Best Cat Food For Smelly Poop: Our Top 12 Choices for 2021

There are a number of reasons why your cat’s poop smells awful, but often this is down to what a cat eats.

After studying the connection between cat food and waste, we feel confident we can help you find the best cat food for smelly poop.

As cat owners, we know that a cat poop’s smell can be one of the most horrid things out there. There was a time when I wanted to mask up every time I cleaned the litter box.

Fortunately, that’s over for me now. If you’re going through the same thing I did back then, you may be wanting to find a solution fast. 

Read on for an in-depth discussion about how to deal with felines and their unpleasant fecal odor.

Why Does Cat Poop Smell?

Stools are, of course, not fragrant at the best of times, but sometimes they can be downright strong and putrid.

The cause for foul smelling cat poop can be down to a number of factors, and it’s important to know which one is giving your cat and you a problem so you can find the correct remedy. Let’s talk about each one.

1. Your cat’s diet is low-quality. 

Those cheap and colorful cat food products that are so tasty for your cat? Those usually contain a lot of fillers and artificial flavors or ingredients that result in foul-smelling feces.

While your feline may love them a lot, the poor quality ingredients in those commercial cat foods may also be the reason why his stinky poop smells as it does. 

Another thing, your cat may have food allergies and he may be reacting to an ingredient or ingredients in the food he is being fed. If cats eat something that disagrees with them, it can lead to the problem you are facing now. 

2. There are bacteria in his colon.

Eating cat food that has been contaminated with bacteria like salmonella or E.coli can lead to smelly stools, often accompanied by inflammation, diarrhea, and indigestion.

It doesn’t just stop with cat food. Your cat can also get the bacteria from eating the birds or rodents he catches.

3. He’s got a parasite.

Intestinal parasites can cause excessive gas, smelly poop, and diarrhea in your cat. Coccidia, Trichomonas, and Giardia infestations, all of which can cause a cat’s poop to turn odorous, can infect a cat in a number of ways.

• Coccidia can infect your kitty if he eats a contaminated rodent.
• Trichomonas usually infect cats under the age of one year. It can be transmitted from cat to cat via shared litter boxes.
• Giardia is usually transmitted by eating or sniffing the cysts from contaminated water or ground, or directly from a contaminated host.

4. Your cat has digestive disorders.

A cat’s digestion can be a delicate thing. Some felines suffer from digestive disorders which can cause poop to become putrid.

They may lack digestive enzymes, have an overgrowth of flora and fauna in their digestive systems, or suffer from an inflammation of the bowel wall. These are all signs of malabsorption, and the reason why your pet may have bowel odor issues.

5. He’s on medication.

If your cat is ill and on medication, those meds may be the culprit for the smelly poop. Those vitamin and mineral supplements can also result in smelly stools. 

Most cat foods these days are balanced and complete, so there’s really no need to add supplements to your cat’s diet unless your vet advises you to. 

6. You’re buying the wrong kind of litter.

The wrong kind of litter can not quite hide or disguise the scent of smelly poop. Try and experiment with different kinds of litter to see which works best with your cat.

Be careful in your selection. Some cats are particular about their litter and may poop outside the litter box if they’re unhappy. Older cats need a litter that’s soft on their paws, while other cats are turned off by strong scents.

Selecting The Best Cat Food For Smelly Poop

You know that old adage, “cleanliness is next to godliness”? You may have found out to your dismay that the saying doesn’t work all the time, especially not when dealing with smelly cat poop. 

Now while regularly cleaning the litter box may help some, it doesn’t really get to the bottom of the problem — why your cat’s poop smells really bad.

If your veterinarian has ruled out any medical issues, then it most probably is your cat’s diet that’s causing the problem. So how do you go about switching to the best cat food for smelly poop for your feline?

1. Look at the label.

Does it have artificial flavors or does it rely on natural flavor to make it appealing to cats?

Most meaty dishes don’t need to add artificial ingredients to entice kitties to eat, while those that use lots of fillers or cheap ingredients will usually resort to artificial stuff. And those artificial ingredients are one of the main causes of that icky cat’s poop smell. 

Make sure when you select a cat food that starts off with a meat ingredient and that there’s plenty of high quality animal protein in the recipe.

Plant protein is okay, but cats are obligate carnivores. They won’t thrive on a diet filled with mostly starches or produce. So try to stay away from formulations that use plant protein as their main protein source.

Lastly, try to steer away from byproduct meals or unnamed meat meals. These are not high quality cat food ingredients at all.

You can’t say precisely what part of the animal is being used with byproduct meals. With meat meals, you can’t tell exactly what animal was used. 

2. Check for food allergies.

Is your cat sensitive to an ingredient? A cat’s digestion and body can go all crazy because of allergies or food sensitivities.

Some cats might show only mild symptoms, like smelly poop or slight itching on a cat’s body, while other cats may have more severe reactions. 

Make sure that your cat is not allergic to any ingredient in the food. Usual culprits for food allergies are gluten, grains, or specific animal proteins.

Pea protein allergy is not unheard of too. And since it’s mostly a carb filler, your cat can do without pea protein in his diet.

Limited ingredient cat food is often given to cats with food sensitivities because of its use of a single high quality animal protein and few ingredients (less risk). 

3. The type of cat food you feed matters.

Many cat owners insist that the best cat food for smelly poop is a raw cat food diet. If you go to forums where pet owners discuss smelly poop problems, raw cat food is almost always recommended. This doesn’t mean that dry food or canned cat foods won’t help. It only means that digestibility is the key. 

Raw usually contains a lot of animal meat and little of anything else, so it completely answers a lot of a carnivore’s nutritional needs without creating plenty of waste. 

If preparing and giving a raw food diet doesn’t work for you (because it can be inconvenient and messy), you can opt for freeze dried cat food instead.

Freeze drying is a process that happens when you rapidly freeze food. It does not involve cooking the food nor including preservatives. The process itself is the preservative. 

Dry or canned cat food is also just as good. Just choose a recipe that is packed with animal protein. If it does include grains, legumes, or potatoes, these should only be supporting ingredients and should not make up a huge part of the food.

4. Lactose in cat food isn’t tolerated well by many cats.

It isn’t just humans that are lactose-intolerant. Most cats don’t tolerate dairy too. If your cat’s food or treats contain cow’s milk, it might give your cat flatulence, digestive distress, or the dreaded smelly poop.

5. Pick foods with premium animal-based fats.

Some recipes use plant-based oils to provide your feline with the energy he needs.

While that’s not bad nor harmful — in fact, some are quite healthy —it’s always best for your cat that he gets most of his fat requirements from animal sources as those are more biologically appropriate.

Salmon oil and chicken fat are good examples. Plant-based fats can provide supplementary fat support instead.

6. Go for one with enough fiber.

The right cat food for smelly poop should have a good amount of fiber. Fiber helps turn a cat’s feces more solid, so cat poop can be easily pushed out.

If your cat is frequently going to the toilet, which causes the smelly poop to happen in the first place, the fiber will firm up that waste in no time and reduce that nasty feces odor. 

Grains are packed with fiber. You can also look for potatoes or legumes if your pet is sensitive to grains. Just make sure these don’t make up a huge chunk of the diet.

And steer away from cheap fillers like brewers rice or corn gluten meal. Whole grains are better. 

7. Wet cat food, dry, raw, or freeze-dried?

While checking for healthy ingredients is a must, take note of what your cat likes too. If your cat prefers wet food over dry food, that should also make a significant impact on your selection. All that checking for healthy stuff won’t matter if your cat won’t eat his food. 

8. Lastly, the brand shouldn’t matter.

There are some small cat food companies that provide just as excellent-quality food as known commercial cat food brands. What really matters is reputation and the ingredients in the label.

Some big-name brands are quite popular with consumers and have such great reviews, but if you check the content of their cat foods, you probably would not be happy feeding your cat with those.

Before you get swayed by popularity and ratings, take a peek at the ingredients. If everything looks fine to you, research the brand if it has had recalls and when was the last one.

Don’t go for one with a recent recall history. The best cat food for your pet is the one that’s the healthiest.

What Else Can You Do About Smelly Poop?

There are many ways to reduce odors aside from buying cat food for smelly poop. Here are some tried-and-tested steps you can take so you don’t have to put a hazard suit on every time your pet goes to the toilet:

1. Scoop daily. 

Control litter box odor by cleaning your cat’s bathroom at least once a day. This is to prevent odors from a cat’s feces from lingering and to keep your and your cat’s noses happy. If you’re upset about using a dirty toilet, don’t you think your cat will be too?

2. Wash your cat’s litter box every month.

Scooping every day and replacing it with new litter won’t really keep your cat box clean. There will still be traces of your cat’s litter box habits remaining in the old litter resulting in that unpleasant litter box odor.

What you need to do to keep the smell down is to wash the cat litter box thoroughly each month. Throw out all the litter and scrub and soap the box rigorously.

Try not to use bleach even if that would completely disinfect your cat’s litter box. Bleach is quite strongly scented and may result in your cat avoiding his litter box when he needs to go.

After washing, dry then put in fresh litter. 

3. Replace your pet’s litter box. 

Sometimes, that unpleasant litter box odor you’re scenting is not from smelly poop that’s been dropped recently.

Litter boxes can allow bacteria buildup through those tiny scratches your cat has been making on the litter box when he tries to bury his waste.

If your pet has been using that litter box for a long time, it may be time to replace it with a new one.

A few tips in choosing the right cat litter box: 

• It should at least be as long as your cat. Measure from his nose to the tip of his extended tail. 
• It should be low enough that your cat, and this is particularly important for older cats, can easily climb over.

4. Your cat’s litter box should be well-ventilated.

It’s normal to want to hide unpleasant things from sight (and a cat’s feces is definitely one of those!), but keeping your pet’s litter box tucked away in a confined and small space can lead to litter box odors concentrating in that spot.

Your cat probably won’t thank you every time he needs to step into that place to do his business. And you won’t be happy smelling that cat’s poop stink that just won’t go away.

Place the litter box in a ventilated spot instead to keep that litter box odor down and stop it from staying in place. 

5. Baking soda works wonders.

If you’re still having smelly poop or litter box odor problems, sprinkle a little baking soda on the litter or open a box of baking soda and keep it near the litter.

That should control feces odor. And since baking soda is made to absorb odors but has no scent itself, your cat’s sensitive nose won’t be irritated. 

Final Thoughts

Sometimes, it really is as simple as changing your cat’s food to get rid of the root of the problem. Quality cat food can do so much for your pet aside from getting rid of stinky poop.

You’ll find that with a proper diet and the right cat food for smelly poop, your cat will look more fit, be more active, and generally be healthier overall.

Does wet cat food cause smelly poop?

Wet cat foods provide more moisture, which can make bowel movements easier for your cat. They also tend to contain less fillers, which mean that there are more digestible ingredients. Often times, what's causing the odor in the litter box is the bacteria working to digest the parts of the food that your cat could not.

What causes foul smelling cat poop?

The cause for foul smelling stools in cats or humans can be very similar. It can be the food eaten, the bacteria in the colon, and on occasion serious health problems. Additionally diarrhea and the presence of excess gas can cause bad odors. Many feline disorders are accompanied by diarrhea and foul smelling stools.

What foods help poop smell better?

Sulphur-rich foods include: Coconut milk, juice, and oil. Certain vegetables, including broccoli, cabbage, cauliflower, horseradish, kale, radish, and turnips. Dairy products (except butter).

How do you deodorize a cat box?

Just sprinkle a thin layer of baking soda over the bottom of the box, then pour the litter on top of it. If you don't want to use straight baking soda, Arm & Hammer makes a baking soda cat litter deodorizer that works well.
