Cat Vomiting During FIP Treatment, What Should You Do?

One of the common symptoms experienced by cats infected with FIP (Feline Infectious Peritonitis) is vomiting. Even the healthiest cats can experience vomiting under certain conditions. In many cases, this is not a cause for concern, unless it occurs continuously and is accompanied by other symptoms. Another worrisome situation is when a cat vomits frequently and regurgitates anything recently ingested, as this can affect the cat's health, particularly in FIP cases.

What Causes Cat Vomiting?

It's important to remember that vomiting in cats is often an early sign of an illness. It can be caused by many factors, one of which is the FIP virus in cats.

Similar to humans, cats can vomit for various reasons. Some causes of cat vomiting are relatively harmless and may even resolve on their own. Other causes can be much more serious.

Here are some common reasons why cats vomit:

Feline Infectious Peritonitis (FIP) Virus Infection: Vomiting is one of the symptoms that occur in cats infected with the FIP virus. If a cat experiences vomiting along with other FIP symptoms such as fever, loss of appetite, reduced drinking, and other symptoms, prompt veterinary examination is essential for effective treatment.

Cancer: Digestive tract cancer is quite common in cats and can cause vomiting by disrupting normal digestion. Cancer in other areas of the body can also cause nausea, discomfort, and malaise, which can lead to vomiting.

Specific Diseases: Chronic diseases like kidney disease, pancreatitis, and hyperthyroidism can cause chronic nausea and vomiting due to various mechanisms. Addressing the underlying causes of vomiting requires identifying the underlying condition, and many of these conditions require lifelong management.

Gastroenteritis: Gastroenteritis is basically a term for a stomachache, which can occur due to improper eating habits, toxins, or medication side effects, among other causes. Some causes of gastroenteritis are mild and will resolve on their own. Other causes can be more serious and require veterinary attention.

Foreign Objects or Obstructions: If your cat ingests a foreign object—such as toys, string fragments, hair ties, or other items—it can cause blockages and damage to the digestive tract, leading to vomiting. This cause of vomiting is serious and requires immediate veterinary attention.

Food Allergies and Inflammatory Bowel Disease: Although allergies are relatively rare in cats, they can cause vomiting. When cats consume triggering foods, inflammation in their digestive tract can lead to regurgitation. Some cats may also experience chronic diarrhea due to this condition.

Cat Vomiting: When to Worry!

If your cat vomits several times a day, you notice an increase in vomiting frequency, or if your cat vomits blood, it's advisable to discuss this issue with your veterinarian.

Vomiting in cats is very concerning when accompanied by other symptoms such as:

  • Loss of appetite

  • Lethargy

  • Fever

  • Diarrhea

  • Other changes in health and behavior

If you observe these symptoms in your pet, contact your veterinarian for appropriate action.

Treating Cat Vomiting

Many cat owners wonder what to give a vomiting cat. However, because vomiting can be caused by various conditions, there are many different treatments.

If your cat is vomiting due to the FIP virus, cancer, or systemic diseases like chronic kidney disease, diagnosing and treating the underlying condition will be the primary goal.

In cases of mild vomiting due to gastroenteritis, the veterinarian will prescribe supportive care. Sometimes, your cat may need a change in diet or even a prescription diet, especially if the vomiting is caused by a food allergy or inflammatory bowel disease.

Treating FIP-Related Vomiting

During FIP treatment, a cat may vomit due to stress factors. When a cat experiences vomiting, it's important to know the appropriate treatment method. Oral treatment is not recommended in this condition, as it can affect the absorption rate of GS-441524. Here is why oral is not recommended:

Therefore, we always recommend treatment through injection if the cat is still experiencing vomiting symptoms. Both methods, injection and oral, have the same effectiveness; the difference lies in the absorption rate of the drug in the cat's body.

Treatment via injection allows the drug to be injected directly into the cat's body, reaching the target more quickly and effectively. In cases of vomiting in FIP cats, injection treatment can provide a more direct effect and reduce the time the drug needs to work.

However, it's crucial to always consult with a veterinarian before deciding on the appropriate treatment method for your cat. The veterinarian will thoroughly evaluate the cat's condition and provide the best guidance regarding suitable treatment.

If your pet cat is showing FIP symptoms, take them to the nearest veterinarian for proper diagnosis and treatment. If you would like further consultation regarding FIP and its treatment, you can contact (through email: on WhatsApp or visit the CUREFIP Facebook Page for us to assist you.
