Do Cats Fart? What It Means for Your Cat’s Health
Cats are mysterious creatures, aren’t they? You watch them lounge in the sun, pounce on a toy, and then silently slip away. So when you wonder “do cats fart”, you’re touching on one of those slightly embarrassing but entirely normal topics of feline life. In fact, while it might surprise you, occasional flatulence in cats is perfectly natural — though frequent or foul-smelling gas may signal a bigger issue.
Here’s a startling stat to start: according to one expert, healthy cats may only pass gas one to two times per day, compared to the 14 to 23 times per day humans do.
In this in-depth article I’ll cover everything you need to know about feline flatulence, gastrointestinal health, diet and digestion, and when to call the vet. Drawing on veterinary research, nutritional science, and practical experience, I’ll help you understand the “why”, “how”, and “what to do” when it comes to your cat’s digestive system.

What exactly does “do cats fart” mean?
Understanding feline flatulence and digestive gas
When we ask “do cats fart”, we’re really asking about whether cats pass intestinal gas the way humans and dogs do. The short answer is yes — cats have a gastrointestinal (GI) tract, they digest food, microbes break down that food, gas is produced and may be released.
However, the frequency, volume, sound, and odour differ. Because cats are obligate carnivores (they evolved eating mostly meat) and have smaller digestive tracts relative to body size, they typically generate less gas, often silently.
Here are key points:
- “Flatulence” = release of gas via the rectum (farting).
- Occasional gas in cats is normal.
- Excessive or smelly gas may indicate digestive upset, dietary issues, parasites, or disease.
Why do cats fart? — The causes of feline gas
Breaking down diet, digestion, swallowed air, and health conditions
Understanding why your cat might fart is key to managing it. Here are the main causes of feline flatulence and digestive gas:
| Cause | How it leads to gas | What you’ll often observe |
| Swallowed Air | Eating too fast, gulping food or water, or vocalising while eating can cause extra air in the GI tract which eventually gets released. | Rapid eating, noisy meals, occasional gas. |
| Dietary Ingredients | Cats evolved with low-carb, high‐protein diets. Modern foods high in fibre, legumes, soy, or carbohydrates may ferment in their gut and create more gas. | Dietary changes, smelly stools, more gas. |
| Food Sensitivity / Allergy | If a cat is sensitive to a protein, carbohydrate, or ingredient, digestion may be inefficient, resulting in gas, bloating or GI upset. | Itchy skin, vomiting, gas, bowel changes. |
| Parasites / Infections / GI Disease | Intestinal parasites (worms, protozoa), bacterial overgrowth, inflammatory bowel disease (IBD) or malabsorption conditions can all cause excess gas. | Diarrhoea, vomiting, weight loss, frequent gas. |
| Rapid Food Change or Low Digestibility | Switching foods too quickly or feeding a low-quality diet can upset the GI flora producing extra gas. | Recent change in diet, new food, increased gas. |
Because so many different factors can cause gas in cats, paying attention to your cat’s overall health and behaviour is critical.
How often do cats fart? And when should you worry?
Interpreting frequency, sound, smell and signs
Let’s answer two questions: (a) what’s “normal” and (b) when should you be concerned?
Normal frequency:
- Many vets estimate a healthy adult cat may pass gas once or twice a day, although many cat owners won’t even notice.
- Because cats often fart quietly and with little odour, you may never go counting. The absence of smell or sound often means you’re just unaware.
When you should worry:
- If your cat’s farting more often than usual OR the smell or sound has suddenly worsened.
- If gas is accompanied by other symptoms: vomiting, diarrhoea, weight loss, poor appetite, lethargy.
- If your cat has a known GI condition or has just had a major diet or environment change.
Here is a quick checklist:
- ✅ One or two gas releases per day (likely fine)
- 🚨 More than a few times a day, or very smelly or loud (consider vet)
- 🚨 Plus vomiting, diarrhoea, weight change, or behaviour change (definitely vet)

How diet and gut health impact “do cats fart”
Nutrition, fibre, carnivore physiology and gut microbiome
Since your cat’s diet is one of the most controllable factors in their digestive health, it’s worth diving into it.
Carnivore physiology
Cats evolved to eat prey: high‐protein, moderate fat, very low carbohydrate. Their digestive systems reflect that. Excess carbohydrates or poorly digestible fibre may lead to more gas production.
Fibre, legumes and gas
Foods that include legumes (peas, lentils), soy, or high fibre may ferment in the lower gut (colon) producing gas.
As one article points out: “Cats are obligate carnivores… certain diets can have … more vegetables or carbs… causing more gas.”
Gut microbiome and digestion
The microbial community in your cat’s gut affects how well food is broken down. Imbalance (dysbiosis) may lead to gas, bloating, poor nutrient absorption, and even health conditions.
Practical diet tips to reduce gas
- Introduce new foods slowly over 7-10 days, mixing with the old diet to avoid sudden GI upset.
- Choose highly digestible, animal‐based protein foods.
- Avoid excessive legume or high‐vegetable formulas if you suspect gas issues.
- Avoid feeding too fast (see “swallowed air” above).
- Consider adding probiotics (under vet guidance) if your cat has recurrent GI issues.
Diagnosing and treating excessive feline flatulence
When to call the vet, what tests are done, and what treatments exist
If you’ve noticed a change in how often your cat farts, or your cat shows GI symptoms, here’s what a vet will typically consider and how things are treated.
Diagnostic path
- History: diet changes, how often, smell, stool consistency, other signs (vomit, weight loss).
- Physical exam: vet palpates abdomen, looks for bloating or discomfort.
- Fecal exam: check for parasites (worms, protozoa) that can cause gas.
- Sometimes blood work, ultrasound or x‐rays if GI disease is suspected.
Treatment/Management
- If diet or food sensitivity: change food gradually, use hypoallergenic diet if needed.
- If parasites/infection: appropriate medication (dewormers, antibiotics).
- If GI disease (like IBD): long-term management with diet, medication, probiotics.
- Feeding changes: smaller meals, slower eating bowls, reduce stress during feeding.
- Monitor and follow-up: many conditions improve within a week or two if diet is the cause.
Note of reassurance
Most of the time, a cat farting here and there is not a cause for alarm. It’s when patterns change (frequency, smell, plus other signs) that you need to act. As one review says: “Occasional flatulence is a natural part of a healthy digestive system.”

Myths and FAQs about “do cats fart”
Clearing up common misunderstandings around feline digestion
Let’s dispel a few myths and answer some frequent questions:
Myth 1: Cats never pass gas because they’re elegant creatures.
False. They can pass gas — it’s just usually quieter and less frequent.
Myth 2: If a cat farts, it must be majorly unwell.
No. Occasional gas is fine. But a sudden increase or smell might signal concern.
Myth 3: Only old or sick cats fart.
Not exactly. Young, old, or adult cats all may pass gas. What matters is frequency, change, and associated symptoms.
Practical tips to reduce and manage your cat’s gas
Everyday habits to keep your cat’s digestive system running smoothly
Here are actionable steps to help minimise gas, keep your feline comfortable, and maintain a healthy gut:
- Feed a high-quality, species-appropriate diet: Focus on animal-based proteins, moderate fat, low unnecessary carbs/fibre.
- Transition food slowly: When changing brand or formula, do so over 7-10 days: mix old + new gradually.
- Use slow-feeder bowls or puzzle feeders if your cat eats quickly, to reduce swallowed air.
- Avoid dramatic diet swings and human food treats that may upset digestion.
- Provide regular vet check-ups, including stool checks for parasites especially if your cat goes outdoors.
- Monitor stool, appetite, weight and behaviour: any changes with gas may signal a deeper issue.
- Limit excessive fibre/legumes in diet if gas is a recurring problem (under vet advice).
- Introduce probiotics only on vet recommendation, especially if your cat has known GI issues.
- Keep your home stress-free at feeding times: stress may indirectly affect digestion.
- Document your cat’s diet and gas pattern: note when you changed food, meals per day, type of bowl, and any changes in gas. This helps vet diagnosis if needed.
Conclusion
So, to answer the question: yes — cats do fart. It’s a normal part of feline digestive physiology. But because of their evolutionary diet and digestive system, it tends to happen less often and less noticeably than in humans.
The key takeaway: occasional, quiet, barely noticeable gas is normal. If you notice a change in frequency, smell or behaviour — or your cat has other symptoms like vomiting, diarrhoea or weight loss — then it’s time to consult your veterinarian.
By focusing on diet, feeding habits, gut health and regular vet care, you can help ensure your cat’s digestive system stays comfortable, efficient and relatively gas-free. Because despite their dignity, even your elegant feline may let one slip — and that’s just fine.
Love your cat’s ever-delicate gas? Probably not. But love them enough to keep them healthy? Absolutely.
FAQs
1. Are cat farts really silent?
Yes — most cat flatulence is quieter and less noticeable than in dogs or humans.
2. Why does my cat’s fart smell so bad all of a sudden?
Smelly gas may point to dietary intolerance, infection, parasites, or malabsorption.
3. How often is ‘too much’ farting in a cat?
There’s no hard number, but more often than normal for your cat, especially if accompanied by other GI signs, is a red flag. Some experts say more than 2 per day is likely too many.
4. Can I buy over-the-counter gas relief for my cat?
Only under veterinary guidance. Medications like simethicone exist, but they don’t treat the root cause.
5. Will switching food completely eliminate my cat’s gas?
It might, if diet is the cause — but you must switch gradually over a week, and monitor. If no improvement, vet consult is needed.
