She pukes all the time, we've tryed giving her different kinds of cat food, doesnt matter. She also eats grass whenever we let her out.

Cats throw up with such little provication.it's hard to tell.

What is more concerning is that, if she throws up right after she eats, she is not digesting her food..therefore, not getting nutrition. Given that, I would say.time to call the vet. It could be something very simple.but you need to have it checked. quit letting her out so she stops eating grass and see if that helps Take her to the vet maybe she is sick or something.. 1, Have your kitty checked out by a vet.

2. Try Eukanuba Sensitive Stomach cat food.

3. Try Science Diet Sensitive Stomach cat food.

4. Make sure no one is using fertilizer or pesticides on grass the cat eats.

Some cats have grain allergies, and most cat food have grain as their largest (first listed) ingredient .. what had the vet said about this? maybe changing her food all the time is upsetting. and cats eat grass to help them throw up. I'd take that kitty to the vet. She might have wormes or something

I've heard that when they eat grass its supposed to help their stomachs, but who knows, it could be making her worse Having kept lots of cats this can often be the early sign of thyroid problems or sometimes if you give her dry food and she doesn't chew it up it can swell in the stomach and cause vomiting. Does she throw up a lot of un chewed biscuits? Either way, get her to the vet ASAP. It's a cat.
