I don't know what my vet sells anymore as far as pet food. It's been awhile since I bought a bag of food from her. I know when my cat was alive, we were feeding him Purina Diabetes Management. It was no carbs or sugars, I think. I want to say she has a different kind of food, now, though. I'll look when I am there for Finn's neuter surgery (hopefully soon). I just happened to be at another vet's cuz I had some questions (they were actually more for a friend of mine). Anyway, he was the one that sold Pro Plan. I mean, he shot that out at me like it was gold. You should feed Purina Pro Plan. I'm like, geez, he must get commission. What does Julia roberts say in Pretty Woman? "Big mistake. Huge."
