Why Does My Cat Smell Like Sulfur? (Or Rotten Eggs)

OK, why does my cat smell like sulfur? Your cat likely smells like sulfur due to hydrogen sulfide. This gas is responsible for the stink of rotten egg farts. Sulfur is an important component in the diet of cats. However, too much can result in stinky flatulence. In addition, certain disorders and gastrointestinal difficulties may also contribute to the sulfurous odor of your cat’s flatulence.

The causes of sulfur-smelling cat farts are relatively simple to comprehend, as they directly relate to what generates gas in cats. By understanding the causes of flatulence, the riddle of rotten egg farts can be answered.

Your cat’s digestive (GI) tract is home to many bacteria, viruses, fungi, and other microorganisms. This collection is known as the intestinal microbiota. Yes, we humans also have this tiny colony living within us! The gut microbiota population plays a crucial role in the digestion and fermentation of our food. Bacteria in the large intestine are responsible for the production of various gases. The following gases are generated by the fermentation of fiber and complex carbohydrates:

  • Hydrogen
  • Methane
  • Nitrogen
  • Carbon dioxide
  • Oxygen

It sounds like a full-fledged scientific experiment is taking place in your cat’s stomach! A normal level of gas production is present. The problem arises when the gas output becomes excessive or sulfur-smelling.

Is too much flatulence bad for my cat?

Your cat’s excessive farts may be an indication that anything is wrong. Typically, this occurs when you change your cat’s diet. It can also occur if your cat has gotten into the garbage and eaten something he shouldn’t have. Additionally, your cat may be suffering from a dietary intolerance.

The digestive enzymes of your cat are incapable of breaking down specific fibers and complex carbs. The bacteria’s ability to consume and ferment nutrients is diminished when this occurs. This causes bigger volumes of gas to accumulate, resulting in sulfur-smelling cat farts.

Excessive flatulence is caused by a nutritional issue that can be easily remedied. However, you should consult your veterinarian if you cannot determine the cause. Your cat may suffer from a food allergy, inflammatory bowel illness, infection, or underlying GI disorder.

Why Does My Cat Smell Like Rotten Eggs?

The five gases listed above typically cause rather odorless flatulence. They account for 99 percent of your cat’s farts and, unless excessive, are generally normal.

Those that smell like rotten eggs catch our attention and make us wonder if something is wrong with our pets. Even your cat may be perplexed by the odor, and I’ve witnessed cats lifting their tails to take a whiff for themselves.

Hydrogen sulfide is the gas responsible for this rotten egg or sulfurous-smelling farts. This gas is a byproduct of your cat’s colon’s digestive process.

When Should I Worry About My Cat’s Stinky Flatulence?

A diet rich in red meats, eggs, and other types of protein, such as beans, will result in sulfurous, offensive flatulence. If any of these sulfur-rich substances are present in your cat’s food, you may need to switch his food.

However, if the sulfur fart odor persists and you constantly pinch your nose, you must investigate the situation further. The presence of foul-smelling, sour feces, or diarrhea, together with foul-smelling, rotten-egg-smelling flatulence, is another reason you must take your feline to a vet immediately. Your cat may be experiencing any of the following illnesses:

  • Intestinal parasites
  • Feline colitis
  • Functional bowel disorder
  • Bowel inflammatory disease
  • Pancreatitis

It would help if you took your cat to the veterinarian so he may do a thorough inspection. If these problems are ruled out, your veterinarian may suggest testing for food allergies or intolerance.

Is My Cat In Pain If It Farts Excessively Or Smells?

Have you ever witnessed a human infant with colic? They scream bloody murder and frequently contort their bodies in anguish from cramps and gas. If your cat has excessive gas and foul-smelling flatulence, his gastrointestinal tract is under stress. Typically, he will also have stomach pains and general discomfort.

Typically, cats do not exhibit pain; therefore, you may not notice if he is struggling with cramps. Take him to the veterinarian if you detect a rapid change in his behavior, including lack of appetite, diarrhea, lethargy, and stinky flatulence.

How Can I Stop My Cat’s Stinky Flatulence?

If your veterinarian has checked out any underlying health concerns, you can conclude that your cat’s diet is the reason for his foul-smelling, rotten-egg-smelling flatulence. Here are several strategies to assist your cat in reducing his sulfur emissions (and clear the air around the home).

Try A Different Diet

Perhaps the kibble you are feeding your cat contains excessive protein and other sulfur-producing substances. You could attempt to alter his diet. Ensure a smooth transition by introducing the new food in small amounts and removing the old food gradually.

If you abruptly alter your cat’s diet, his digestive tract may resist and cause excessive flatulence. Let him gradually adjust to the new meal over several days.

Do not permit your cat to scavenge

Cats are constantly on the lookout for anything that tastes and smells nasty. This means they will rummage through the garbage, hop on tables, the compost heap in the garden, and even pick up dead birds in the park.

Stop your cat from scavenging and consuming unwanted objects. This will keep his digestive tract in a much healthier condition and lessen his odorous flatulence.

Avoid Offering Your Cat Snacks

It is always tempting to share your food with your cat, particularly when he looks at you with such pleading eyes. However, your cat’s digestive tract is fragile, so feeding him table scraps is asking for trouble. Avoid feeding your cat table scraps and ensure he only consumes his food. This will eliminate the possibility of another sulfuric explosion.

Conclusion

Any cat owner has previously encountered these rotten egg-smelling farts. Occasionally, it is humorous and probably nothing to worry about. However, if you have a continual stream of sulfur-smelling farts, you should seek expert aid if the tips above do not work.
