How We Tested
We personally purchased and tested the products on this list. The entire testing process was funded by Cats.com without direct input or influence from the companies involved.
When researching cat food, we analyze the information on the label including the guaranteed analysis, list of ingredients, and life stage designation. We also consult customer reviews for insight regarding reformulations or issues with product quality and check for product recalls.
During our in-depth testing, we make observations about the product’s appearance, texture, consistency, smell, and packaging. We also feed the food to our cats to get their opinion regarding palatability and general appeal.
In addition to performing our own qualitative analysis of the brands reviewed here, we submitted samples of several recipes for analysis at an ISO 17025 certified food testing and analysis lab.
Analytical testing in a food chemistry lab gives us the exact macronutrient and micronutrient content of each recipe. The tests also look at microbial content, yeast, mold, and heavy metals, helping you ensure that you’re only putting the best in your cat’s bowl.

What Are the Qualities of the Best Cat Food for Smelly Poop?
Changes inside the litter box are often a first-line indicator of underlying health issues. If your cat’s feces has changed in odor, appearance, frequency, or volume, it’s best to consult your veterinarian to rule out infections and other health problems.
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.
The best cat food for smelly poop exhibits the following qualities:
It is rich in species-appropriate animal protein.
Cats are obligate carnivores which means they’ve evolved to follow a meat-based diet. Their digestive tracts are very short because they’re designed to process highly-digestible raw prey – there’s little need for the fermenting bacteria required to digest plant matter.
Species-appropriate food for cats is formulated around animal products like poultry, meat, and fish. Animal-based protein should top the ingredient list, ideally balanced with animal-sourced fat.
The lower the carbohydrate content of your cat’s food, the better. A whole-prey diet for cats contains less than 10% dry matter carbohydrate.
It contains a short list of highly digestible ingredients.
The more ingredients a cat food contains, the more work it is for your cat’s body to digest. A short list of species-appropriate ingredients ensures optimal digestion with less waste, and therefore less odor.
Again, animal ingredients are the most digestible for your cat. Avoid starchy carbohydrates that add bulk to the product without supplying much nutritional value. Peas, lentils, and other legumes should be avoided as well because they contain high levels of lectins and phytates.
Lectins are plant proteins which, when consumed in large quantities, can contribute to gastrointestinal distress. Phytates play a role in leeching essential minerals like calcium and iron from your cat’s body.
It contains plenty of hydrating moisture.
Wild cats get most of their water from prey, so they don’t have high thirst drives. Unfortunately, domestic cats have inherited this trait and many cats don’t get the water they need for proper hydration.
Water is a key ingredient in both urine and feces, and it’s necessary to remove waste products from the body. When your cat isn’t properly hydrated, it can lead to constipation and other health issues. High-moisture cat food helps support your cat’s digestion and may reduce litter box odor.
It is free from allergenic and irritating ingredients.
In addition to other symptoms, food allergies may cause flatulence and smelly stool. The most common food allergies in cats are caused by proteins, primarily chicken, fish, or beef. Other less common cat food allergies include wheat, corn, and soy.
True food allergies are fairly uncommon in cats, and they often manifest with skin-related symptoms like itchy skin and hair loss. If your cat is diagnosed with a food allergy, it’s imperative that you identify the allergen and adjust your cat’s diet to avoid it.
In many cases, switching to a limited ingredient diet made with a single, novel source of protein does the trick. A novel protein is simply one your cat hasn’t eaten before.
Most adult cats are lactose-intolerant, so it’s wise to avoid cat foods that contain dairy as well. Dairy products have the potential to cause 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 Foods for Smelly Poop: Our Top Picks
The following foods emphasize the qualities that we look for in the best cat food for smelly poop.
#1 Overall Best: Smalls Fresh Ground Bird
Smalls is a fresh cat food delivery service that uses human-grade ingredients, including animal 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.
Featuring chicken and chicken liver as the top two ingredients, this fresh food is packed with species-appropriate animal protein. Measured as dry matter, the food contains over 55% protein and 30% fat with under 10% carbohydrate. In addition to being high in protein and low in carbohydrates, this formula is rich in moisture, which helps support digestion and overall health.
While this food is high in protein, fat, and moisture, it does contain some peas and the only source of added fat is plant-based. Multiple customers mention a change in fecal odor after switching to this food, however, with reviewers saying that their cats’ poop “no longer stinks!” and that it’s “not stinky like with wet food”.

#2 Premium Pick: Open Farm Harvest Chicken Freeze-Dried Raw Cat Food
Raw cat food is an excellent option, but it isn’t always the most convenient choice for cat owners. Freeze-dried cat food offers similar nutritional value but, because the moisture has been removed, it can be safely stored at room temperature. That being said, the food should be rehydrated before offering it to your cat, so they get the moisture they need.
This freeze-dried formula from Open Farm features chicken as a single source of protein. Open Farm uses only ethically and sustainably sourced ingredients which, in this case, includes 98% humanely raised, cage-free chicken, chicken liver, chicken necks, and chicken bone.
Though this recipe contains some added carbohydrate in the form of organic dandelion greens, the dry matter carbohydrate content of the food is very low, under 10%.
Ingredients
Chicken with Ground Bone, Chicken Liver, Chicken Neck, Montmorillonite Clay, Organic Dandelion Greens, Potassium Chloride, Choline Chloride, Vitamins (Niacin Supplement, Vitamin E Supplement, Vitamin A Supplement, Thiamine Mononitrate, Pantothenic Acid, Riboflavin Supplement, Pyridoxine Hydrochloride, Vitamin D3 Supplement, Vitamin B12 Supplement, Folic Acid, Biotin) Taurine, Organic Cranberries, Minerals (Zinc Proteinate, Iron Proteinate, Copper Proteinate, Manganese Proteinate, Calcium Iodate, Sodium Selenite) Salt, Salmon Oil, Mixed Tocopherols, Magnesium Sulfate, Rosemary Extract.

#3 Budget Pick: Dave’s Pet Food Naturally Healthy Grain-Free Turkey Formula Canned Cat Food
If you’re looking for a budget-friendly wet cat food, Dave’s Healthy & Delicious canned foods average around $0.25 per ounce when you buy the 12.5-ounce cans in a case of 12. They’re a little higher in carbohydrate than the other foods on this list, but they don’t contain peas, legumes, or starchy fillers like many inexpensive cat foods do.
This recipe features fresh turkey as the primary ingredient with supplemental protein from chicken liver and chicken muscle meat. The only added carbohydrates are sweet potatoes and carrots which contribute to the food’s dry matter carb content of just over 16%.
In addition to being a high-moisture canned food, this recipe contains about 45% dry matter protein and nearly 23% fat. The short list of ingredients makes it highly digestible, though some cats experience loose stools after eating foods thickened with guar gum.
Ingredients
Turkey, Chicken Broth, Chicken Liver, Chicken, Guar Gum, Sweet Potatoes, Carrots, Agar-Agar, Potassium Chloride, Salt, Minerals (Iron Proteinate, Zinc Proteinate, Copper Proteinate, Manganese Proteinate, Sodium Selenite, Potassium Iodide), Choline Chloride, Vitamins (Vitamin E Supplement, Thiamine Mononitrate, Niacin Supplement, D-Calcium Pantothenate, Pyridoxine Hydrochloride, Riboflavin Supplement, Vitamin A Supplement, Biotin, Vitamin D3 Supplement, Vitamin B12 Supplement, Folic Acid), Cranberries, Blueberries, Taurine, Dried Squash, Zucchini, Sodium Carbonate.

#4 Best Wet Food: RAWZ 96% Turkey & Turkey Liver Pate Canned Cat Food
Packed with species-appropriate animal protein and hydrating moisture, RAWZ wet food is a highly digestible option. This recipe is comprised of 96% turkey muscle meat and turkey liver. The dry matter protein content is nearly 41% while the carb content is low, about 8.5% dry matter.
Aside from the turkey and turkey liver, the only other ingredients in this food are the turkey broth which supplies moisture, fenugreek seed as an alternative to gum thickeners, and dandelion greens as a source of calcium and potassium.
The downside of this food is the price tag – it costs about $0.60 per ounce. At 37 calories per ounce, however, it’s a calorie-dense food, so your cat may need less of it than other foods. Plus, 100% of the proceeds from sales of this food go to the RAWZ foundation which helps provide service dogs to individuals recovering from spinal cord and traumatic brain injuries.
Ingredients
Turkey, Turkey Liver, Turkey Broth, Fenugreek Seeds, Dandelion Greens, Taurine, Natural Flavor, Potassium Chloride, Choline Chloride, Magnesium Proteinate, Zinc Proteinate, Iron Proteinate, Niacin Supplement, Vitamin E Supplement, Copper Proteinate, Sodium Selenite, Calcium Iodate, Thiamine Mononitrate, Manganese Proteinate, Vitamin A Supplement, Calcium Pantothenate, Riboflavin Supplement, Pyridoxine Hydrochloride, Salt, Biotin, Vitamin D3 Supplement, Vitamin B12 Supplement, Folic Acid.

#5 Best Dry Cat Food: Dr. Elsey’s cleanprotein Chicken Formula Grain-Free Dry Cat Food
Compared to canned and raw cat food, kibble tends to have a more significant effect 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. The sample we sent for lab testing contained even more protein and less carbohydrate than the values listed in the guaranteed analysis.
Ingredients
Chicken, Dried Egg Product, Pork Protein Isolate, Gelatin, Chicken Fat (Preserved With Mixed Tocopherols), Flaxseed, Natural Flavor, Salmon Oil, Potassium Citrate, Calcium Carbonate, Fructooligosaccharide, Calcium Carbonate, Choline Chloride, Vitamins (Vitamin E Supplement, Niacin Supplement, D-Calcium Pantothenate, Vitamin A Acetate, Thiamine Mononitrate, Pyridoxine Hydrochloride, Riboflavin Supplement, Vitamin D3 Supplement, Biotin, Vitamin B12 Supplement, Folic Acid), Minerals (Ferrous Sulfate, Zinc Oxide, Calcium Carbonate, Manganous Oxide, Copper Sulfate, Iron Amino Acid Chelate, Manganese Amino Acid Chelate, Zinc Amino Acid Chelate, Copper Amino Acid Chelate, Sodium Selenite, Cobalt Carbonate, Ethylenediamine Dihydroiodide), Potassium Chloride, Mixed Tocopherols (Preservative), Taurine, Salt, Rosemary Extract.

#6 Best For Weight Loss: Tiki Cat Puka Puka Luau Succulent Chicken in Chicken Consomme
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.

#7 Best Novel Protein: Vital Essentials Rabbit Freeze-Dried Dinner Patties
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.
Ingredients
Rabbit, Rabbit Liver, Rabbit Heart, Rabbit Kidney, Rabbit Lung, Herring Oil, Mixed Tocopherols (Preservative), Vitamin E Supplement, Zinc Amino Acid Complex, Iron Amino Acid Complex, Copper Amino Acid Complex, Manganese Amino Acid Complex.

#8 Best For Sensitive Stomachs: Raised Right Turkey & Pumpkin Pate For Adult Cats
Raised Right Turkey & Pumpkin Pâté for Adult Cats is free of ingredients and additives that might worsen or cause smelly poop. It doesn’t contain any animal by-products or rendered meals. Instead, it’s primarily made from readily digestible animal ingredients like turkey thigh, heart, and liver.
While this cat food is formulated for easy digestibility, some cats dislike the flavor or texture of it. It’s also worth noting that you can only purchase it in two quantities – a four-pack or 16-pack of 1-pound bags.
Each batch of cat food is made-to-order in the company’s own kitchen. Because it’s fresh, moisture-rich, and full of species-appropriate animal protein, this food is an easily digestible option for many cats and could be a good choice for those with sensitive stomachs.

#9 Best For Kittens: Wellness CORE Kitten Turkey & Chicken Liver Pate
Smelly stool is a frequent problem for kittens. Intestinal parasites are common, especially in kittens who’ve spent time in a shelter, and the transition from their mother’s milk to commercial cat food can contribute to digestive distress. Feeding your kitten a high-moisture wet food made primarily with animal-sourced ingredients may help minimize odor.
This Wellness CORE formula contains over 54% protein and 34% fat, measured as dry matter. The first six ingredients are animal-based and the formula relies on animal-sourced fat from menhaden fish oil. It’s a calorie-dense food rich to help support growth with plenty of DHA for brain and eye development.
Overall, this recipe is highly digestible for most cats, and it contains less than 10% dry matter carbohydrate. Keep in mind, however, that some cats experience loose stools when eating foods that contain gum thickeners like guar gum.
Ingredients
Turkey, Chicken Liver, Turkey Broth, Chicken, Chicken Meal, Herring, Natural Flavor, Cranberries, Menhaden Fish Oil (preserved with Mixed Tocopherols), Guar Gum, Tricalcium Phosphate, Ground Flaxseed, Potassium Chloride, Choline Chloride, Taurine, Cassia Gum, Xanthan Gum, Dried Kelp, Chicory Root Extract, Yucca Schidigera Extract, Alfalfa Meal, Salt, Magnesium Sulfate, Iron Proteinate, Zinc Proteinate, Thiamine Mononitrate, Vitamin E Supplement, Copper Proteinate, Manganese Proteinate, Sodium Selenite, Niacin, d-Calcium Pantothenate, Pyridoxine Hydrochloride, Riboflavin Supplement, Vitamin A Supplement, Biotin, Potassium Iodide, Vitamin D3 Supplement, Vitamin B12 Supplement, Folic Acid, Rosemary Extract.

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.
