Best Cat Food For Less Smelly Poop Buying Guide

Cat poop stinks. We’ve established that, and we’re never going to be able to completely remove that odor, but a change in diet can make it less offensive.

There are a huge amount of brands on the market that have a special range to help digestion, and that can make it difficult to identify the one that’s right for you.

That’s why we have put together this helpful buyers guide full of all the information you need to find the perfect cat food for your pet. 


The most common reason for smelly cat poop is the food that your cat is eating, which isn’t really surprising considering some cat food already smells pretty bad before your cat has eaten it.

Cat food is packed full of so many different ingredients and nutrients to keep your pet in good health, however, it could be an allergy to an ingredient that is causing the strong odor.

Through trial and error, you will probably be able to identify certain ingredients that your cat might have an adverse reaction to, for example, certain meats might not agree with your cat’s stomach, and you will know to avoid flavors like this in the future. 


Just like human beings, cats are individuals, and just like human beings, cats can be extremely fussy. It is likely that your cat will have certain preferences towards wet or dry food, towards specific meat or fish flavors, and even towards specific brands of cat food.

Not all cats are fussy, some will eat whatever food is put down for them, but if your cat is particularly fussy you can normally tell which flavors or brands they prefer by the amount they eat and whether they prefer wet or dry food by giving them a combined mixture and seeing which they eat the most of. 

Wet Vs Dry Food

At a basic level, there are two options for cat food: wet or dry. Or, of course, a combination of both.

The best choice for your cat will partly come down to preference as if your cat does not like dried food or refuses to eat it it would be pointless feeding it to them. But it also comes down to which is better, and the answer is both.

It is very important that your cat has a balanced diet, especially if your cat suffers from a sensitive stomach. Giving your cat a mixture of wet and dry food, or rotating the food types will expose them to different types of proteins and will also reduce the likelihood of them developing further allergies. 

Common Allergies

There are some common allergies to watch out for if your cat has a sensitive stomach.

Despite what advertising suggests, a gluten allergy is very uncommon in cats and some of the most common allergens are chicken, dairy, beef, and egg.

This might come as a surprise as cats are often depicted drinking milk and chicken is one of the most popular flavors on the market, but if your cat smells particularly bad after eating a food containing any of these ingredients that could be the cause.
