What are the Causes of Diarrhea in Cats?

Many factors can cause loose, watery stools in cats.

The clinical appearance of diarrhea in cats due to any of these causes are the same: frequent (more than 4-5 watery stools in 24 hours), soft, and watery stools.

Depending on the cause of diarrhea, a pet might even have dark or bloody stools, vomiting, gas in the form of belching, bloated stomach, and flatulence.

Like in humans, cats also have a gastrointestinal tract which has defense mechanism against irritants of many sorts – irritants that cause contents to move a greater number of times than usual.

Common ‘irritants’ that can cause your cat’s diarrhea include: worms, parasites, bacteria, viruses, spoiled foods, toxins in the environment, food sensitivities, indigestible foods like hair, cloth, or plastic, as well as bone fragments.

Your cat’s GI tract then tries to flush out these irritants by using rapid movements. However, because the stools are thrown out so quickly, the colon does not absorb much water from the stools as it normally does.

This results in stools that are abnormally liquid, loose, and watery.

Because there are so many varied factors that can cause diarrhea in cats; we have to be alert to the possibility of other conditions lurking behind these symptoms.

However, in most cases, chronic diarrhea and watery stools in cats arise from eating the wrong kind of food, indulging in spoiled food, overeating, parasites, and viral infections.

How to Treat Chronic Diarrhea in Cats

1) Avoid feeding for 24-36 hours

Let your cat fast for a day and a half. This will give the GI tract a chance to reset itself. Preventing food intake can also help your pet’s digestive system flush out the irritants causing the diarrhea and regulate itself.

2) Provide plenty of fluids

Please keep plenty of fresh drinking water available for your cats.

Constant chronic diarrhea and loose stools can cause dehydration which you must avoid at all costs.

You can also offer your pet some broth or stew made with vegetables, rice, and meat or bones. This will help prevent dehydration and also eliminate toxins and gastric irritants from the colon.

3) Change the food

Nutrition is extremely important in managing chronic diarrhea and your vet will recommend certain dietary changes along with other therapies.

Many vets recommend diets with novel protein, low fats, and high fiber.

These have helped many cats overcome chronic diarrhea.

Switching to diets that do not contain a source of allergy or food sensitivity can also help cats with sensitive stomachs.

In some cases, a new diet can worsen the condition. So, you have to do some trial and error until symptoms reduce.

4) De-worm your pet

Regular deworming can also prevent chronic diarrhea in cats.

De-worming prevents parasitic worms from laying eggs in the GI tract which tends to upset the balance and cause vomiting and diarrhea.

Speak to your vet about regular deworming of your pets.

5) Treat underlying infections

Certain bacterial and viral infections can also cause chronic diarrhea.

Thankfully, treating these issues can help overcome the symptoms almost instantly.

6) See your vet if symptoms persist

If diarrhea persists or is accompanied by other symptoms like vomiting, bloody stools, fever, and lethargy, please see your vet right away.

How does a High Fiber Cat Food for Diarrhea Help?

Fiber is extremely beneficial in the treatment of chronic large and small bowel diarrhea in cats.

There are two forms of fiber in cat foods: soluble and insoluble. Soluble fiber forms a gel in solution which slows down the GI transit time. This reduces the number of bowel movements in cats having chronic and persistent loose stools.

Soluble fiber also increases the probiotic or good bacteria in the gut.

These bacteria regulate the digestive system and increase fermentation in the gut to provide an additional source of nutrition for the colonocytes – cells of the colon.

Insoluble fiber does not form a gel and is fermented to a lesser degree than soluble fiber. But it adds bulk to the stool and improves and regulates bowel movements.

Fiber is necessary for maintaining your cat’s GI tract health.

It also assists with passage of difficult-to-digest items including hairballs. Fiber is also essential for weight management and in controlling glucose levels in cats.

In short: the best high fiber cat food for diarrhea has a soothing effect on your cat’s digestive health. It reduces inflammation and irritation, eases the passage of waste, and encourages proper elimination to keep the digestive tract clean.

Why are Pumpkin-based Cat Foods Good for Cat Diarrhea?

Pumpkin is an excellent source of fiber for cats.

As a natural fiber source, pumpkin regulates your cat’s intestines and keeps them in good working order. This means that, if your pet has diarrhea or constipation, pumpkin will help the stools get back to the right consistency

Moreover, most cats, and even the pickiest of them, are known to love the sweet taste of pumpkin and other squashes.

It further helps that pumpkins are an excellent source of beta carotene, B-complex, and vitamin A. All these enhance immunity, vision, and benefit your cat’s overall health and well-being.

How to Select High Fiber Cat Food for Diarrhea?

Here are some factors to consider when selecting food with fiber for cats with diarrhea:

A) Contains easily digestible fiber

High-quality, easy to digest fiber for cats with diarrhea includes pumpkin, psyllium husk, peas, fruits, and vegetables. These fibers help regulate and cleanse the GI tract to prevent loose and watery stools.

B) Contains a novel protein source

Switching to a protein that your cat has not eaten before can help with your pet’s food sensitivities. Sometimes, cats are allergic to certain proteins found commonly in commercial cat food.

These include eggs, chicken, and even fish in some cats.

A novel protein source such as quail, duck, turkey, or rabbit can prevent diarrhea, vomiting, and other allergy symptoms in cats.

C) Contains limited ingredients

Select a food that is minimally processed and free from allergens like starch, gluten, carrageenan, corn, wheat, soy, and dairy which irritate the intestines and result in diarrhea.

D) Contains moisture

Many pet parents prefer high fiber wet cat food for diarrhea. This is because of the higher moisture content that aids in digestion of food, elimination of wastes, and lubrication of tissues.

High moisture content also serves as a medium that salts and other electrolytes use to pass through the cats’ GI tract.

E) Contains omegas and probiotics

Omegas and other essential fatty acids prevent inflammation of the GI tract. Probiotics are gut-friendly bacteria that increase the healthy microflora in your pet’s digestive system.

They aid in the digestion process and also increase immunity to diseases and infections.


The best high fiber cat food for diarrhea has a pacifying effect on irritation or inflammation caused by undigested foods in your cat’s tummy. It also helps eliminate wastes, keeps the GI tract clean, and creates less irritation and inflammation.

We recommend the PURINA ONE High Fiber Adult Cat Food because of its pumpkin and other fiber content that has prevented loose stools and chronic diarrhea in many cats.

It also prevents hairball formation. Do check out our other recommendations as well.
