Alternative Cat Food for Smelly Poop

What Are the Qualities of The Best Cat Food for Smelly Poop?

The best cat food for smelly poop is usually a food capable of addressing any dietary problems your feline friend might have. While there are various factors that can contribute to your cat’s bathroom habits, the wrong diet is the most common cause of terrible smells. 

Good cat food for smelly stool should include:

Free from allergenic or irritating ingredients

Limited ingredient cat foods are often a common solution for cats with smelly poop. This is because most of the digestion problems caused by cat foods are a result of something within the food reacting badly with your cat’s digestive system. If your cat food is packed full of extra ingredients and additives, it’s more likely to cause irritation. 

Avoid any common allergens, including grain, and make sure you stay away from cat foods that contain any lactose. Remember, your cat will likely be lactose intolerant, so the presence of any lactose in their diet will only make their bathroom habits worse.

High-quality food sources

Higher quality sources of food are also less likely to cause problems with your cat’s digestive system. Any food you buy for your cat should have a good source of protein as the number one ingredient. This protein should ideally be from an organic source, like cage-free chicken. 

While it’s important to consider your cat’s preferences, focus on foods that are packed with protein and contain a few extra vitamins, minerals, and antioxidants. Probiotics, prebiotics, and substances which help to promote natural digestion can be useful here too.

Consider raw food

If your cat generally has a lot of digestion issues, you might consider turning to raw food. Though more expensive, and a little more complex to prepare than the standard cat food, raw food is free from anything which might cause irritation to your cat’s digestive system.

You can even make your own raw food at home and carefully choose each ingredient yourself.

Raw food gives your cat a diet closer to what they would be likely to have in the natural world. Before you switch to a raw food diet, however, you may want to look at speaking to your veterinarian and getting their advice. They may be able to offer insights to help you make the best possible food for your cat.

Qualities Of The Best Cat Food For Smelly Poop

Things to Look for In Your Chosen Cat Food

The best cat food for smelly poop will be focused on aiding your cat’s digestion while minimizing anything which might irritate your feline friend’s sensitive stomach. If your cat has a specific issue with their health that might be contributing to their bathroom issues, consider asking your vet for advice on which food to use. 

It’s also worth making sure the food you choose can still support your cat’s unique health requirements if they have any. Some factors to look for include:

  • Increased moisture: While there are dry foods on the market which can help with digestion problems and smelly bathroom habits, wet food can offer a lot of added benefits. The increased moisture will help to move food through your cat’s digestive system, particularly if they don’t drink a lot of water on their own. If you’re not using wet food for your cat’s diet, make sure they have access to plenty of fresh drinking water.
  • Good fibers: While the fiber content shouldn’t be too high in a cat’s food, there should be enough beneficial fiber in the meal to ensure your cat can digest food correctly. A little added fiber could be all it takes to solve a number of problems with your cat’s stomach. When your cat’s digestion works better, their poop doesn’t smell so bad.
  • Easy to digest carbs: Carbs are an important part of your cat’s diet, as they ensure your feline friend has all of the energy they need. Looking for easy-to-digest carbs and avoiding any foods with high amounts of grain will help your cat to process their food more effectively. Once again, easier digestion means fewer bathroom troubles for your cat.
  • Good protein source: Remember, cats are obligate carnivores, so the most important number one ingredient you can have in any cat food is meat. A significant portion of your cat’s diet needs to come from high animal protein to keep them healthy. Avoid any cat food with low protein levels, as this won’t give your cat the nutrition they need.
  • Limited ingredients: Cats don’t need a huge variety of different natural ingredients in their food to stay healthy. The more limited the ingredients in your cat food, the better off your cat might be. More ingredients mean more chances your kitty will be exposed to something which irritates its stomach or digestive system.
  • Healthy fats: While too much fat can be problematic for your cat, they’ll still need access to a decent amount of high-quality ingredients and fat in their diet. A higher fat content will help to ensure your cat gets the right amount of nutrition from each meal. Less fat means your cat is more likely to overeat, which can lead to problems with digestion. Look for fat from animal sources like chicken fat and salmon oil (omega-fatty acids).

Things to Avoid

It’s worth remembering every cat is different, and the dietary requirements and digestive health of your feline friend might differ compared to those of other cats. Paying attention to your kitty’s unique health needs and food preferences will help you to make the right choice. 

Based on what you know about your cat, it’s worth taking extra steps to avoid substances that might be problematic for them. For instance, food sensitivity triggers commonly contribute to digestion problems and smellier litter boxes. One of the biggest triggers for cats is also common proteins like chicken, seafood, and beef. If you know your cat has an issue with one of these foods, it might be worth experimenting with different proteins. 

Another common source of irritants for cats is grain, which is why so many of the top foods on the market are entirely grain-free. Avoid anything with soy, corn, or wheat as a large ingredient. Similarly, it’s also a good idea to avoid artificial ingredients as much as possible. Artificial flavors, preservatives, and colors can often irritate your cat’s stomach. 

Don’t forget to stay away from dairy and milk products too. Most cats are lactose intolerant, and foods or treats with milk as an ingredient can lead to worse stomach problems. 

If you’re not sure what kind of foods, recipes, or ingredients might be problematic for your cat, the best option is to try a limited ingredient diet. This can help you to avoid many of the most problematic ingredients in cat foods.

Best Cat Food for Smelly Poop: The Verdict

The best cat food for smelly poop might take a while and a little experimentation to find. You’ll need to choose a food that supports your cat’s digestion, but also appeals to their individual preferences, which isn’t always simple. 

Always keep an open mind to parasites, bacteria, and bacterial infections (salmonella) as these can cause stinky poop and diarrhea.

Our favorite option is the Natural Balance Limited Ingredient diet cat food. Not only does this limited ingredient food reduce the risk of your cat suffering from allergic responses to various irritating foods, but it’s packed full of high-quality nutrition. With this simple dry cat food, you can cut out common problematic foods, and still give your kitty the right balance of protein, antioxidants, minerals, and vitamins to keep them healthy.

Good luck finding the food best for tackling your cat’s smelly litter box habits.
