Why does my cat keep vomiting?

Question

My cat keeps vomiting every night and i have no clue why. We have not changed his food or anything he eats and he does everything else the same. Nothing has changed. He is 8 years old. He is overweight, but I don't know if that is the problem. He throws up everything he ate or drank that day. He just lays around, but he always has but now he looks sad or sick or something. This has been going on for about a week and a half. He went to the vet they said nothing is wrong but I think there is he has never done this before. So if any one knows anything at all will you please help me out.

Answer 1

I'd go back and get some blood work done.  There's probably an underlying cause.  Some diseases aren't manifest until later in an animal's life.

Answer 2

I have a cat that vomits pretty regularly.  She just eats and eats and eats until she gets sick.

I've tried worming her and it helped for a while but I also have reason to believe that she is diabetic.

You might have your cat screened for it.

Good luck

Answer 3

your cat is probably overeating, especially if your cat is overweight. I would see a vet to put your cat on a diet.

Hello oh poor baby, Please take him to a VET for a blood test, he may have diabetes, or pancreatitis, this is totally not normal.. he is losing valuable fluids not safe..  Sometimes cats can throw up a hair ball but this sounds like something more serious.. better to be safe than sorry!! GOOD LUCK!
