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 and your veterinarian have established that diet is the solution to your cat’s smelly poop, 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 gastrointestinal (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. The most common food allergies in cats are caused by a protein, primarily chicken, fish, or beef. Other less common cat food allergies are wheat, corn, and soy.
Though the idea of an allergic pet is hot right now, true food allergies—an inappropriate immune reaction to a certain food—are rare among cats.
Instead, many cats experience unexplained food intolerances. Food intolerances involve only the digestive system, not the immune system. For example, a food intolerance may cause a cat to have diarrhea. Your veterinarian can help you determine whether your cat has a food intolerance or food allergy.
A food elimination trial is the ideal way to determine which food is causing the allergy or intolerance. Your vet will advise you on which diet to feed your cat during this trial, which takes about 8 to 12 weeks.
Once you’ve identified the food to avoid, look for diets that are free of the ‘culprit’ food and contain a single protein source—this helps to minimize your cat’s exposure to anything that might trigger an allergic response. It’s also advisable to feed your cat a novel protein source, such as kangaroo, that is unlikely to trigger a food allergy.
And don’t be limited by the “limited-ingredient diet” or “hypoallergenic” label. In spite of the name, these foods are often loaded with an army of unnecessary ingredients, and may even contain multiple protein sources that could worsen a food allergy or intolerance. 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, flatulence, and smelly poop. Avoid giving your cat cow’s milk as a treat and pass up foods that contain it.
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.
In addition to performing our own qualitative analysis of the brands reviewed here, we submitted samples for analysis at an ISO 17025 certified food testing and analysis lab.

First 5 Ingredients: Chicken, Chicken liver, Green beans, Peas, Water (sufficient for processing)
Smalls is a fresh cat food delivery service that uses human-grade ingredients, including premium proteins like chicken, turkey, and fish. Choose from minced-style recipes or classic pâté to provide your cat with protein-rich, low-carb cat food formulated for cats in all life stages.
Though Smalls doesn’t portion out your cat’s meals for you, they do provide detailed feeding recommendations according to your cat’s calorie requirements. Each package of food contains about 16 ounces of food, with markings on the package at 50-calorie increments.
Smalls cat food is delivered frozen, so you’ll need to thaw the package overnight in the fridge before feeding. Your subscription will be based on your cat’s calorie needs, and you can adjust it as needed by contacting the customer care team.
In addition to their fresh food, Smalls also offers a selection of freeze-dried cat foods, treats, and meal toppers. They also recently started selling millet and silica cat litter.
Featuring chicken and chicken liver as the top two ingredients, this fresh food is packed with premium animal protein. Green beans, peas, and kale are the only carbohydrate ingredients and they are naturally grain-free and rich in nutrients.
In addition to being high in protein and low in carbohydrates, this formula is rich in moisture, which helps support digestion and skin and coat health. Overall, this minced chicken recipe is a high-quality source of balanced nutrition for cats in all life stages.
While Smalls is one of our favorite fresh cat food companies, we’d like to note that they’ve had some issues of late. In addition to a voluntary recall on several of their fresh food formulas, Smalls has had numerous customer service complaints. They claim to be working on the issues, but it’s hard to say when or if they will be remedied.
Ingredients:
Chicken, Chicken liver, Green beans, Peas, Water (sufficient for processing), Chicken hearts, Kale, Tricalcium phosphate, Canola oil, Choline chloride, Potassium chloride, Salt, Taurine, Magnesium Sulfate, Niacinamide, Ferrous sulfate, Zinc sulfate, Vitamin E supplement, Thiamine mononitrate (vitamin B1), Calcium pantothenate (vitamin B5), Copper sulfate, Pyridoxine hydrochloride (vitamin B6), Manganese sulfate, Riboflavin (vitamin B2), Potassium iodide, Folic acid, Biotin (vitamin B7), Vitamin B12 supplement, Vitamin D3 supplement

Enter “AAC20” To Get 20% Off Your First Auto-Ship Order

Turkey broth provides moisture and may help support healthy digestion.
In addition to being rich in animal protein, this formula is completely free from fillers, animal by-products, and vaguely named ingredients, as well as the artificial additives that often contribute to litter box odor. It contains more plant ingredients than we’d like, but the dry matter carbohydrate content of the formula as a whole is still fairly low.

This freeze-dried formula from Stella & Chewy’s addresses the issue of smelly stools in several critical ways. As a high-protein freeze-dried raw food, it relies heavily on the nutritional value of fresh meat.

#6 Best Dry Food: Dr. Elsey’s cleanprotein Chicken Formula Grain-Free Dry Cat Food Review
Read Our Full Brand Review View Lab Report
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 can add up to bulkier, smellier poop.
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.

#7 Best For Weight Loss: Tiki Cat Puka Puka Luau Succulent Chicken in Chicken Consomme Review
Read Our Full Brand Review View Lab Report
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 may be able to help.
This wet food contains nothing but shredded chicken in a fortified broth, with sunflower seed oil as its main fat source. The food’s straightforward recipe, which features natural ingredients, minimizes your cat’s exposure to irritants while keeping calorie content low. It’s also an extremely low-carbohydrate, low-fiber food.
We should note that the low fiber content of this food may not be ideal for cats struggling with diarrhea. In that case, you might want to supplement this food with a probiotic and an added source of fiber. A bowl of cat grass can make a big difference to your cat’s digestive system. Talk with your veterinarian before supplementing your cat’s diet.
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.

#8 Best For Sensitive Stomach: Vital Essentials Rabbit Dinner Patties Review
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.
This food from Vital Essentials features rabbit as its only protein source. With whole rabbit, heart, liver, lungs, kidney, trachea, and blood among its main ingredients, the food manages to deliver the nutrition your cat needs without using a lot of additives that might irritate his digestion.
In addition to its single protein source, the food contains a couple of ingredients with potential health benefits. Herring oil is a well-respected source of omega-3 fatty acids and may help to ease inflammation, while raw goat’s milk has a less-established but promising history of supporting healthy digestion.

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 first 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 a foul fecal odor.
- 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 from E.coli and Salmonella cause inflammation, leading to diarrhea and gas, both of which can have an unusually intense odor.
If increased litter box odor is a new problem and you haven’t recently made any changes to your cat’s diet, talk to your veterinarian to determine whether an underlying health problem might be at play.
Ask a 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
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 has had this issue for only a day or two, then it may not be something you need to concern yourself with, but if it persists or keeps coming back, then you will need to take action.
Often, a change of diet is all your cat needs to start feeling better and 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.
