water supply is also a concern as it can allow highly toxic chemicals to travel long distances

This map shows estimated concentrations of atrazine in shallow groundwater beneath agricultural land. Atrazine use is one of the most important factors used to predict atrazine and deethylatrazine concentrations in groundwater (right). Within areas of high atrazine use, groundwater residence time, soil permeability, and other factors explain some of the differences in predicted concentrations. From USGS Circular 1360.


Often people think that if something is naturally derived, it is safer. This is not always the case. Pyrethrins, common pesticides derived from the chrysanthemum, can be extremely dangerous, even deadly to cats. Similarly, organic is not necessarily pesticide-free, though the opposite can be true. And to make it more complicated, no single laboratory can test for all possible pesticides, and one has to rely on regulatory agencies to ensure nothing toxic at low doses leaches through into the environment or test sample. Allowable levels in our and our pets’ water supply may not be safe when orally absorbed in a solid or oil-based liquid. 

If you combine this with the fact that when compounds like CBD are extracted from hemp, any pesticides used on the plant or within the water supply are then concentrated, it becomes very clear why this testing must be performed. A chemical that is safe for adult humans in tiny amounts, then concentrated and given to a child or pet who are much smaller could be extremely hazardous. Many pesticides can exacerbate existing health problems or even cause new ones. They can be carcinogenic, teratogenic, hepatotoxic, neurotoxic, nephrotoxic, and potentially disrupt hormones, the endocrine system, and the immune system. 

Most of the commonly used pesticides in the cannabis industry fall under Category 3, 4, or 5 WHO classification scheme. This means they “may be harmful,” are “harmful,” or are “toxic if swallowed,” based on dosages which caused harm in 50% of rat test subjects (LD50). Many of the chemicals do not have LD50’s for cats, dogs, or even humans. Others have veterinary-based applications and are commonly applied topically (ex. imidacloprid and pyrethrins/pyrethrins) or given orally (ex. spinosad) for flea control.

Because of the potential risk to cats and dogs of all sizes, we test multiple times to ensure that any residual pesticides are below the level we have determined to be safe, typically “none detected” (ND) or in trace amounts. Trace amounts to us means an estimated amount which is greater than the Lower Limit of Detection (LLOD)  but less than the LLOQ. The LLOD is the lowest amount that the method can detect and the LLOQ the lowest amount that the method can quantify. Our reasoning? Such levels are usually secondary to environmental contamination and is one reason we check local water testing results, cross-referencing them with Washington state cannabis testing parameters and our internal specifications.  

We believe in full transparency at Canna Companion and want you satisfied your pet is receiving the very best. You deserve to know what is, and is not, in our products before you give them to your pet. Contact us today for a copy of our batch-tracked Certificates of Analysis!

COA Series: Mycotoxins

Pets are important members of our families and we always want to ensure we’re giving them the very best. There are reviews, consumer reports, and more that we can look at to help us determine these things, but sometimes it’s just not enough information. Other times, that information is presented in a manner that isn’t readily accessible to the layperson. That is why we here at Canna Companion are breaking down the details of what can be found on a Certificate of Analysis and why those tests are important. 

In part two of our Certificate of Analysis (COA) Series, we detail mycotoxin testing. In our last article, we discussed the importance of Residual Solvent Analyses (RSA) in making sure chemical toxins leftover from cannabis compound extract processes are absent or well-below toxic levels for cats and dogs. One of those solvents, which is quite easy to remove from end products, is ethanol. Most ethanol on the market is made from corn, some of which comes from crops contaminated with mycotoxin producing organisms.

Canna Companion values the health of our patients above all else. Throughout this series, we provide insight into our testing procedures which often exceeds federal testing requirements to better protect the welfare of your pet. As a reminder, tests run on ingredients and final products include:


Mycotoxins, like aflatoxin and ochratoxin, are a group of natural, highly toxic byproducts of some Aspergillus and Penicillium fungi. These toxins develop when certain crops are improperly stored at temperature and humidity levels that perpetuate fungal growth. The risk increases with environmental stress to crops such as drought or insect damage, improper field management, and inappropriate handling. Crops known to be affected by fungal contamination include corn, peanuts, rice, soybeans, wheat, and oats. The organisms and their secondary metabolites, mycotoxins, are so ubiquitous that approximately 25% of the world’s food supply is contaminated, causing death in human and non-human animals.

Aflatoxins can be immunosuppressive and carcinogenic, damage the liver, cause anemia, and more, even at extremely low levels. They are fat soluble and easily absorbed from the GI tract of dogs and cats. A little over a decade ago, hundreds of dogs died from liver failure due to eating commercial dry dog food contaminated with aflatoxin.  Ochratoxin is less common, but just as deadly, also causing cancer and usually targeting the kidneys. There is very little which can be done once toxicity occurs, but fortunately a lot which can be done to prevent contamination in the first place. It all starts with testing.  


Why is mycotoxin testing vital?

Ethanol, CO2, and butane/propane are currently the most common extraction solvents utilized in the Cannabis industry. Ethanol is often made by fermenting corn. Mycotoxins, if present, survive the fermentation process. When this mycotoxin-contaminated ethanol is used in the processing of any Cannabis products the mycotoxin is transferred to them.

Unfortunately, most poor-quality, damaged, and improperly stored corn is diverted into ethanol production. While mycotoxins do survive fermentation and distillation processes, they should only be measurable in the solid co-products, not the liquid alcohol. Any ethanol product contaminated with mycotoxin is likely the result of improper distillation, filtration, and cleaning techniques. As a general rule, since human and pet food companies place large orders, they get to choose the quality of corn they purchase. They do not wittingly purchase contaminated grain.  Reputable companies make sure the corn they use meets or exceeds FDA action levels. 

Because mycotoxins are not concentrated in ethanol, it is acceptable to test for them only at the corn harvesting stage. Testing of ethanol is not required by any regulatory agency. Restrictions are, however, placed on acceptable quantities of mycotoxins found in the corn used to make grain alcohols. FDA Action Levels are as follows, based on intended use of the corn.

FDA Action Levels for Aflatoxins

Commodity Level (ppb)
Milk 0.5
All feedstuff other than corn 20
All products, except milk, designated for humans 20
Corn for immature animals & dairy cattle 20
Corn for breeding beef cattle, swine & mature poultry 100
Corn for finishing swine 200
Corn for finishing beef cattle 300
Cottonseed meal (as feed ingredient) 300


Cats and dogs are especially susceptible to the effects of mycotoxins, and while the lethal dose (>300 pbb) is far greater than what is allowed in non-milk products, severe illness can occur with chronic low dose exposure. That susceptibility is, in part, dependent upon factors such as genetics, age, hormonal and nutritional status, and concurrent disease. As a result, if a company making products for cats or dogs utilizes ethanol extracted or washed products in any ingredient, both that ingredient and the final product should be tested for aflta- and ochratoxins.  

To protect the health of your pet, Canna Companion requires all ingredients, pro-ingredients, and finished products have total mycotoxin levels limited to 0-19 ppb. We are medical professionals and understand the adverse medical implications these fungal-based contaminants pose for our patient population. We strive to provide products which are clean and consistent, relying on rigorous testing practices to help fulfill that objective.  

COA Series: Introduction & RSA

As pet parents, we are naturally concerned with ensuring that any product or supplement we give to our pets is safe for them. Often, however, we have very limited access to information about anything beyond the ingredients of a product. While reviewing ingredients is very important, it only gives us a snapshot of what a company does in order to help ensure our pets’ safety and can sometimes leave us wanting more information. To that end, we would like to offer you an idea of what kinds of tests we run during the manufacturing process at Canna Companion and how these help protect your pet. 

We send samples to local, third-party, state-certified, cannabis testing laboratories during multiple stages throughout our processes. Each sample is tested for a variety of chemicals to make sure no toxins are present and that compounds like CBD and THC are within product specifications. In our Certificate of Analysis (COA) Series, we will detail what those tests mean with regard to your pet, beginning with Residual Solvent Analysis (RSA). Our final article in this series reviews Canna Companion testing procedures on all primary and pro-ingredients as well as the final product.

Tests run on ingredients and final products include:

  • Residual Solvent Analysis 
  • Mycotoxin
  • Pesticides
  • Heavy Metals
  • Microbial
  • Potency & Terpenes 


Residual Solvent Analyses detect minute levels of hydrocarbon and non-hydrocarbon solvents used in the extraction processes of a wide variety of Cannabis products. Residual hydrocarbon solvents are potentially damaging to cardiac muscle in trace amounts. They can impart immunosuppressive and abnormal immunostimulatory effects in extremely small concentrations. Some compounds cause hepatic, renal, and neurotoxicity, and should be avoided in any patient population with these underlying pathologies or susceptibilities. Ethanol and its derivatives appear better tolerated, though can still pose health risks at higher quantities.  

Residual solvents are the byproducts of nearly all extraction processes. Even ‘solventless’ extractions, like CO2, can result in residual chemicals lingering in the final product. This is usually due to post-extraction ethanol washes designed to remove plant waxes. Several techniques can be used to remove solvents from end products; the most effective of these is vacuum extraction, set at temperatures specific to the solvent used. RSA are a critical element of cannabis testing simply to ensure any impurities are absent or well-below toxic levels for the intended species. A small amount of these solvents in a product for a human sized patient is probably not harmful and each state sets limits regarding what is acceptable based on their data and risk assessments.  

In our patient population, however, the concentration of these contaminants is important because of the size of the patient exposed. A small amount of solvent concentrated in a smaller patient can more readily impart adverse effects. Furthermore, many of the breakdown metabolites produced by the metabolism of hydrocarbons are toxic as well, meaning they continue to impart toxic effect and can reside in the system for an extended period. Ethanol can be effectively and completely removed from any material on which it is used, with minimal effort, and is better tolerated in trace amounts when compared to other hydrocarbon solvents.


To avoid the potential adverse events from residual hydrocarbons, it is best to only administer pet products which are CO2 and/or ethanol extracted from companies willing to provide batch-associated COA backing their claims.


A Brief History of Cannabis for Pets

Given the ongoing conversations around legalizing medical and recreational marijuana, it might seem like cannabis just leapt onto the scene in the last few years. Suddenly, everyone is talking about the benefits of cannabis, for both people and pets. But the cannabis plant has actually been used to address various conditions for thousands of years. At Canna Companion, we’ve been exploring its place in veterinary science for decades. Today, we’re taking a quick look at the history of cannabis for pets. 

What Do We Mean by “Cannabis?” 

First, let’s make sure we’re all on the same page when it comes to cannabis. A lot of terms get thrown around—cannabis, marijuana, hemp—and misused or conflated. Here at Canna Companion, we’re interested in the benefits of hemp, the type of cannabis plant which cannot produce a “high.”


It’s important to note that the term “cannabis” is also used to refer to marijuana, another type of cannabis plant which can induce euphoria.  We do not recommend giving your pet marijuana products, as they can cause adverse reactions like low blood pressure and confusion. Possession of marijuana is also illegal in much of the country, while hemp is legal in all 50 states. 

Cannabis Use in Pets Over the Years

Before there were hemp-based products created exclusively for pets, people recognized the potential benefits of CBD oil and other supplements containing CBD for both people and animals. Dogs and cats experience similar issues as we do, after all—short-term anxieties, achy older joints, and more. As the reasoning went, if something works for humans, surely it must work for pets. Go back far enough, and you’ll find multiple stories of pet parents securing a medical marijuana license for the sole purpose of purchasing cannabis products for their ailing pets. The issue here was that those largely unregulated products contain varying ratios of CBD to THC, meaning that it’s impossible to predict the effect they might have on a pet. 


A number of studies have confirmed the incredible supportive potential of the various compounds found in the cannabis plant, such as phytocannabinoids, terpenes, and flavonoids. In light of the possible physiological, immunological, and neurological benefits, it became clear that a formula made exclusively for pets was needed. 

Canna Companion Breaks Into Cannabis Science

After observing the benefits of a well-supported endocannabinoid system, we decided to create a hemp-based supplement formulated just for pets—something that could leverage the vast potential of the cannabis plant without the adverse effects that marijuana has on animals. Our research led us to create a high-quality supplement made from the mature stalks and seeds of the Cannabis sativa plant. 


We founded Canna Companion in 2014 with the goal of providing quality hemp supplements for pets and educating pet parents and their veterinarians on the supportive benefits of cannabis. We made sure our formulas support the optimal health of pets, in more ways than one. While single-compound products can throw off the synergistic relationship between chemical compounds, our in-depth research into the endocannabinoid system resulted in “whole plant” products, which preserve the entourage effect and provide comprehensive support to the endocannabinoid system.  

Ongoing Uses of Cannabis for Pets

Although state and federal regulations on cannabis are continuing to shift, hemp-based pet supplements are and will remain legal, provided the company adheres to all relevant regulations, such as any laid down by the FDA or NASC. Veterinarians across the country are now recommending reliable hemp supplements, like hemp-based CBD  oils, to pet parents looking for an additional way to promote their cat or dog’s well-being.


With carefully controlled ratios of CBD to THC, Canna Companion products support the health and happiness of pets while minimizing the adverse reactions associated with marijuana use. 


Here are just a few of the benefits of introducing and regularly administering a hemp supplement for pets:

  • Provides neurological support
  • Promotes a calm demeanor
  • Maintains normal joint health
  • Encourages a healthy GI tract
  • Assists in end of life comfort and care
  • Supports the functioning of the immune system


As with any change to your pet’s supplement routine, be sure to check with your veterinarian before introducing a hemp-based pill or oil. Each animal reacts to hemp-based products differently, so you may find that your pet needs a different dosage than the standard. If you have further questions about whether or not your pet would benefit from a hemp supplement, contact a licensed veterinary professional.

Potential Future Uses of Cannabis for Pets

The future looks promising when it comes to the potential applications of hemp-based pet supplements. As more studies are done, and we continue to advance in our understanding of cannabis science, we look forward to discovering even more about this beneficial plant.


One of the main challenges facing veterinary use of cannabis is the lack of existing industry regulations. Overdoses, incorrect ratios of CBD to THC, and low-quality products can leave pets lethargic and uncoordinated. Fortunately, these effects only last for a few hours, and there are no known long-term effects of hemp usage in pets. Moving forward, Canna Companion will continue to stand out from industry competitors by sticking to our rigorous standards and offering the high-quality hemp supplements we’re known for producing.
