Why does my cat vomit after eating?

Slowing down mealtime is the most straightforward way to fix this - try using a shallower bowl or spreading the food over a larger surface so he eats more slowly, or even put some obstacles like smooth pebbles in the bowl so he has to work around them. When a cat eats too fast, the food doesn't go down properly and he throws up right after, it's pretty common actually. Another thing that helps a lot is splitting meals into smaller portions spread throughout the day, like 3 or 4 times instead of one or two big meals. If he keeps vomiting even after doing that, then it's worth taking him to the vet to rule out other issues, but in most cases that's all it takes.

Eating too fast is definitely the culprit in most cases - the cat ingests air and excess food, then the stomach can't process it properly and he vomits. What you definitely shouldn't do is switch food or do crazy diets without reason; if it was an allergy or intolerance, he'd vomit regardless of how fast he eats.

The solution is to slow down the meal. Try using a deeper and narrower bowl (like a cup), put just a little food at a time, or if you have a feeder with dividers, even better - it forces the cat to eat in small portions spread out. Some people put a toy ball inside the bowl, but with wet food it gets messy.

Another thing: check if he's actually eating a lot or just eating very fast. Sometimes it seems like he eats a lot because he demolishes everything in seconds. Maybe reducing the amount per meal and offering food two or three times a day instead of just once already does the trick. Give it a month of patience with this, and you'll be able to see if it improves.

Vomiting right after meals in cats is usually linked to mechanical problems, not nutritional ones - and yeah, eating too fast is almost always the culprit. Your cat is taking in a lot of food in a short time, which makes his stomach fill up quickly and he ends up regurgitating without being able to digest properly. Like others have already said, slowing down the meal is the most straightforward solution, but let me add that sometimes you need to test things out for a few days to see what works best with your cat.

Besides spreading the food across a larger plate, you can also try dividing the meal into smaller portions spread throughout the day - lots of cats with this problem improve a lot with two or three smaller meals instead of just one. Another trick that works well is freezing the wet food a bit or adding warm water, which makes the food less dense and forces him to eat more slowly. If after a week or two this doesn't get better or the vomiting looks different (with blood, for example), then it might be worth a vet checkup to rule out other things.

Actually, vomiting after meals isn't as "normal" as it seems - your cat is showing signs that something's wrong with how he's eating. I agree with what others said about speed, but there's another important factor that usually gets overlooked: how much he eats at once. A lot of owners put all the food in the bowl and let the cat eat as much as he wants, which combined with eating too fast results in an overloaded stomach.

Try splitting his meals into smaller portions - two or three bowls throughout the day instead of one big meal. Besides, the suggestion about using a shallower bowl or spreading out the food makes a real difference - it's not just psychological. Wet food in particular makes him gulp it down quickly, so it's worth trying to warm it up slightly (a few minutes out of the fridge) so he can eat more slowly. If the problem still persists after a week or two, it's worth checking with the vet to make sure there's no irritation in his esophagus or stomach.
