Litter Boxes for a Cat with Diarrhea Top Picks

If you are pressed for time, here are the top 5 picks of cat litter boxes for cats with diarrhea, that I recommend for your kitty:

  1. Petmate Top Entry Litter Box

Factors to consider when buying a litter box for a cat with diarrhea

1.    The Size of the kitty pan:

The most important factor in choosing a litter box for a kitty with diarrhea is the size of the litter box.

Make sure that the box is large enough so that there is plenty of room for him to squat comfortably and that it is easy for him to climb into it and out again.

You want to avoid any sprays from the loose stool finding their way outside the box onto your carpet or floor.

If you have multiple cats, then it’s important to get a large enough box so that they all have enough space to move around in without bumping into each other or getting stuck behind each other.

2.    The height of the cat box:

Ensure that the litter tray is high enough to avoid any loose sprays from your cat with diarrhea landing outside the litter box.

3.    Ease of cleaning:

Another factor to consider when buying a new litter box is how easy it will be to clean up after your cat uses it.

Considering the loose nature of a feline’s stool, you want to ensure that you can reach every corner effectively while cleaning.

You want to avoid a box with crevices and hard-to-reach corners since the loose stool may find its way there and begin to stink.

4.    Good odor control:

The smell of cat diarrhea can be very strong and unpleasant.

If you’re looking for a solution to this problem, then consider buying a litter box that has a carbon filter.

Carbon filters do not absorb odors, but they trap them, which means that your cat will be able to use the litter box without smelling anything unpleasant.

In addition, these filters are easy to clean and maintain, so you won’t have to worry about getting rid of any odors when it’s time for cleaning.

Why is my indoor cat’s poop runny? Causes of feline diarrhea

Your cat may be having diarrhea outside of the litter box or in the kitty tray due to:

1.    Consuming the wrong food:

Ingesting the wrong type of food can cause diarrhea and even vomiting.

2.    Change in diet:

You don’t want to switch her food too quickly since you can end up with explosive diarrhea all over the home.

3.    Lactose intolerance:

Lactase (the enzyme that aids in lactose digestion) levels in kittens drop by about 90% after they are weaned.

Adult cats do not create enough lactase to digest the lactose found in milk correctly.

This explains why many adult cats vomit or have diarrhea after consuming too much cow’s milk.

Even a few teaspoons of milk might produce vomiting and diarrhea. Why should you take a chance?

4.    Chewing on houseplants:

If your cat has a natural need to consume plants and there isn’t any grass accessible, he or she may choose to devour one of your houseplants.

 Although eating houseplants is unlikely to be harmful, it can cause vomiting, diarrhea, excessive salivation, and lip irritation.

5.    Social stress and emotional moods:

Aggression to catalepsy is all signs of social stress.

 Failure to bury excrement, house-soiling, overeating, anorexia, diarrhea, and constipation, are some of the symptoms.

Within 2 or 3 days of short-term stress, fear, or tension, can cause no burial of feces, psychologic incontinence, vomiting, and diarrhea.

6.    Upper respiratory tract infections:

Cats suffering from upper respiratory infections may experience secondary diarrhea or cease using the litter box.

Secondary diarrhea is linked to mucus consumption, but it could also be linked to the emotional strains of illness, treatment, or hospitalization.

7.    Eating placentas after giving birth:

After delivery, a placenta for each kitten should be passed. Your cat will instinctively eat it numerous consumption of placentas might cause diarrhea.

8.    Heatstroke:

It causes your cat to grow weak, unsteady, and possibly have diarrhea if left untreated.

9.    Feline intestinal parasites:

Hookworm symptoms include diarrhea, constipation, weight loss, and weakness.

Toxoplasmosis can result in: fever, poor appetite, vomiting, weight loss, fatigue, and, diarrhea.

Coccidia is a highly contagious intestinal parasite that primarily affects kittens, but it can also affect adult cats. Symptoms include weight loss, dehydration, vomiting, and mucous-coated diarrhea. As the infection advances, diarrhea frequently contains blood.

Commonly yellow diarrhea is a symptom of giardiasis.

10. Food intolerance or allergy:

Some cats may develop an allergy or sensitivity to one or more pet food ingredients. Wheat gluten, corn, and other grains might potentially cause an allergic reaction.

An allergy’s symptoms aren’t always visible. Your kitty may vomit or have diarrhea.

Certain foods can make cats intolerant or cause them to acquire intolerance. It’s sometimes a particular protein source, like beef, fish, or chicken.

Food intolerances are most commonly associated with vomiting and/or diarrhea, although they can also manifest as dermatologic symptoms.

How can I firm up my cat’s stool?

When should you call a veterinarian?

If a cat’s diarrhea should be evaluated by a veterinarian if:

Can a dirty litter box cause diarrhea?

Yes, a dirty litter box can cause diarrhea.

Cats groom themselves using their tongue and they may end up licking their paws after leaving a dirty cat tray.

By ingesting the dirt that may contain microbes, the cat’s intestinal tract may be affected resulting in diarrhea.

While a dirty litter box is not the only cause of diarrhea, it does increase the risk.

One way to prevent diarrhea is to make sure that your cat’s litter box is clean and well-scented.

Cleaning out litter boxes daily with a scooping tool or scooper will help keep smells under control.

How do I get rid of cat diarrhea from the litter box?


If your cat has diarrhea, it is crucial to keep the litter box clean, or else the liquid stool may spread diseases through the carpet in your house.

While you and the rest of your family should always sanitize your hands after handling the feces, it’s also important to frequently replace the cat litter.

We recommend cleaning out all traces of feces and bacteria-infested liquids right away and changing out the entire litter box with a fresh supply of clean cat litter each day.

If you don’t take proper measures to ensure health and hygiene, it could lead to serious health issues for both humans and pets.

Regarding the litter box, I recommend a good high-sided box or the litter robot to keep things in and prevent any accidents outside the box.

Also, remember to wash the cat’s paws after each visit to the litter box.
