Being pet parents, we all love to play with our little furry friends, but when it comes to their smelly stools, we all hate the smell. And particularly if the smell is so awful that it stays after hours of cleaning the litter box.

But what makes a cat's excrement smelly? Intestinal parasites, bacterial infections, digestive problems, or an unpleasant diet are frequently to blame.

To be sure your cat isn't sick, you should take them to the vet before doing anything else. Altering their food is your greatest option if they're not sick.

But why alter their meal? Your cat may have formed an allergy to specific foods, such as wheat and another protein source like chicken and fish, or it could simply be having difficulties digesting some ingredients. All of these could result in excessively stinking poop.

Which food, though, would be most beneficial?

We've examined some of the most well-liked cat foods for smelly cat poop and created a list that may cover the problem of stinky poop.

Points to Ponder When Buying the Best Cat Food for Smelly Poop

The first thing you should consider when selecting a new food for your cat is the ingredients list. The following ingredients should always be present in food:

1. Balanced Nutrition:

A good supply of animal protein since cats are carnivores and need protein to meet a significant portion of their nutritional demands. In reality, no less than 26% of their meals should contain protein as a minimum. This protein should be the first food item and should come from a high-quality animal source, like fish, chicken, turkey, etc. Moreover, you should also look for farm-raised chicken as a source of protein in the food.

2. Limited Ingredients Food:

Allergies in cats or digestive problems will do better if their chow contains fewer components. Cat foods with limited ingredient cat food typically have fewer components than usual. And that can help to avoid the unneeded substances that lead to allergic response.

3. Healthy fats:

Cats require a diet high in good fats (about 20–24%) such as omega-6 fatty acids and high protein levels. You would believe that eating foods with more fatty acids will make cats gain weight, but in reality, if a food doesn't satisfy your pet's needs for omega fatty acids, they will consume more than they should. Additionally, animal-based fats like salmon oil and chicken fat must be consumed. Moreover, such fats can be supplemented with plant fats as well. In fact, you should give your cat quality nutrition.

4. Increased moisture:

Cats usually don't drink as much water as they ought to. Some believe this is a holdover from felines' primal habits when they would obtain most of the water they required from prey. However, a cat's body is largely composed of water, just like ours, so they must get what they need. They can achieve their goal by eating more moisture-rich foods, and drinking more water will also aid digestion.

5. Healthy fibers:

A cat food's fiber level need not be very substantial, but it should come from a reliable source, such as beet pulp or pea protein. Like humans, a source of fiber in food can improve your cat's digestion and produce less foul-smelling stools.

6. Carbohydrates that are simple to digest

Digestion is frequently a factor in the problem of getting rid of foul-smelling stools. It will help greatly if you feed your cat food that is simple to digest and have limited ingredient diets. Choose a meal containing carbs from sources other than whole grains because some cats may have no trouble digesting them while others may struggle greatly.

Why Does the Cat Poop Stinks?

The following factors can make your cat's poop smell highly awful:

1. Diet

Your cat may have unpleasant-smelling feces if its diet is unbalanced or difficult for them to digest.

2. Bowel inflammation disease

Food allergies frequently contribute to such health issues. Beef, fish, and chicken sensitivities are the most prevalent. Sometimes cats experience intestinal inflammation without being allergic, resulting in problems with stool in cats.

3. Parasites

Roundworms and coccidia are just two of the many parasites that are typical to outdoor-living adult cats and kittens. Giardia species and Tritrichomonas species are the parasites most likely to disturb a cat's digestive system. To eradicate these parasites, specialized testing and protracted treatment regimens are necessary.

4. Diseases of the liver or gallbladder

The liver produces bile and nutrients and filters toxins as a digestive system component. The gallbladder is crucial for assisting with meal fat digestion. A cat's excrement may smell foul if it has liver or gallbladder illness.

5. Pancreatic illness

The digestive system includes the pancreas, which supplies the enzymes required to break down food and absorb nutrients. Some cats get pancreatitis or persistent pancreatic inflammation. Rarely a cat's pancreas may become so scarred that it is completely useless.

6. Medications

Antibiotics, for example, can disturb healthy intestinal bacteria. The intestinal health of cats is impacted when aberrant bacteria take control after the usual bacteria are eliminated. This may result in unpleasant cat feces.

7. Stress

Because a cat's hormones vary under stress, stress can upset the stomach. Stress can alter a cat's intestinal health if it is a one-time occurrence (like moving to a new house) or ongoing stress (such as being picked on by a second cat).

8. Other ailments

Any sickness causes stress in cats because it causes them pain or suffering. Although some ailments are not necessarily related to the health of the cat's stomach, being ill generally might impact the gut.


There are numerous alternatives available for cats with sensitive stomachs and foul-smelling stools. Smalls Human-Grade Fresh Food is the greatest choice for smelly cat poop. Your cat is less inclined to react because it is produced using unique proteins.

We suggest Purina ONE Tender Selects Blend Dry Cat Food as a less expensive choice. Even though it is far less costly than other possibilities, the initial component is still chicken. It is tasty. Therefore fussy cats might be able to eat it.
