Cleaning up after your pet comes with the territory of having animals in the house, but if you’ve ever had a cat before then you’ll know just how terrible the smell of cat poop can be.

They might be well-trained enough to use their litter box instead of going wherever they choose, but where are these litter trays kept?

That’s right – inside the house. This means the delightful stench of your cat’s latest defecation is bound to waft through your home and let me tell you, it’s nothing like the smell of freshly baked goods.

Even if you keep your litter tray in an area of the house that’s less frequently in use, it can still be unpleasant if you catch a whiff as you walk by, or for the unlucky person who ends up having to change the litter tray.

But have no fear! Diet is often the culprit behind particularly foul-smelling cat poop, and these days there are multiple brands that make food specifically tailored to improving the smell when it comes back out of the other end.

To help you find the best cat food to control fecal odor, we’ve scoured the internet and found 5 of the best available options currently available for you to consider.

Our buyer’s guide contains more information on what you should look out for, to help you make an informed choice.

Buyer’s Guide

At the end of the day, poop is poop. It’s never going to smell of roses, but if you notice a change in odor or it begins to get worse, it could be an indication of a bacterial infection or other health problems, so it’s worth consulting your veterinarian if you’re concerned.

However, something as simple as a change in diet could seriously improve your cat’s fecal odor in as little as 12 weeks.

Whilst there are some basic nutritional requirements that all cats need, they’re just like humans in that they have their own unique digestive systems, and stinky stool is more often than not the result of sensitive stomach issues.

With so many brands advertising as the best option for your furry family member, it can be difficult to figure out which type of cat food is going to provide them with the best nutritional benefits whilst also minimizing the odor their feces emits, which is where our handy buyer’s guide comes in.

Read on to find out which factors you should consider when deciding what’s for dinner for your cat.


All cats require a balanced diet, which should include proteins, fats, vitamins, and minerals.

Good digestion results in more regular bowel movements, so it’s a hugely important factor to consider when trying to find a new cat food that will improve the smell of your cat’s feces.

One of the best things about cat food that is specifically designed to help with controlling fecal odor is that they tend to include ingredients that are gentler on the stomach, making it easier for your cat to digest them.

As a general rule, the first ingredient listed should be some type of animal protein, as this is essential for your cat’s overall health.

Always check to see what else your cat food contains, and avoid brands with a list of ingredients as long as your arm that include unpronounceable names or numbers.

It’s always important to know what you’re putting into your cat’s body, as that’s what will be coming out the other end.

Even more importantly, knowing what ingredients are used in their food will help you ensure there’s nothing that’s going to pose a risk to your cat’s health.


Even if you think the food you’re giving to your cat is premium-quality, that doesn’t necessarily mean it’s packed full of the right nutrients.

Cats are just as prone to allergies or sensitivities to certain foods as humans are, so the most extensive research into the ingredients of your cat’s food can’t guarantee that it won’t disagree with your cat.

You might be surprised to find out that gluten allergies are rarer in cats than adverts for their food would have you believe, whereas chicken, dairy, beef, and egg are among some of the most common allergens.

The best way to figure out if it’s a particular ingredient that’s worsening the smell of your cat’s feces is to try out a diet with limited ingredients to isolate the problem. This should allow you to more easily detect a trigger or irritant that’s affecting your cat’s stool.

Once you’ve successfully isolated and determined the cause of your cat’s allergies, it’ll be much easier to avoid foods containing this (or these, as you may find there’s more than one thing your cat’s reacting to) which will hopefully improve your cat’s fecal odor.

Flavors and Preferences

When choosing the best cat food to help with the smell of their poop, it’s important to keep in mind that your cat will have to actually like what you’re putting in front of them.

Just like a fussy toddler, if they don’t like it, they won’t eat it, which will render all the nutritional benefits of the cat food you’ve chosen pointless.

Luckily, there are so many different brands and types of cat food that with some trial and error, you’re bound to find a cat food that’s both tasty and beneficial.

The two main categories of cat food are wet and dry, and some brands offer options for both so you can alternate or feed your cat a mixture of the two, depending on their preferences.


Just because you’ve seen a type of cat food advertised on your television, it doesn’t mean it’s the best choice for your cat.

With that being said, some trusted brands are well known for making high-quality food that you can’t go far wrong with choosing.

There’s definitely no harm in sticking to a favorite brand if your cat seems to enjoy their food, and as long as they’re providing the necessary nutrients and health benefits then it’s a win-win situation for you and your cat.

Frequently Asked Questions

Why do cats cover their poop?

Although cats are generally known to be particular about cleanliness, the reason cats bury their poop is believed to be a natural feline instinct.

Before they became domesticated animals, cats would use the scent of their feces to mark their territory, and burying it is a sign of submission so as not to challenge a more dominant cat.

What can cause diarrhea in cats?

Diarrhea can be caused by a number of factors, ranging from minor to serious.

Some common causes include a change in diet – which can be mitigated by slowly introducing the new cat food and phasing out their previous food – inflamed bowels, worms or parasites, pancreatic disease, or even cancer.

Visit your vet if you’re ever concerned.

Why does my cat choose to not poop in their litter box?

There are a few different reasons why your cat could be choosing to poop outside of their litter box.

It could be a case of your cat believing they have dominance over you, which they’re asserting by pooping wherever they please.

However, it could also be a sign of illness or health issues, such as a UTI (urinary tract infection) or digestive problems, so if you’ve noticed a change in your cat’s behavior it’s worth consulting your vet for advice.
