Why does my cats poop smell like death? It might be because of many reasons but I will discuss all those reasons with you in this post.

Why Does My Cats Poop Smell Like Death

My first question is what do you think is the reason that your cat’s poop smells like death? Is it due to the diet or due to the environment or due to the stress? Let us discuss each of these reasons.

Why Does My Cats Poop Smell Like Death?

Here are a few reasons why your cat’s poop could smell so bad.

Diet Change

If you change your cat’s diet, this could be the reason why his poop smells so bad. The cat’s digestive system is not able to process the new food properly.

It will take some time for the digestive tract to adjust to the new diet.

As a result, your cat may start to produce more gas and other gas-related problems. You should not feed your cat any new foods before giving it a couple of weeks or months to adjust to the new diet.

Too Much Protein

It is a well-known fact that cats are carnivores. They need protein to keep their body healthy.

If you feed your cat too much protein, this could be the reason why your cat’s poop smells so bad.

The smell is a result of bacteria and other microorganisms feeding on proteins that are not used by the cat.


Parasites can cause inflammation in your cat’s intestines.

This inflammation can change your cat’s digestive system and result in foul-smelling feces. 

They May Be Constipated

If your cat is constipated, this could be the reason why his poop smells so bad.

A cat’s digestive system is made up of two sections: the small intestine and the large intestine.

The small intestine is responsible for digesting the food that the cat eats.

The large intestine is responsible for absorbing the nutrients from the food that is digested by the small intestine.

If the cat’s large intestine is not working properly, this can result in constipation.

When the feces pass through the small intestine, it is able to absorb the nutrients.

However, if the feces is unable to pass through the large intestine, the feces will smell bad.

The cat’s poop may also be hard and black in color.

What Can I Do To Stop The Smell?

There are numerous things you can do to help stop the bad smell of your cat’s poop drifting around your home.
