I have a female cat who is about 1 1/2 years old. She's been fed well since I got her on Blue canned cat food and canned tuna mixed. She loves it. But a couple of months ago she started vomiting a few hours or more after eating. I took her to the vet and the x-rays just showed she needed to take a good poop. She is wildly playful and doesn't act sick and she is fine after she vomits. I tried stopping the wet food for a couple of days but she won't take to dry food, however this did stop the vomiting. As soon as I give her some wet food she does this again. The pattern seems to be the food. She makes me feel guilty when she wants fed because she doesn't care if I'm sleeping or whatever, she will meow me to no end and keep running to the kitchen wanting food. I don't know what to feed her. The last trip to the vet was $300 plus dollars and I don't think I want to keep spending that kind of money when they don't really do much or say much about it. Can anybody with some experience tell me what to try next?
