Why Your Cat Vomits Yellow Foamy Liquid

1 Overview

1. Gastroenteritis

Feline gastroenteritis is actually abnormal inflammatory cells accumulating in the cat’s stomach and intestines; these inflammatory cells keep irritating the intestines, destroying normal nutrient absorption. Cat gastroenteritis can be long-term or chronic, but typical symptoms include vomiting, with gastric fluid and bile vomited together. If your cat vomits long-term, treat it promptly to avoid developing into severe inflammatory bowel disease.

2. Intestinal parasites

Intestinal parasites also attack the cat’s intestines, destroying the gut immune system and causing nutritional imbalance. Generally infected cats show vomiting and diarrhea. Owners can find worms or eggs in the vomit or stool; severe cats even vomit blood and have diarrhea. As nutrient absorption drops, the cat becomes thin, dehydrated, with dry coat.

3. Viral infection

Feline distemper (panleukopenia), feline parvo, and feline coronavirus all cause intestinal disease in cats; as the virus spreads in the gut, it destroys the cat’s gut immune system, triggering a series of bacterial infections and inflammation. The most common symptom of these viruses is frequent vomiting, the vomit is generally yellow-fluid-like, sometimes with blood; the diarrhea is unformed, and as the virus spreads the stool becomes tomato-colored watery with a fishy smell.

The above are several common causes of cats vomiting yellow fluid; of course there are other more serious but rarer causes, like nervous system disease and liver-kidney-pancreas disease causing cat vomiting. When owners find a cat vomiting yellow fluid, it is more advised to take the cat to the hospital for diagnosis, for peace of mind.
