I tried Canna Pet for my 19 year old cat for the first time last month. I din’t know what to expect but a friend of mine who pet sits for a living recommended it. Gizmo was in a lot of pain from arthritis and also had stomach problems because he has chronic kidney disease. It has done wonders for him. It took about a week to start to see a difference in him but he now eats more and moves so much better than he did. It has helped him tremendously.
