Why does my cat vomit right after eating?

Before explaining why your cat may be vomiting after eating, we need to differentiate between vomiting in cats and regurgitation in cats. Regurgitate in cats involves effortless expulsion, while vomiting involves stronger abdominal movements, neck stretching and emitted sound. Vomiting in cats can be acute, repeated frequently within a short period of time, or chronic, occurring sporadically without remitting for weeks.

Both regurgitation and vomiting require veterinarian consultation. Vomiting in cats causes include; intestinal inflammations, tumors, hairballs, ulcers, foreign bodies and systemic diseases. The possible causes can be detrimental to a feline’s health which is why an accurate diagnosis is necessary. If your cat is vomiting after eating, a veterinarian will likely perform blood tests, an ultrasound and abdominal radio-graphs to find out the cause of the problem.

Why does my cat vomit after eating dry food?

We must first distinguish whether your cat is vomiting up food or hair. Due to a cat’s daily grooming routine, it is normal that it will ingest a lot of hair which will sometimes be expelled through vomiting. A diet rich in fiber, regular brushing and the occasional consumption of malt can prevent hairballs in cats from posing a problem. If your cat is excessively vomiting up hairballs, this could be caused by excessive grooming which is a symptom of stress in cats.

• A cat vomiting up its food hours after eating could be due to obstruction, slow functioning of the digestive system and/or pancreatitis.

Cat vomiting undigested food right after eating: gastrointestinal emptying disorders in cats

Gastrointestinal disease in cats can cause your cat to vomit undigested food long after eating. In some cases, cats suffering from this syndrome will only vomit gastric juice. This is because the cat’s stomach is not able to function at its normal pace. In addition, the cat’s stomach is not able to empty remains correctly, which explains why your cat will vomit after eating.


Gastric retention syndrome in cats can occur due to an injury or a primary or secondary motor disorder. The presence of hairballs can also trigger this syndrome. In addition to finding and treating the cause, you should make sure your vomiting cat is fed a diet rich in fiber, as it facilitates digestion.
