Best cat food for smelly poop. Greetings, fellow cat owners! Have you ever been in the unfortunate situation of having a stinky surprise left for you in the litter box? If so, you’ve come to the right place. In this blog, we’ll discuss a few of the best cat food options out there that can help reduce smelly poop and make your life a little bit easier. From wet food to dry food, we’ll cover it all.

Smelly Cat Poop

Cats are prone to many gastrointestinal issues, but one of the most persistent problems is smelly cat poop. A common source of smelly cat poop is an imbalance between gastrointestinal bacteria, like Saccharomyces Boulardii, a type of yeast naturally found in the intestinal tracts of cats. An imbalance can occur when a cat’s diet doesn’t provide enough beneficial bacteria to maintain a healthy balance. This can lead to increased levels of ammonia, sulfur-producing bacteria, and other by-products that contribute to foul-smelling stools.

The first step in reducing smelly cat poop is finding the right food for your pet. All cats require proper nutrition for their overall health, but some cats may need special dietary considerations depending on their age, activity level, and health status. Generally, quality commercial dog foods are best for cats because they contain more essential vitamins and minerals than other food types.

Commercial cat food should also be high in animal protein sources like poultry or fish as opposed to plant proteins like corn or soy, which have been linked to digestive issues in some cats. To further reduce unpleasant odors from your pet’s waste, look for diets that are high in prebiotic fibers, as these can help promote beneficial bacteria while minimizing odor-causing bacterial growth.

The key to reducing smelly cat poop is finding the right balance between probiotics and prebiotics that promotes healthy digestion without resulting in odor issues. Most importantly, though? Please work with your veterinarian so they can help guide you toward the best diet choices specific to your individual cat’s needs.

Causes of Smelly Poop

Causes of Smelly Poop

Smelly poop can be caused by a number of different factors, from dietary choices to medical conditions. Some causes may require medical attention, while others can be rectified with changes in diet or lifestyle. It is important to understand the potential causes of smelly poop so that it can be properly treated.

Dietary Causes:

An inadequate or improper diet is often the root cause of smelly poop. Diets low in fiber and rich in fat are more likely to cause foul-smelling stools as the body is unable to break down and absorb these foods properly. Eating overly processed meals high in sodium and preservatives can also lead to an increase in odor-producing bacteria.[1] Dry food formulas may also produce foul-smelling stools due to the high amount of synthetic ingredients and starches that are difficult for cats’ bodies to digest.[2]

Medical Conditions:

Medical conditions such as pancreatitis, liver disease, inflammatory bowel disease, and certain parasites can also cause smelly stools.[3] Contact your veterinarian for assistance if you suspect your cat has any underlying medical condition causing the foul smell.

If your cat’s smelly stools have been linked to their diet, switching them over to quality wet food with high levels of protein and few preservatives can help eliminate the odors.[4] Uncooked meats such as fresh fish or chicken (without bones) will provide beneficial enzymes for proper digestion.[5] It would be best if you also considered adding a natural fiber supplement such as psyllium husk or hemp seed oil into your cat’s dry food meal, which will help reduce odors and improve overall digestion.

The Best Cat Food for Smelly Poop

When it comes to smelly cat poop, nutrition plays a major role. Look for a portion of protein-rich cat food that provides at least 30% of its calories from protein sources. Higher amounts are even better, especially for kittens or cats that are nursing or pregnant. Protein and other essential vitamins and minerals found in high-quality, nutrient-rich cat kibble will help improve digestion, resulting in firmer stools with fewer odors.

Look for good sources of animal-based proteins like chicken meal and salmon meal on the ingredient label, as these are some of the most digestible proteins for cats. Avoid anything mentioned as “by-products” or “animal digest,” as these are not ideal sources of protein because they can vary widely in quality ranging from palatable to poor-quality ingredients.

Look never look beyond the second ingredient list when selecting your next bag of kibble – choose wisely! Finally, remember that moisture is key when selecting any food (especially kibble), so avoid dry foods that contain more than 10% carbohydrates; foods higher in carbs tend to produce smelly stools due to indigestible fillers (like grains and corn).

Follow these simple steps whenever you shop for your cat’s food: Choose a high-protein recipe that contains natural ingredients with no by-products or animal digests mentioned on the label — one with more than 30% protein is best! To reduce odor and encourage firmer stool output, check never go beyond the second ingredient list listed on the label – look only at sources of digestible animal proteins like chicken meal or salmon meal! Select a recipe featuring fewer than 10% carbs to ensure adequate moisture levels in our cats’ diets at meal times!

American Journey Grain-Free Dry Cat Food is an ideal substitute for other natural grain-free cat foods in the marketplace. That protein quantity is at approximately 40, and it very closely mirrors human diets because the protein mostly comes from meat and eggs. Duck and chicken you can find as the first five ingredients, and then eggs are the next ingredient – a high-quality choice to be included in the formula.

This food doesn’t contain pea protein; it’s not as high up on the list and surrounded by meat as it is. Therefore, little to no protein is contained in a veggie source. This food is entirely grain-free, as it is free from corn, wheat, and soy. It means it is better for cats’ stomachs and may eliminate some of the mess from their litter box.

This food was made here in the United States using ingredients from all over the world, and many essential amino acids were added in case your cat needs them. These additions also help reduce the number of peas used in manufacturing.


  • Made with real chicken as the first ingredient. 
  • It contains natural fiber from peas and dried beet pulp for healthy digestion. 
  • Includes antioxidants, vitamins, and minerals for a complete and balanced meal. 
  • No corn, wheat, or soy ingredients that can cause food allergies in cats. 
  • No artificial flavors, colors, or preservatives. 


  • Contains poultry by-product meal, which could be a low-quality protein and nutrition source. 
  • High carbohydrate content can contribute to weight gain.
  • Potentially contains gluten from wheat flour used as a binding agent in the kibble shape formation process.  
  • Some lower-quality grains, such as rice hulls.

Considerations When Choosing Food

When choosing cat food, there are certain things to keep in mind in order to ensure your cat has optimal health and nutrition. One of the most important considerations is ensuring the diet is complete and balanced. Many pet food companies will label their product as such. However, it’s still good to research and know what essential vitamins, minerals, amino acids, etc., are needed for optimal feline health.

It can also be helpful to read reviews of individual products by other consumers who may have had good experiences or bad experiences with the product. Additionally, you should consider if your cat has any specific dietary needs or allergies; this should influence the types of products you choose.

For cats that have chronic smelly poop, it can often be helpful to transition them onto a limited-ingredient diet that eliminates certain proteins and grains that may be causing the issue. Lastly, the smell is also an indicator of quality; when purchasing wet cat food, look for consistent texture and minimal smell for a high-quality mealtime experience for your pet!

Benefits of Quality Cat Food

High-quality cat food is specially formulated to meet the nutritional needs of cats, making it a smart choice for pet owners and a critical factor in promoting optimum health. The most nutritious and highest-quality cat food is made with quality, natural ingredients, and no artificial additives. In addition to providing balanced nutrition for cats, quality commercial cat food may also provide additional benefits such as:

Balanced macronutrients: Quality cat foods contain essential fatty acids, proteins, carbohydrates, and fiber that are important for optimal growth and development. Proper nutrition helps keep cats strong and healthy.

Improved digestion: Quality cat foods can help support healthy digestion by providing prebiotic fiber to feed beneficial bacteria in the gut. This helps promote nutrient absorption, balanced intestinal microflora, and regular bowel movements. Some quality diets also have specific added ingredients designed to reduce odors associated with smelly stools.

Greater immunity: Quality diets contain antioxidants such as vitamin E that help promote defense against infections or illness due to their antioxidant properties, which may help maximize your pet’s immune defenses against disease. Additionally, quality diets contain omega fatty acids shown to support joint health as well as skin health for cats of all ages.

Sustained energy levels: Quality cat foods provide cats with sustained energy throughout the day due to their lower carbohydrate content compared with some lower-quality alternatives that may cause fluctuations in energy levels throughout the day.

Home-made Alternatives

Home-made cat food can be a healthy and economical alternative to store-bought products. However, cats are obligate carnivores, meaning meat should make up most of their diet. In addition to being highly palatable, moist diets are often more digestible and may offer certain health benefits. Before preparing home-made diets for your cat, check with your veterinarian or a board-certified veterinary nutritionist to ensure the diet will provide all the essential nutrients your pet needs.

When planning home-made meals for cats, ingredients such as cooked meats (e.g., beef, chicken), poultry liver, fish, boiled eggs, and cottage cheese can be used in combination with canned or dry commercial food items that are formulated for cats. Be sure to avoid feeding raw meats, as this may pose a potential food safety risk due to bacterial contamination of uncooked foods. Additionally, feed only fish that have been specifically produced for human consumption and do not feed raw salmon or trout as these species contain parasites that could cause illness in cats.

Finally, there are many alternatives for adding fiber or carbohydrates to cat diets in the form of vegetables (e.g., broccoli and squash) or fruits (e.g., bananas). Be aware that some cats may not consume vegetables willingly, and avoiding them if they cause changes in eating habits may be best in some cases. Always cook all vegetables before serving them, and avoid adding onion or garlic, which can be toxic when fed in large quantities.

Tips to Reduce Smelliness

Tips to Reduce Smelliness

The odor of cat poop can be quite strong and unpleasant. In addition to cleaning your cat’s litter box frequently, you can also take steps to reduce the smelliness of your cat’s poop. Here are some tips to help keep unpleasant odors from becoming a problem in your home:

1. Feed your high-quality cat food with quality ingredients. Quality pet food will help ensure that all the necessary nutrients for a healthy diet are included in each meal, which can help reduce smelliness in the poop.

2. Feed your cat two or three small meals throughout the day. Eating smaller meals helps cats digest their food more efficiently, resulting in fewer smelly stools. It also helps to prevent overeating and potential weight gain.

3. Offer plenty of fresh water at all times so that your cat can flush out toxins through increased urination and hydration; this should also help reduce odors.

4. Include fiber-rich foods as part of your cat’s diet; fiber makes the waste move more quickly through the digestive tract, reducing its time in contact with bacteria that causes odor problems.

5. Try adding probiotics to your cat’s diet; these beneficial bacteria can help improve digestion, leading to fewer smelly stools over time.

6. Clean up after each event you think may have caused a smelly stool: spills, accidents, changes in indoor temperatures, etc. This helps eliminate lingering smells before they become too strong for even air fresheners and deodorizers to handle!

How do you know if cat poop is unhealthy?

Unhealthy or abnormal cat poop can vary in odor, texture, consistency, and color. When it comes to assessing the health of your cat’s fecal matter, you should keep an eye out for any abnormalities.

Strong odors often indicate something is wrong with your cat’s digestive system. Pay attention to how your cat’s stool smells and immediately notify your veterinarian if the odor changes drastically or if you detect a different smell than usual. In addition, please pay attention to the texture and consistency of their feces.

While some natural variations may depend on their diet, anything drastically different from their regular products may indicate that something needs to be corrected in their digestive system. Check the color of your cat’s poop routinely as well; normal stool can range from light brown to tan. If it has turned black, red, or greenish yellow, bring them to the vet for testing.

Also, keep an eye out for any undigested pieces of food, such as hairballs, in cats who groom themselves frequently; this could also be an indication of worm infestations or other internal disorders. Lastly, the frequency at which your cat defecates is important; they should have regular bowel movements each day with few interruptions, and no diarrhea is generally noticed until health issues arise in cats that already exhibit signs of low energy levels and vomiting due to poor appetite or unintentional weight loss due to increased activity levels as well as decreased food intake.

Buyer’s Guide: Selecting the Best Cat Food for Smelly Poop

When looking for the best cat food for smelly poop, there are some important factors to consider. The first step is to determine the source of your cat’s problem. If it is an infection from bacteria or parasites, then the solution will be different than if it is caused by improper nutrition. Once you have identified the cause, you can move on to selecting the best food for your feline friend to help reduce his smelly stool.

When shopping for cat food, first look at its ingredient list and make sure it includes a variety of proteins and healthy sources of carbohydrates such as brown rice or oatmeal. Avoid any brands that contain artificial colors or preservatives, and try to find one with added probiotics that support both digestion and immunity.

Next, look at the AAFCO (Association of American Feed Control Officials) labeling and make sure that it states that the food contains all essential vitamins and minerals needed for cats in all life stages – from kittens to seniors – so you are always feeding a nutritionally balanced diet.

Finally, be sure to consider your cat’s individual dietary needs when selecting a food brand. Suppose he has chronic loose stools or vomiting. In that case, he may need more easily digestible food like those with reduced fat or low-allergen recipes like grain-free formulas suited specifically for sensitive stomachs and digestive systems.

Additionally, specialty diets that include high levels of dietary fibers can help absorb excess moisture in stool and firm up loose stools caused by inflammation in some cats suffering from inflammatory bowel disease (IBS). Taking these key points into consideration will help ensure that you choose the most suitable cat food for reducing smelly poop in your furry friend!


In conclusion, there are many factors to consider when choosing the best cat food for smelly poop. By looking at your cat’s nutritional needs, understanding their individual preferences, and researching the ingredients of cat food brands, you will find food that helps reduce smelly poop and keeps your precious feline happy and healthy. It is also important to check the cat food labels for added sugars or artificial sweeteners, as these could contribute to smelly bowel movements. By carefully assessing your cat’s nutritional needs and providing only the best quality cat food, you can ensure that your beloved pet has everything they need to stay healthy and odor-free.
