Feline flatulence stems from several different causes, but one of the most common is diet. Foods that cats consume could be upsetting your pet’s stomach and causing gas. While cats can be very picky about what they eat, it could be more than just selectiveness influencing their eating habits. Read on to find out what foods could be irritating your cat’s stomach and causing gas.

One of the most common misconceptions is that cats can drink milk. Surprisingly, cats are actually lactose intolerant. They especially cannot digest lactose as they become older, and giving your cat milk can actually cause health problems. There is no nutritional gain from this beverage, but if your cat really enjoys it, try a lactose-free brand.

Dairy Products

While milk is the number one contender when it comes to digestive issues in your cat, other dairy products could also be the culprit. Be sure to avoid cheese, butter or yogurt when feeding your cat. Similar to milk, cats cannot process rich dairy products, which could lead to digestive problems.

While tuna can occasionally make an enjoyable snack for your cat, it should not be a staple of its diet. Tuna in large quantities can lead to severe health problems for your favorite feline, including mercury poisoning. The canned fish can cause smelly urine as well as a smelly cat, so only give it as a sporadic treat. (Source)

Garlic should be avoided at all costs when it comes to feline diets. It can cause a host of health issues and is easily upsetting to a cat’s digestive system. Cooked garlic or even a hint of garlic powder can set your cat off, so it is best to keep it away from your pet. (Source)

Fructooligosaccharides (FOS) are a natural sweetener found in asparagus, onions, tomatoes and wheat, as well as other fruits and vegetables. FOS is too high in fermentability for cats, whose bodies have difficulty processing it. It can cause gas and a loss of nutrients in felines. (Source)

Grain Products

Since cats are carnivores and should mainly be eating meats and protein-based foods, grains could be the cause of your cat’s stomach problems. Any diet heavy with wheat, corn or soybeans is hard for your cat’s body to digest and is most likely irritating its digestive system. (Source)

Fat Trimmings


Even though cats are carnivores, they should not be eating fat trimmings from meats. Both cooked and uncooked fat can cause an upset stomach, leading to further problems in your cat’s intestines. Save yourself a trip to the veterinarian and give your cat some of your cooked meat instead. (Source)

Dough containing live yeast can be dangerous for cats to consume. The yeast can expand and produce gas in the digestive system. The cat’s stomach can become distended, which is a serious health concern. (Source)

It’s a good rule of thumb to think that if it’s something you wouldn’t eat, your cat probably shouldn’t be eating it either. However, spoiled food is one of the most common causes of gas in cats. Your cat’s body cannot process food that has gone bad, so be kind and only offer your feline fresh food. (Source)
