I started him on BioJoint supplement powder a couple weeks ago and I'm pleased to say he's already 10 times better.
I had asked my pet store about the products every one recommended but because of the lack of demand, they couldn't keep suppling the stuff I wanted so I got the BioJoint. Kameo is jumping back up to his food with no heistant, wrestling with Crombie again. And for some reason his coat has become softer and shinier since he started taking the powder..
So thanks for all the advice!!
