Things To Know Before You Buy…

If you’re confused about which cat food to go, here are some great tips to help you find the best cat food for smelly poop.

Things to Look Out For When Choosing Cat Food

Your cat’s poop is always going to smell, but if it’s particularly strong, this may indicate that your cat’s food may be hard to digest, or the ingredients may not be suitable for its digestive system.

Check out these factors before buying your cat’s food.

Animal ingredients

Cats are carnivores in nature, and as a result, they’ll be able to digest animal products more than plant products. A diet filled with plant products may cause smelly poop.

Remember that these carnivores creatures require their daily dose of high-quality meat.


Food allergy is one of the most common reasons for smelly poop. To reduce this, choose cat food that’s not filled with overwhelming ingredients or one that has a novel source of protein.

Pay special attention to your cat’s diet, every cat is allergic to different ingredients.

Just because a diet worked for one cat doesn’t mean it’ll work for yours. Just like humans, every cat is unique so make sure you observe your cat’s reaction to any new food.

No Fillers or Additives

Always look for products that have zero additives or fillers. Cheap and substandard fillers like wheat and corn are known to cause smelly poop habitually. Thickening and artificial additives like guar gum and agar-agar can also lead to bad odor.

A high-quality premium cat food should be devoid of these ingredients.


If your cat is having difficulty digesting its food, then smelly poop will probably be an issue. To increase digestibility, look for cat foods that contain protein from animal sources and low-level carbohydrate fats.

Steering clear of these ingredients should help you regulate smelly odor and promote your cat’s health. Almost every premium brand caters pet products that are devoid of these ingredients and contain high-quality, healthy ingredients. You shouldn’t have trouble finding one for your cat.


1. Which ingredients are important to reduce smelly poop?

Look for a cat food high on animal-based ingredients and fat with fewer carbohydrates.

Also, avoid fillers, soy, grain, wheat or anything artificial. Not only can they aggravate smelly poop but they can also be irritable substances for most cats.

2. Should I give wet or dry food?

They both have their pros and cons. Dry food is better economically and will prevent dental tartar, but a wet diet holds more water and will be more suitable for cats that have urinary troubles.

Wet diets also provide more moisture and hydration for healthier digestion.

3. How do I switch cat foods?

Changing your cat’s diet may require some adaptation. Initially introduce small amounts of the new food with their current diet and continuously keep increasing the amount.

By seven days, your cat should adjust to the new food.

4. Do cats need meat?

Absolutely! Cats can’t survive on a vegetarian diet. They’re carnivores creatures, and they require meat by nature. Keeping them on a vegetarian will lead to health complications.

5. How frequently should I feed my cat?

There’s no single answer for this. It all depends on your cat’s health, requirements, and activity level. Generally, two to four times a day should be sufficient.

6. Can I feed my kittens adult food?

Generally, adult cat food is much harder to chew and more dense as compared to kitten food. It’s better to look for cat food specifically aimed at kittens. It’s much easier to eat and digest for them.

Kitten food also contains ingredients that are specially targeted towards a healthier body development.
