Do Cats Fart? Why Your Cat Might Be Gassy

If you’ve ever been lounging with your cat and suddenly caught a whiff of something… unexpected, you’re not alone. Yes, cats can fart, and while it’s not the most glamorous topic, it’s one every cat parent eventually wonders about. Understanding why it happens (and when it’s a problem) can help you keep your feline friend feeling their best.

Can Cats Fart?

Absolutely. Like humans and other animals, cats naturally produce gas as part of the digestive process. Most of the time, it’s perfectly normal and goes unnoticed — feline farts are typically silent and infrequent. But when your cat’s gas becomes frequent or particularly smelly, it can signal that something’s not quite right in their digestive system.

Why Does My Cat Fart So Much?

Excessive gas in cats often comes down to diet, digestion, or gut microbiome imbalance. Some common causes include:

• Swallowed air: Cats that eat too quickly or gulp their food take in air, which can lead to bloating and gas.

• Diet changes: Switching foods too quickly can upset the gut microbiome¹. Gradual transitions are key, typically recommending a 10-day-long period.

• Food intolerances or allergies: Just like people, cats can have trouble digesting certain proteins or carbohydrates¹. Foods high in soy, dairy, or certain grains may not agree with sensitive stomachs.

• Gut health issues: Imbalances in bacteria within the gut can lead to inefficient digestion and excess gas¹.

Studies have found that the composition of gut bacteria in cats directly impacts digestive health and stool quality². That means keeping your cat’s microbiome healthy isn’t just about avoiding farts — it’s essential for their overall wellbeing.

Why Do Cat Farts Smell So Bad?

Let’s be honest — some cat farts could clear the room. The unpleasant odor usually comes from sulfur-containing gases released when gut bacteria break down certain foods. Protein-rich diets can contribute to stronger smells, but persistent odor may point to an imbalance of the gut microbiome . When gut bacteria are thriving, these gases are minimized — another reason to keep digestive health top of mind.

How to Relieve Gas in Cats

While the goal is not to completely eliminate farts (that’s not healthy, either), if your cat seems uncomfortable or unusually gassy, here are a few gentle ways to help:

• Check their diet. Look for premium-quality cat food made with easily digestible ingredients that support gut health. Avoid sudden changes or overly rich foods like treats or human foods.

• Slow down mealtime. Try a slow-feeder bowl to reduce swallowed air.

• Encourage activity. Regular play helps stimulate digestion and prevent bloating.

• Support their gut microbiome. Incorporating foods or supplements with prebiotics and probiotics can help balance good bacteria and reduce gas.

• Monitor for patterns. Keep track of when the gas occurs — after certain meals, treats, or behaviors — and share these details with your vet if needed.

If gas is persistent or your cat seems distressed, it’s worth consulting a veterinarian. Chronic digestive issues can signal food sensitivities or other underlying health concerns that need attention.

The Bottom Line

So, do cats fart? They sure do — and while the occasional toot is nothing to worry about, since farts are considered a normal part of healthy digestion, frequent or foul-smelling gas can be your cat’s way of saying their tummy needs a little extra care. By focusing on digestive health, balanced nutrition, and a happy gut, you’ll be setting your cat up for a life of comfort (and fresher air for everyone).
