What Causes Smelly Poop in Cats?

You can’t expect your cat’s stools to smell pleasant, if they start to take on a particularly strong or foul odor, it could be an indication of a problem. Many health problems in cats are accompanied by changes in stool including diarrhea and foul-smelling stools. So, the first thing you should do if your cat develops smelly stool is to consult your veterinarian.

Your veterinarian will want to know when your cat’s stool changed and whether he’s been experiencing any other symptoms. It may help to bring a stool sample along for testing – otherwise, you may need to take one after the visit and return to have it tested. With the sample, a history of your cat’s symptoms, and a physical exam, your vet should be able to identify the problem.

Here are some of the most common cause of smelly poop in cats:

  • Bacterial Infection – Bacteria like E. coli and salmonella can cause infections which may lead to inflammation of the digestive tract and digestive symptoms like diarrhea and smelly poop.
  • Intestinal Parasites – Several intestinal parasites like giardia, coccidia, and trichomonas are known for causing intestinal inflammation, gas, diarrhea, and odor.
  • Digestive Disorders – Various digestive disorders that impact your cat’s ability to digest food and absorb nutrients may result in gas, diarrhea, or increased feces odor.
  • Poor Diet – If your cat suddenly develops smelly poop, it could be an indication of a food allergy or sensitivity. It may also be that your cat is simply having a hard time digesting his food, which may be the case if you’re feeding him a low-quality or grain-based cat food.

Once your veterinarian diagnoses your cat’s issue, you can start talking about treatment options. In cases where there is no serious underlying problem, your cat’s smelly stools may resolve themselves within a few days. If the problem persists or if your cat develops bloody stools, vomiting, or low energy, it could be a sign of an emergency situation, and you should talk to your vet right away.

If your veterinarian diagnoses your cat with one of the problems listed above, you’ll need to work together to determine the best course of treatment. Over time, the treatment should help normalize your cat’s stools and resolve the problem. In the meantime, however, there are some things you can do to reduce litter box odor.

6 Tips for Dealing with Litter Box Odor

If you stick your head in the litter box and take a big whiff, you can’t expect it to smell very nice. But there is a difference between odor being contained to the litter box and odor pervading the entire house. Fortunately, there are some simple things you can do to control litter box odor.

Here are 6 simple tips for dealing with litter box odor:

  1. Switch to a covered litter box. If the issue is simply that litter box odor is spreading throughout the house, switching to a covered litter box might help keep it contained. You can find covered litter boxes that include a filter as well to help keep odor down.
  2. Try a new cat litter. Sometimes switching to a different type of cat litter can help reduce litter box odor. Look for a litter that absorbs well and forms hard clumps to seal in odor.
  3. Scoop the litter box more frequently. The more you scoop the litter box, the less there is to produce odor. It is best to scoop clumps every day or every other day and to refresh the entire litter box once every week or so, depending how many cats you have.
  4. Add another litter box. If you have more than one cat, adding an extra litter box may help to keep litter box odors from piling up as quickly.
  5. Use baking soda or a litter box deodorizer. Sometimes sprinkling baking soda or a litter box deodorizer over the litter in the box can help keep litter box odors down.
  6. Move the litter box to a new location. If you’re smelling the litter box on a daily basis, you may want to move it to a different location. Placing it in a well-ventilated area rather than the spare bathroom is a good idea. Plus, your cat will appreciate being able to breathe more easily.

In addition to trying some of the tips listed above, you may want to think about changing your cat’s diet. If your cat’s stool is very smelly, it may be an indication that he isn’t digesting his food properly and a change in diet might help. Keep reading to learn more.

 

What to Look for in a Cat Food for Smelly Poop

All cats have the same basic requirements when it comes to a balanced diet, but some cats digest food differently. Your cat is an obligate carnivore which means that he has a biological need for protein in his diet – his body was simply designed to digest and obtain nutrition from animal sources more effectively than from plant sources. If you’re feeding your cat a low-quality cat food or a product that doesn’t list an animal protein as the first ingredient, that could be the problem.

Even if you’re feeding your cat a high-quality cat food, he might be having trouble digesting one of the ingredients. Food allergies and sensitivities can happen in cats as well as people, so if your cat suddenly develops foul-smelling stool, you might take a look at his diet. To diagnose and treat food allergies, it’s a good idea to switch to a limited ingredient diet (LID) made with a lower number of primary ingredients to reduce the risk for triggering the allergy. It’s also a good idea to feed your cat a novel (new) protein source like duck, rabbit, or venison. After 12 weeks, if your cat’s symptoms have resolved, then you know it was his diet that was the problem.

In addition to identifying specific problems with your cat’s diet, there are some general things you should look for in a cat food to reduce litter box odor. Here are some things to look for in cat food for smelly poop:

  • High-quality animal protein. Your cat requires a minimum of 26% protein in his diet, and it is best when it comes from animal sources like chicken, fish, and meat. A high-quality animal protein should be the first ingredient, and more protein is always better than less.
  • Healthy animal-based fats. Fats provide a concentrated source of energy for cats as well as support for healthy skin and coat. They are best from animal sources like chicken fat and salmon oil, but plant-based fats can be used as supplemental sources.
  • Digestible carbohydrates. When it comes to litter box odor, digestibility is key – if your cat has trouble digesting his food, his poop will smell more. Some cats are able to digest whole-grain carbohydrates, but you should still limit the amount of carbohydrate in your cat’s diet.
  • Limited number of ingredients. The shorter the ingredients list, the lower the potential for triggering food allergies which can cause digestive symptoms like diarrhea and smelly poop.
  • Rich in moisture and fiber. Increasing the moisture and fiber content of your cat’s diet will help boost his digestion which will hopefully reduce the odor in the litter box.
  • No artificial additives. Artificial colors, flavors, and preservatives all have the potential to upset your cat’s stomach which can lead to digestive symptoms like smelly poop.

Now that you have a better understanding of what to look for in the best cat food to control feces odor, you’re ready to start shopping! If you’re still not sure where to look, try one of our top picks reviewed in the next section.

Frequently Asked Questions

  • Why does cat feces smell so bad? – It is just a fact of life that cat poop smells horrible, but if your cat’s feces starts to smell more foul than usual, it may be an indication of a problem. Intestinal parasites, bacterial infection, and digestive disorders can all cause diarrhea, gas, and foul-smelling stools. Talk to your veterinarian and have a stool sample tested to make sure your cat isn’t sick.
  • Does wet food make a cat’s poop smell? – It is not a matter of dry food versus wet food when it comes to foul-smelling feces but rather a matter of ingredients. Ingredients that are hard for cats to digest (like grains and fillers) are likely to cause smelly poop, regardless of it being dry food or wet food. Actually, wet food tends to be lower in carbohydrate ingredients than dry food on the whole, but low-quality wet food can be just as difficult for your cat to digest as low-quality dry food.
  • What would cause my cat to have diarrhea? – Occasional diarrhea in cats can be caused by any number of things ranging from a change in diet to bacterial infection. Diarrhea is often a sign that your cat’s digestive system is upset and that can be caused by something he ate or something he was exposed to. Intestinal parasites, bacterial infections, and digestive disorders can all have diarrhea as a symptom, or it could simply be that your cat’s body is having trouble properly digesting something he ate.
  • What gets rid of the smell of cat poop? – You can’t completely get rid of the smell of cat poop, but there are certain things you can do to make your cat’s stools smell less. Improving the quality and digestibility of his diet is key – if his body is able to digest the food and absorb the nutrients, there will be less waste, and his digestive system will be less irritated. If your cat is suffering from a bacterial or parasite infection, treating that issue is the best way to resolve litter box odor. If you’re not sure what’s cause your cat’s poop to smell, the best thing you can do is talk to your veterinarian.

The quality of your cat’s diet always matters, but if you’re trying to get rid of foul-smelling tools, it is even more important. The higher the quality of your cat’s food, the more digestible it will be. When your cat’s digestion is healthy, you won’t have to worry about issues with smelly poop.
