Laura, I just saw a commercial on Animal Planet about a product that is supposed to work wonders for animals with arthritis and I thought emediately of Cosmo. Here is the website for the product, maybe it will help him feel better.
Thanks Kathy, that is so sweet of you! I went through the website, there's nothing mentioned about potential side effects, & with Cosmo's liver problems I need to be careful about that. But I'll check w/my vet--she goes for another blood test (hopefully her last test for a long long time) next Friday, so I'll let you know what he says.
