Overeating is a common reason why cats vomit after they eat. When cats gorge, they overextend their stomach which eventually makes a cat throw up. 

In most cases, cats will keep eating as long as there is food in their bowl. You should therefore reduce the amount of food in the bowl and increase the number of times you feed your cat.

The food will end up mixing with the air causing bloating in the stomach and eventually, the cat will throw up.

c). A new diet

Vomiting in cats can also happen when you are introducing a new diet. The digestive system may be used to digest soft foods before you introduce harder foods which may lead to cats throwing up.

Cats like to keep themselves clean. You will often find them using their tongue to clean their coating. In the process, these pets may end up swallowing a large amount of fur. When the fur gets into the digestive system it forms hairballs.

Hairballs are a threat to the cat’s wellness as they block the intestines interfering with the digestive process. This may result in the cats vomiting to get rid of the hairballs.

In most cases, signs of constipation are displayed with struggle when a cat is pooping. This is because constipation is caused by a lack of water in the digestive system. When a cat is constipated, the entire process of digestion is slowed down. This means that the frequency of cats pooping is slower. This leaves throwing up as an alternative if the cat has to get rid of ingested foods.

Cats may also vomit after eating if they have existing infections related to digestion. These include GI stasis, pancreatitis, and bowel infections.
