my cat is balemic

i have three cats and my one male cat is balimic. he eats a ton but throws it all up. ive tried to change food and that works for about a month then he starts throwing it up again. i dont know what to do.

Have you tried portioning the food to give him smaller amounts?

What kinds of foods have you tried? Does he throw up every time he eats? And when was the last time he's been to a vet?

Sometimes it can be as harmless as them just eating too fast, so giving the food in smaller portions can help, like LGray said, but sometimes it can be heralding a more serious issue too.

He might just be over eating, my cat will eat whatever you put in the bowl until its gone. we have to portion her food otherwise she throws it all up. remember that dry food expands in the stomach, so if they eat till theyre full without letting it expand, there will be too much once it does, and then theres only one place for it to go

i have 3 cats i give them about 2 cups of food and it lasts about a week. its always out. ive tried taste of the wild and science diet sensetive stomach. hasnt been to the vet in a year. my cats are 15lbs 13lbs and 10lbs. my other cats are fine there is never any blood in it they dont have diarria or anything. they never go outside.

I'd suggest a vet visit. Vomiting could be something more serious than it seems a good vet will be able to (hopefully) rule out the nasty stuff and be able to suggest ideas for the minor stuff.

I agree on going to the vet if this is an ongoing cause. There could be something wrong with his GI tract like a bacteria or it could be a foreign body blockage since he can't hold food down.

I agree with a vet visit as well. Hopefully things get figured out, for you and kitty.

he keeps food down he only throws up once or twice a week.

When mine gets that way it's a sure sign that a hairball will appear shortly. He manages to get one every couple of months, despite hairball medication.
