Cats have digestive tracts that are quite similar to a human or a dog so they are not exempt from passing gas. But if a cat is farting more than you think is normal it may be an indication of something else going on inside its body. Regular monitoring of your cat’s normal gastrointestinal functions will help you be a better pet owner and know when your cat may need to some veterinary attention.

Why Do Cats Fart?

When a cat eats food it travels through the digestive tract so that it can be broken down, have nutrients be absorbed, and then what isn't absorbed is eliminated from the body.

Food starts in the mouth, travels down the esophagus and into the stomach, enters the small intestine, goes to the large intestine, and then exits the body in the form of feces. In the gastrointestinal tract, excess gas may be produced from eating certain gas-producing foods, diseases, or parasite infestations. The gas will build up and eventually exits the body in the form of a fart. Swallowed air can also lead to farting or belching. If a cat doesn't get rid of the gas, pressure in the intestines causes discomfort.

Treatment of Cat Farts

If your cat is farting more than you feel is normal, it may have a digestive issue. Depending on the underlying reason for the gas, treatments will vary.

  • Eradicate intestinal parasites: If your cat has intestinal parasites then medication to kill the invaders will be prescribed by your veterinarian. Some parasites are easier to eradicate than others. Over the counter dewormers are available but since no medication kills all parasites, it’s difficult to know if you are choosing the right one.
  • Assess your cat’s diet: Some cats have less gas on wet or dry food or do better with different ingredients than others. Diets that contain large amounts of common gas-producing foods, such as legumes, or cruciferous vegetables, may also be contributing reasons for a cat farting too much. Switching foods may help decrease farting in cats.
  • Treat intestinal diseases: Many different intestinal disorders can cause gas. Dysbiosis, or an imbalance of the bacteria in the gut, is a common cause that is often corrected with probiotics. More serious diseases include cancers and inflammatory issues. Diarrhea, vomiting, and/or weight loss is usually evident alongside the flatulence in these cases, at least as the disease progresses. Medications may be prescribed to combat the disease and its symptoms, surgery may be recommended, and special diets may be discussed to improve the health of the intestinal tract.

Diagnosing the Problem

One of the first things you should do if you think your cat has too much gas is to make an appointment with your veterinarian. Bring a fecal sample in with you to be checked for parasites. The fecal exam will look for parasites such as coccidia, roundworms, and hookworms that could be causing excessive gas. This is a simple and routine test that can also be done on a yearly basis, especially if your cat goes outdoors.

If parasites are not the reason for excessive farting, your cat may have an intestinal disease, particularly if additional symptoms are present. A full physical examination will include your veterinarian feeling the intestines to see if anything appears to be abnormal. X-rays, ultrasounds, blood tests, biopsies, and other diagnostics may be necessary. Exploratory surgery is sometimes the only way to retrieve appropriate samples and visualize the intestinal tract once other methods of diagnosis have been exhausted.

If your cat has a clean bill of health, then you should look at its diet. Ask yourself: Has there been a recent dietary change or indiscretion? Did you change your cat's food or treats? Did your cat get into something it shouldn't have eaten? Any of these things may be causing excessive gas. If your cat gets different types of foods on a regular basis, consider keeping a food journal to track the relationship between diet and your cat's gas.

How to Prevent Cat Farts

The best way to keep your cat's farts to a minimum is to feed a quality cat food that agrees with your cat and to minimize dietary changes. Regular administration of probiotics may also help. Avoid feeding items containing lactose, such as milk, and take your cat in for regular check-ups with your veterinarian to catch any intestinal problems early. Regular administration of intestinal parasite preventatives is also recommended in many cases.

If you suspect your pet is sick, call your vet immediately. For health-related questions, always consult your veterinarian, as they have examined your pet, know the pet’s health history, and can make the best recommendations for your pet.
