My cat is about 14 years old, I think. She pukes almost everyday, and I'm worried about her. I asked the vet, but he's let so many animals die from his lack of knowledge, that I don't trust him when he says it's normal for an old cat to puke a lot. She's on 9lives cat food, made for old cats, and even though she doesn't puke anywhere near as much, she still pukes a lot. I also feed her twice a day like you're supposed to. Is my cat normal or should I be worried?
