Spanky was a 16 year old, DSH with behavior concerns and age-related decline in mobility.  He resented some of his housemates and would frequently chase them off or urinate around the house.  Spanky did not respond as desired to multiple therapies, but we finally had a happy cat once Canna Companion was started in 2010.  He was able to tolerate his housemates, had normal urination behavior and could jump onto his favorite perches anytime he wished.  Spanky was the first to let us know that when cats have multiple conditions, sometimes twice daily administration is needed.  We lost Spanky in 2014 due to advancing kidney disease but he will always hold a special place in our hearts.
