Do cats fart? The answer is yes. Like humans and many other mammals, cats can produce intestinal gas, which is then naturally expelled. However, their flatulence often goes unnoticed because it is generally discreet and infrequent.
Therefore, a cat that occasionally farts does not necessarily have a health problem. The digestion of food can naturally lead to the formation of a small amount of gas in its digestive system.
However, if flatulence becomes frequent, particularly foul-smelling, or appears with diarrhea, vomiting, loss of appetite, or a swollen belly, it becomes important to investigate the cause.
In this article, discover why cats fart, what are the main causes of gas, how to tell if this flatulence is normal, and in what situations it is best to seek advice from a veterinarian.

Do cats fart, and is it normal?
Yes, cats can fart. During digestion, gas can form in the intestine. Some of it can be absorbed by the body, while the rest is naturally expelled.
In a healthy cat, these flatulences are generally occasional and discreet. It is even possible to live with a cat for several years without really noticing that it passes gas.
Contrary to some misconceptions, the fact that a cat farts from time to time is not necessarily a sign of a digestive disorder. It is mainly the frequency, the smell, and the possible presence of other symptoms that should draw your attention.
A cat's well-being also includes its daily comfort. For occasions when you want to give it an elegant touch, the velvet cat bow tie combines a soft material with an anti-strangulation clasp designed to open under strong tension. The bow is removable, allowing the collar to be easily adapted to your companion's habits.

How often can a cat fart?
There is no precise number of flatulence considered normal for all cats. Diet, the speed at which the animal eats, its age, and its digestive system can all influence gas production.
The important thing is to observe a change from its usual habits. A cat that occasionally passes gas without any other symptoms is generally less concerning than an animal that suddenly starts having flatulence several times a day.
| Situation | Possible interpretation | To watch out for |
|---|---|---|
| Occasional fart | Normal digestion | No associated symptoms |
| Frequent gas | Diet or digestion to examine | Evolution over time |
| Very foul-smelling gas | Possible digestive disorder | Stool and appetite |
| Gas + diarrhea | Possible digestive problem | Consult if it persists |
Why do we rarely hear a cat fart?
Cat flatulence is generally silent. The expulsion of gas does not necessarily produce the sound associated with human flatulence.
Thus, it sometimes happens that an owner only notices an unusual smell without immediately understanding its origin. If this remains exceptional and the cat behaves normally, there is generally no reason to worry.
Why is my cat farting?
The causes of gas in cats can be numerous. Diet is one of the first avenues to explore, especially when a recent change in food precedes the onset of flatulence.
A too rapid dietary transition can temporarily disrupt the digestive system. When new food needs to be introduced, a gradual transition generally allows the body to adapt more easily.
A cat that eats very quickly can also swallow more air during its meal. This air can then move through the digestive system and contribute to gas formation.
| Possible cause | Why it can cause gas? | Solution to consider |
|---|---|---|
| Change of diet | Digestive adaptation | Gradual transition |
| Meal eaten quickly | Air ingestion | Slow down food intake |
| Poorly tolerated food | Difficult digestion | Seek veterinary advice |
| Intestinal parasites | Digestive disruption | Veterinary diagnosis and treatment |
| Digestive disorder | Disrupted intestinal function | Monitor other symptoms |
Can food make a cat fart?
Yes. Some foods may be less well tolerated by an animal and cause more digestive fermentation. A sudden change in kibble or wet food can also temporarily alter its stool and increase gas production.
It is best to avoid regularly giving cats table scraps or foods that are not adapted to their nutritional needs. Their digestive system is not identical to ours, and some foods intended for humans can be poorly tolerated, or even dangerous.
Can kittens have gas?
Yes, a kitten can also have flatulence. Its digestive system is still developing, and changes in diet, intestinal parasites, or certain digestive disorders can promote the appearance of gas.
Age also allows for a better understanding of your pet's nutritional needs and development. If you have welcomed a feline whose precise birth date you do not know, discover how to determine a cat's age using the most reliable methods.
In a very young kitten, significant flatulence accompanied by a very swollen belly, diarrhea, vomiting, loss of appetite, or lack of energy should be taken seriously.

Why do my cat's farts smell bad?
Flatulence can naturally have an unpleasant odor. However, if your cat regularly starts producing particularly foul-smelling gas, it may be useful to pay more attention to its diet and digestion.
Poor food tolerance, a change in diet, certain parasites, or various gastrointestinal disorders can alter the odor of gas and stool.
However, odor alone cannot establish the cause. You must observe the animal's overall behavior: appetite, stool, energy, weight, and frequency of flatulence.
What symptoms should be observed along with gas?
- Persistent diarrhea or unusual stool.
- Repeated vomiting.
- Loss or decrease of appetite.
- Abnormally swollen or painful belly.
- Unexplained weight loss.
- Lack of energy or change in behavior.
When flatulence becomes unusual and is accompanied by one or more of these symptoms, it is best to seek the advice of a veterinarian rather than changing its diet several times without knowing the origin of the problem.
How to reduce gas in a cat?
If your cat regularly experiences flatulence without showing any alarming signs, some adjustments to its habits can sometimes help improve its digestive comfort. The goal is not necessarily to completely eliminate gas, as a small amount can be normal, but to identify the cause when it becomes frequent.
Start by observing its diet. A recent change in kibble or wet food can explain a temporary modification of its digestion. When changing its food, opt for a gradual dietary transition rather than an abrupt replacement.
Also, avoid multiplying table scraps and foods intended for humans. A complete diet adapted to your companion's age, weight, and needs generally remains the best foundation.
What to do if my cat eats too fast?
A cat that rapidly devours its meal can swallow more air. If your companion eats very quickly, you can try to divide its daily ration into several small meals.
An adapted bowl or a device to slow down food intake can also be useful. The goal is simply to encourage the cat to eat more gradually, without turning mealtime into a source of frustration.
| Habit | Possible action | Objective |
|---|---|---|
| Change of food | Make a gradual transition | Facilitate digestive adaptation |
| Cat that eats too fast | Fractionate meals | Slow down food intake |
| Table scraps | Limit them | Avoid poorly tolerated foods |
| New flatulence | Observe recent changes | Identify a possible cause |
| Persistent gas | Seek veterinary advice | Look for a digestive cause |
Should I change the kibble of a cat that farts a lot?
Not systematically. Immediately changing food at each episode of flatulence can, on the contrary, further disrupt the digestive system, especially if the changes are frequent and abrupt.
If you suspect a poor food tolerance, first observe the frequency of gas, the appearance of the stool, and any other symptoms. A veterinarian can help you determine if a diet modification is actually relevant.
Also, avoid removing several ingredients at random. When an intolerance or food reaction is suspected, a structured approach is preferable so as not to unbalance your pet's diet.

When should flatulence be a concern?
Occasional flatulence in a cat that eats normally, plays, and has usual stools is rarely concerning. The situation warrants more attention when flatulence suddenly becomes frequent or is accompanied by other changes.
Gas associated with repeated vomiting, persistent diarrhea, weight loss, loss of appetite, or lethargy can indicate a digestive problem requiring veterinary attention.
An abnormally swollen or painful belly should also draw your attention. If your cat appears to be in pain, becomes very weak, has breathing difficulties, or if its condition rapidly deteriorates, contact a veterinarian promptly.
| Situation | Level of vigilance | Reaction |
|---|---|---|
| Occasional fart | Low | Simple monitoring |
| Gas more frequent than usual | To monitor | Observe diet and stool |
| Gas + persistent diarrhea | Important | Seek veterinary advice |
| Gas + repeated vomiting | Important | Consult a veterinarian |
| Swollen and painful belly | High | Contact a veterinarian promptly |
| Significant lethargy | High | Consult promptly |
My cat is farting and has diarrhea: what should I do?
When gas is accompanied by diarrhea, several causes are possible: dietary change, poorly tolerated food, parasites, or another digestive disorder.
Monitor its general condition and ensure it continues to drink. If diarrhea persists, recurs, contains blood, or is accompanied by vomiting, lethargy, or loss of appetite, seek advice from a veterinarian.
Particular vigilance is necessary in kittens, elderly or fragile cats, as they may be more susceptible to the consequences of a digestive disorder.
My cat farts but seems healthy: should I worry?
If your cat occasionally passes gas but maintains a normal appetite, usual stools, stable weight, and its daily behavior, there is generally no cause for concern.
Simply continue to observe the evolution. If the frequency or odor of flatulence changes suddenly, investigate what has recently changed in its daily life, especially its diet.
Do cats fart: what to remember
So, do cats fart? Yes, and it is a natural phenomenon. As with other mammals, digestion can produce gas that is then expelled through the intestine.
In a healthy cat, flatulence is generally rare and discreet. An occasional fart is not necessarily a sign of a problem.
However, a sudden increase in gas, a particularly strong odor, or the simultaneous appearance of diarrhea, vomiting, loss of appetite, or a painful belly warrant more attentive monitoring.
Diet, the speed at which the cat eats, and certain digestive disorders can promote flatulence. Instead of constantly changing its diet, observe its habits and seek veterinary advice when symptoms persist.
