Because it’s a raw food made primarily made from ultra-digestible animal ingredients, we recommend Stella & Chewy’s Chick Chick Chicken as the overall best cat food for smelly poop. Multiple customers mention a change in fecal odor after switching to this food, with reviewers saying that their cats’ poop “no longer stinks!” and that it’s “not stinky like with wet food”.

But this food isn’t right for everyone. To help you find the recipe that works for you, we’ve recommended a total of 7 top recipes. Each brings something a little different to your cat’s bowl, but all of them have the same combination of digestion-friendly qualities.

Before we get into the reviews, let’s talk about what sets the best cat food for smelly poop apart from the crowd.

What are the qualities of the best cat food for smelly poop?

With various health issues potentially contributing to severe fecal odor, ruling out infections and other health issues is essential before you start dietary odor management.

Once you’ve established that diet is the solution, prioritize two things: simplicity and efficiency.

All poop smells, but it smells worse when there’s more to it—more sulfur, more bacteria, and more digestive by-products. Time also plays a part. Foods that take longer to digest spend more time in the GI tract, giving digestive gases more time to build up and make your cat’s litter box session all the smellier.

By keeping things simple, the best cat food for smelly poop minimizes the amount of work your cat’s body does to process his food, making digestion more efficient.

What does that mean when you’re shopping for food? Let’s go into a little more detail.

The best cat food for smelly poop is free of allergenic or irritating ingredients.

In addition to other symptoms, food allergies may cause flatulence and reeking stool. Cats can develop allergies to almost any protein—the most common culprits are the ones they eat the most. For that reason, the most common cat food allergens include chicken, seafood, beef, dairy, wheat, corn, and soy.

Though the idea of an allergic pet is hot right now, true food allergies—an inappropriate immune reaction to dietary proteins—are rare among cats.

Instead, many cats experience unexplained food intolerances. Whether you suspect that your cat has intolerances or allergies, a stripped-down diet can help to avoid anything that irritates him. Look for foods with a single protein source—this helps to minimize your cat’s exposure to anything that might trigger an allergic response—and steer clear of the most common irritants.

And don’t be limited by the “limited-ingredient diet” label. In spite of the name, they’re often loaded with an army of unnecessary ingredients and may even contain multiple protein sources. Read the ingredient list and pick recipes with a single protein source and no more than 4 main ingredients.

The best cat food for smelly poop is free of lactose.

Most adult cats are lactose-intolerant, potentially leading to digestive distress and smelly poop. Avoid giving your cat cow’s milk as a treat and pass up foods that contain it.

Raw cat food appears to be a powerful solution for smelly poop.

Many people insist that switching to a raw diet gives their cats drier, smaller, and less smelly poop.

For example, Reddit user “iwasbornsick” has a unique perspective on the topic. In a discussion on pet food, this Reddit user explains that they live with five cats owned by three different people, each of whom feeds a different type of diet:

“My cat eats raw and high quality canned food; his poo is solid, small, and only stinky for about 5 minutes. Two cats are fed a fairly high quality dry kibble; their poo is more voluminous than mine, and much stinkier, but eventually it dissipates. The last two eat low quality dry kibble, and their poo is very, very stinky.”

So what makes raw cat food different and what does that have to do with the smell in your cat’s litter box?

Digestibility appears to be the key difference between raw cat food and other products. Because raw food is typically composed of high-value animal parts and not much else, they honor your cat’s nutritional needs without creating a lot of waste.

The best cat food for smelly poop is high-quality and easy to digest.

Protein digestibility is a question mark in the feline nutrition world. While we’ve mapped out the biological value (a measure of the percentage of protein the body uses when it takes in a given food) of proteins for humans, we just don’t know exactly which protein sources are most and least biologically available to cats.

That said, we do know that cats are obligate carnivores, capable of thriving on a diet of nothing but small animals. It appears that meat is the most efficient source of protein for your carnivore.

First 5 Ingredients: Chicken, Dried Egg Product, Pork Protein Isolate, Gelatin, Chicken Fat (Preserved With Mixed Tocopherols)

Compared to canned and raw cat food, kibble tends to have the worst effects on litter box odor. Most dry foods are starchy, contain lower-efficiency protein sources, and have more fiber than your cat needs.

All of this adds up to bulkier, smellier poop and, in most cases, a less-healthy cat.

While nothing can replace the moisture content of a wet, raw, or fresh-cooked diet, this dry food manages to avoid most of the flaws of your traditional kibble. It’s a high-protein food primarily made from animal-derived ingredients. With an emphasis on protein digestibility, this food promises to nourish your cat without bulking up his waste or weighing him down in any way.

Thanks to the use of gelatin instead of potatoes, grains, and other starchy ingredients, the food is a low-carbohydrate and generally species-appropriate option.

Ingredients:

Chicken, Chicken Broth, Chicken Liver, Dried Egg Product, Natural Flavor, Salmon Oil, Agar-Agar, Tricalcium Phosphate, Barley Grass, Choline Chloride, Potassium Chloride, Salt, Taurine, Turmeric, Dried New Zealand Green Mussels, Zinc Proteinate, Iron Proteinate, Magnesium Proteinate, Niacin Supplement, Vitamin E Supplement, Copper Proteinate, Sodium Selenite, Thiamine Mononitrate, Manganese Proteinate, Vitamin A Supplement, Calcium Pantothenate, Riboflavin Supplement, Pyridoxine Hydrochloride, Biotin, Vitamin D3 Supplement, Vitamin B12 Supplement, Ethylenediamine Dihydroiodide, Folic Acid.

What We Didn’t Like:

First 5 Ingredients: Chicken, Chicken Broth, Sunflower Seed Oil, Tricalcium Phosphate, Taurine

If your cat needs to lose weight, a lean, high-protein, moisture-rich diet like this food from Tiki Cat can help.

The food contains nothing but shredded chicken in a fortified broth with sunflower seed oil as its main fat source. The food’s straightforward recipe minimizes your cat’s exposure to irritants while keeping calorie content low. It’s also an extremely low-carbohydrate, low-fiber food.

Note that this low fiber content isn’t ideal for digestive health. You might want to supplement this food with a probiotic supplement and a source of fiber. A bowl of cat grass can make a big difference.

Ingredients:

Chicken, Chicken Broth, Sunflower Seed Oil, Tricalcium Phosphate, Taurine, Choline Chloride, Potassium Chloride, Sodium Chloride, Magnesium Sulfate, Zinc Amino Acid Chelate, Iron Amino Acid Chelate, Vitamin E Supplement, Ascorbic Acid, Thiamine Mononitrate (Vitamin B1), Niacin (Vitamin B3), Manganese Amino Acid Chelate, Vitamin A Supplement, Copper Amino Acid Chelate, Calcium Iodate, Calcium Pantothenate, Sodium Selenite, Riboflavin Supplement (Vitamin B2), Vitamin B12 Supplement, Pyridoxine Hydrochloride (Vitamin B6), Folic Acid, Vitamin D3 Supplement, Biotin, Vitamin K3 Supplement.

First 5 Ingredients: Finely Ground Whole Rabbit, Rabbit Heart, Rabbit Liver, Rabbit Lungs, Rabbit Kidney

Freeze-dried raw foods are among the best options for cats with smelly poop. For those who also have digestive sensitivities, those diets are all the better when they have limited ingredient lists and single protein sources.

Remember—food isn’t always the solution. Sometimes more serious issues are at play.

Many times, simply changing out what your cat is eating can be enough to fix the smelly poop problem, but it’s a good idea to talk to your vet to see if the problem is more severe than just a poor diet.

Other, more dangerous factors can contribute to seriously smelly poop:

  • Spoiled food. If your cat eats something rotten—maybe something straight from the garbage—his poop might temporarily smell worse than usual.
  • Tapeworms and other parasites. Intestinal parasites cause a variety of digestive issues, including severe fecal odor. Giardia, for example, is an intestinal parasite that causes foul fecal odor.
  • Constipation. If there’s a blockage in your cat’s colon, it can cause poop and gas to smell awful.
  • Digestive disorders. If your cat has a digestive disorder that impedes nutrient absorption, it can cause your cat’s poop to smell foul.
  • Drugs. Antibiotics and certain other drugs can contribute to severe fecal odor.
  • Infections. Certain types of infections can cause similar digestive issues, including smelly poop. Bacterial infections of E.coli and salmonella cause inflammation, leading to diarrhea and gas, both of which can have an unusually intense odor.

What Is Causing Your Cat’s Poop to Smell

We touched on a few of the things that could be fouling your cat’s poop, but let’s get you a more detailed list of them so that you know what to watch out for:

  • Spoiled food- When your cat eats food that is expired, filled with bacteria or something straight from the garbage, then the cat’s poop is probably going to smell
  • Tapeworms and other parasites- Stomach parasites not only make your cat’s poop smell but also damage your cat’s body over time
  • Constipation– If there is some blockage in your cat’s colon, it can cause poop and gas to smell awful
  • Digestive disorders– Unabsorbed starch and other digestive problems can cause your cat’s poop to smell foul
  • Drugs– If your cat is taking some medications, those may be causing the problem, and if those drugs are causing hormonal changes, then that could be to blame for the smelly poop as well
  • Infections– Certain types of infections can cause a similar problem as well

The Benefits of Buying Grain Free, Hypoallergenic and limited ingredient Cat Food

Some vets are going to recommend that you switch your cat’s diet to something that is grain free and hypoallergenic in other words, specifically targeted to combat food allergies.

Here are the benefits you and your cat will enjoy by choosing this food over commercial cat food.

  • Cuts back on allergy risks– Even if your cat is not having allergy issues with the food it is eating, switching to a hypoallergenic cat food will reduce the risk that there will be allergy symptoms in the future
  • Provides a healthier and more balanced diet– Grain free, hypoallergenic food tends to be very healthy and packed with nutrients of all kinds
  • Helps poop smell better– If your cat is having smelly poop, then giving your cat a grain free meal can make a huge difference there
  • Improves food tolerance– Most hypoallergenic cat foods contain little to no dairy, which is a major source of food intolerance in cats
  • Makes cats feel better- Cats have more sensitive noses than we do, and if they don’t have to smell their stinky poop anymore, then they will be happier and feel better.

Overview

If you notice that your cat’s poop smells extra bad, then you should start by contacting a veterinarian first.

Ask a Vet

vet If your cat is exhibiting labored, rapid, or noisy breathing, you’ll need an expert to help you identify what’s going on and how to fix it. If you can’t bring your cat to a veterinarian right now you may want to contact a vet on JustAnswer. For between $10 and $100, this service allows you to connect one-on-one with a real veterinarian in real time. It’s one of the best ways to get personalized expert advice at a fraction of the cost of a vet visit.

Ask A Question

ASK A QUESTION

Your vet can help you determine what the cause of the smelly poop is and what you need to do to fix the problem. If your cat only has this issue for a day or two, then it may not be something that you need to concern yourself with, but if it persists or it keeps coming back, then you will need to do something about it.

Often, a diet change is all your cat needs to start feeling better and to start having better smelling poop.

Be sure to consult with your veterinarian about any major changes you are making to your cat’s lifestyle and diet, especially if your cat is being treated for a medical condition.
We hope that you can use the information here to get your cat healthy once more and to get rid of that foul poop smell.
