Ask A Vet: Why Does Cat Poop Smell So Bad?

Have you ever wondered why cat poop smells so uniquely horrible? It’s a distinct smell that anyone who has walked by a litter box containing a fresh stool deposit can recognize. While all excrement smells foul, cat poop takes it to a whole other level. But have you ever given the stench any thought?

Poop, in general, smells bad regardless of the species it comes from. It makes sense since waste is like trash for the body – it's the stuff it cannot use and needs to get rid of. Similar to the organic material in our kitchen trash cans, which also stinks for similar reasons.

When we sift through the food in our kitchen, we take all the usable components out and whatever is leftover becomes trash. This is exactly what happens to your cat's diet. His digestive tract takes in the food, just like we unload our grocery bags while organizing meal preparation in our kitchen. The cat's body sorts through the components of the meal, discarding what is not required for their metabolism and energy production.

Now, onto the subject at hand – why does cat poop stink? There are a few reasons for this pungent odor. Firstly, the poop itself releases ammonia, sulfur, nitrogen, and other aromatic gases. All feces contains volatile compounds that are released into the air as soon as it is defecated. These compounds depend on the components of the cat's diet, and since cats are carnivores, they ingest larger amounts of protein than many other animals. Nitrogen, which is a basic component of protein, can contribute to the foul smell.

Another factor is the bacteria present in the intestines. As bacteria digest the portions of waste they can use, gases are produced. Even after the waste is eliminated from the body, these bacteria continue to act and produce gases. The longer the waste sits in the litter box, the more opportunity the bacteria have to produce even more stench. Therefore, it is important to clean out the litter box regularly to prevent the bacteria from making the poop even smellier.

One reason cat poop smells so distinctive is how cats eat and digest food. They are carnivores, which means they have specific dietary needs. This, combined with their digestion process, adds to the unique smell. Furthermore, since cats live and poop inside our homes, their foul waste is in close proximity to our noses. The stench becomes even more pronounced due to the bacteria that start to digest the poop once it is in the litter box.

In conclusion, cat poop smells terrible for a few reasons. It releases compounds such as ammonia, sulfur, and nitrogen that contribute to the odor. Additionally, bacteria present in the intestines continue to produce gases even after the waste is excreted. Due to their specific diet and digestive process, cat poop has a distinct smell that we cannot ignore. To combat the odor, it is essential to regularly clean out the litter box and dispose of the poop while it is still fresh.
