Main causes

Normally, vomiting yellow in cats usually indicates the expulsion of bile. This liquid is excreted by the liver and stored in the gallbladder to fulfill its function, aiding indigestion. The digestive tract performs a series of involuntary movements that are known as peristalsis, but when toxins enter the body or it needs to be purged, these movements are reversed and cause vomiting. The most common causes of why a cat vomits yellow are as follows:

  • Prolonged fast.
  • Intestinal parasites.
  • Diseases: colitis and other intestinal inflammations, pancreatitis or liver problems.
  • Poisoning or intoxication.
  • Strange bodies.

Next, we are going to talk in detail about each of these causes that answer your question about “why does my cat vomit yellow foam or yellow liquid?” And we are going to explain what is usually the treatment that the vet applies and what you can do if you see that your cat has this symptom.

Prolonged fasting

The most common and easiest cause to treat is vomiting which is yellow in color due to prolonged fasting. When a cat goes for hours without eating, gastric fluids along with bile accumulate in its body. This content is acidic and inflames and irritates the lining and stomach walls. Given this, the body reacts with vomit to expel this mixture of gastric fluids and bile. In this situation, the only yellowish or somewhat greenish liquid is observed, which contains neither blood nor mucus.

The treatment for this problem is simple and it stops giving him something to eat that is soft, that he can easily digest, and appetizing and, when he returns to eating more normally, he will have to follow a healthy diet, without foods that are not convenient for his health. Even so, before any type of vomiting, it is recommended to go to the vet to rule out possible diseases, but if the vet diagnoses that this is the cause that is causing yellow vomit, it will indicate the diet that your feline needs and if there is an underlying cause it will treat it.

Intestinal parasites

If there is the presence of intestinal parasites in your cat (also known as worms or worms), it will have symptoms such as:

  • Yellow or bile vomiting.
  • Diarrhea.
  • Swollen abdomen.
  • Lethargy.
  • Presence of parasites in feces or diarrhea.

If you have noticed any of the symptoms mentioned, you will have to go to your vet to apply the right type of dewormer to your cat and end the problem. It is important to bring adequate deworming to your kitten partner to avoid this type of problem. Internal deworming is recommended every 5 or 6 months, depending on what your vet tells you.

Related diseases

There are pathological causes for which your cat may be vomiting bile, so you must take it into account to go to the vet as quickly as possible and prevent the problem from worsening. The pathologies by which a cat vomits yellow that turn out to be more common are the following.

Colitis and intestinal inflammations

There are many inflammatory bowel conditions, but one of the most common that can lead to yellow vomiting in cats is colitis or inflammation of the colon. This pathology, if not treated immediately, causes various symptoms, among which are vomiting of bile, diarrhea with blood and whitish mucus and irritated anal area, among others. On the other hand, feline inflammatory bowel disease, which is a group of gastrointestinal conditions, also stands out.

Pancreatitis in cats

This disease consists of inflammation of the feline’s pancreas. Against this, cats are apathetic and do not usually eat, so they perform long periods of fasting. That is why you can see vomiting of bile, diarrhea, bloating and pain in the abdomen, sometimes even fever, anorexia and dehydration. The treatment is symptomatic depending on the symptoms that the animal shows, such as, for example, fluid therapy, antibiotics, analgesics, corticosteroids, feeding through a tube … what the veterinarian considers necessary depending on the severity of the problem.

Liver problems

As you probably already know, the liver is in charge of segregating bile, so any failure or problem in this organ can alter its production, increasing it and causing the substance to accumulate in the stomach, resulting in irritation and inflammation of the gastrointestinal mucosa, until producing the yellow vomit. If this occurs, the cat expels the accumulated bile through vomiting, just as it happens in cases of prolonged fasting.

Given this problem, it is common to observe the white part of the eye and the yellow mucous membranes. Do not hesitate to go to a veterinarian so that, as in the previous case, he applies the symptomatic treatment depending on the symptoms and what is causing the problem of your cat and its severity.


The moment you notice that your cat vomits yellow and it is not for something normal, such as fur balls along with the yellowish liquid, you should go to the vet to rule out possible pathological problems. Your cat may not just vomit a yellowish liquid and it may be accompanied by green, brown, or clear liquid. Even so, you should not let it go and you should follow what the specialist says and these tips on what to do if a cat vomits yellow.

  • Make sure it drinks water, as vomiting causes your cat to become dehydrated. However, offer it in small amounts and often, to prevent him from drinking too much at once because he may vomit more.
  • Offer easy-to-digest food, such as boiled white rice with chicken or wet gastrointestinal food (from the veterinary range), since it is very possible that the stomach lining is irritated.
  • Write down the symptoms you see in your cat so you can tell the vet and make the diagnosis easier.
  • Take a photo of the vomit or take a sample of it to show it to your vet.
  • Offer food or anti-hairball snacks if this is the problem.

Now that you have an answer to your question about why my cat vomits bile or yellow, be sure to give your friend a balanced diet and avoid going long periods of time without eating, as well as keeping deworming guidelines daily to avoid this problem occurs.
