Is dry food really that bad for cats? I've seen a few different vets over the years, and they all had their own opinion on what cats should eat. Most of the vets said good quality dry was best, and canned should be reserved only as a treat. I've had all say that raw was bad for house cats, and not to do it. Though my new vet in this state claims that only canned should be given, but pretty much forbids dry or raw. Though with my last cat, I tried her on canned food for about a month, and it gave her terrible stomach problems and she wouldn't eat much of it and she lost weight. I switched her back to dry, but she always had bad hairball problems (even though she was not a long-haired cat.) I later tried her on Purina Naturals and her coat got shinier, she was shedding less and she never got another hairball. I could never get her to try cat laxes/hairball medicines easily, and even on the occasion that I made her, it never helped. So once I got Finn, I put him on the same thing and he gets tuna as well. He seems very happy and healthy. Is this really unhealthy for him? I've seen so many varying opinions on food, even from vets.
