What Causes Smelly Poop?

Your cat’s poop will always smell, but if you notice a change in odor it could be a problem with its diet. Cat foods made with low-quality fillers, thickening agents, dairy products, and allergens are more likely to make your cat’s poop smell.

Smelly poop could also be an indication that your cat’s body is having a hard time digesting the food which may be due to a high concentration of plant ingredients.

Some of the common causes of smelly poop are as follows:

Diet: If your cat is sensitive to a certain ingredient in her diet such as grain, it may cause smelly poop. In such cases, a limited ingredient or hypoallergenic diet may work. You can also try eliminating one ingredient at a time to find the offending ingredient.

Cat food made with low-quality fillers, and dairy products can also make your cat’s poop smell. Thickening agents such as guar gum and agar agar found in canned cat foods can cause litter odors as well. Being natural hunters, cats tend to snack on bugs, reptiles, and rodents, which can cause foul smelling poop. Another surprising culprit is vitamin supplements.

Bacteria: Bacteria such as E.coli and Salmonella can cause inflammation and lead to foul smelling gas and diarrhea in cats. Parasites: Intestinal parasites such as Giardia can cause smelly poop, flatulence, and diarrhea in cats. Regular de-worming can protect your cat from a parasitic infection.

Digestive Disorders: Digestive disorders in cats can result in smelly poop. Undigested fats and starches can lead to digestive problem such as rancid smelling stools.

Anal Gland Infection: Cats have anal glands, which can become infected. This can cause smelly poop and can also be painful for your cat. A vet will draw out the infected element and treat the condition with antibiotics.

Medication: Certain medications such as hormone-altering and pain medicines can cause smelly poop in cats. Dr. Mike Paul at Pet’s Health Network has a guide about cats’ smelly poop here.

Here are some things to look for in a cat food for smelly poop:

  • Animal Ingredients. As a carnivore, your cat is better able to digest animal than plant ingredients. A diet too high in plant-sourced ingredients can cause smelly poop.
  • Digestibility. If your cat’s body is having trouble digesting its food, its poop is more likely to be smelly. Look for animal sources of protein and fat with low levels of carbohydrate.
  • No Fillers or Additives. Low-quality fillers like corn and wheat are common causes for smelly poop, as are artificial additives and thickening agents like agar-agar and guar gum.
  • Hypoallergenic. Because food allergies are one of the most common causes of smelly poop in cats, you may want to choose a limited ingredient diet or a food made with a novel source of protein to reduce the risk for allergies.

Keeping all of these things in mind, you’re now ready to learn how to choose the best cat food for smelly poop. Here’s what you need to know:

How To Choose The Best Cat Food For Smelly Poop?

Your cat is an obligate carnivore. What this means is that its body is able to digest and utilize nutrients from animal sources more efficiently than from plant sources.

Protein and fat are the two most important nutrients for your cat, and they should both come from animal sources. Plant sources can sometimes be used for supplemental protein or fat, but they shouldn’t appear at the top of the list.

The best proteins for your cat are meat, poultry, and fish. Animal proteins are complete proteins which means that they contain all of the essential amino acids your cat needs.

Fat provides a concentrated source of energy in the form of calories and it also provides the omega fatty acids your cat needs for healthy skin and coat. Your cat requires a minimum of 26% protein in its diet and 9% fat.

In addition to protein and fat, most cat foods contain some carbohydrate ingredients like grains and vegetables. Unfortunately, plant ingredients are more difficult for your cat’s body to digest which can contribute to smelly poop.

For the best results, choose a grain-free recipe made with limited carbohydrate content and fortified with probiotics to support healthy digestion.

Keep reading to see our top 8 recommendations for the best cat food for smelly poop.

The Benefits of Hypoallergenic Cat Food

The term “hypoallergenic” simply means that the product in question has a low risk for triggering an allergic reaction.

Because cats can develop allergies to any food ingredient, this means that the term hypoallergenic applies in a variety of different situations – a cat food that is hypoallergenic for one cat might not be for another cat.

It all depends on the ingredient your cat is allergic to.

In terms of the benefits of hypoallergenic cat food, there are several worth mentioning.

The first is, of course, that the food has a lower risk of triggering your cat’s allergy. Second, most hypoallergenic cat foods are made with high-quality natural ingredients.

Many cat foods in this category are made with uncommon sources of animal protein like venison or lamb to further reduce the risk of triggering an allergy, and they often have beneficial supplements to support healthy digestion and nutrient absorption.

Hypoallergenic cat foods come in a variety of formulas to suit your cat’s individual needs.

Choosing Cat Food For Allergies And Sensitivities

If you know that your cat has an allergy or sensitivity to a specific ingredient and you suspect that this problem is the cause for its smelly poop, the best thing to do is choose a cat food that doesn’t contain that ingredient.

Look for a limited ingredient diet that has a low number of main ingredients to reduce the risk for triggering your cat’s allergy or sensitivity.

You should also consider a cat food made with a novel source of protein – one it hasn’t eaten before, especially if your cat’s allergy is to a protein like beef, pork, chicken, or fish.

Final Remarks

Though you can’t expect your cat’s poop to ever smell nice, making changes to its diet could resolve issues with particularly smelly poop.

The best cat food for smelly poop is made from high-quality animal proteins, healthy animal fats, with low levels of digestible carbohydrates.
