Best Cat Food for Diarrhea

If your cat has acute diarrhea, a bland diet will help them return to normal. In most cases, chronic diarrhea necessitates a dietary change.

Like diarrhea in any other species, your cat’s diarrhea might be a symptom of serious illness or could be a short-lived reaction to a new food.

The cause of your cat’s diarrhea informs the appropriate dietary response. Before we review the top 5 best cat foods for diarrhea, let’s examine the differences between feeding a cat with acute diarrhea and one with chronically loose stool.

Acute diarrhea is a temporary reaction to GI irritants.

Acute diarrhea happens when your cat drinks a saucer of milk, has a bad reaction to something they ate, or is dealing with an infection.

If your cat looks and acts sick, you’ll want to take them to the veterinarian. If they’re bright-eyed and playful, a day or two of diarrhea isn’t cause for concern.

If the following symptoms accompany your cat’s diarrhea, a vet trip is in order:

  • Lethargy
  • Inappetence
  • Dark, tarry stools
  • Dehydration
  • Vomiting
  • Extreme diarrhea

Remember that diarrhea alone can be life-threatening for sensitive populations. If your cat is a particularly fragile kitten, elderly, or infirm, diarrhea may necessitate a vet visit. These cats are at a high risk for dehydration and a bout of diarrhea could wipe them out.

Severe diarrhea could make your cat dehydrated. This video shows you how to test for dehydration:

Feeding a Cat with Acute Diarrhea

If your cat has acute diarrhea due to illness or eating something they shouldn’t have, you don’t necessarily need to change their diet. After their stool returns to normal, you may return your cat to their familiar food.

Here’s what to do in the meantime.

First, fast your cat.

Give your cat 12 hours without food to give their digestive tract a break. Diarrhea impedes nutrient absorption, so don’t fear that you’re depriving them.

After 12 hours of fasting, switch to a bland diet.

The classic protocol is a regimen of cooked chicken and rice, but there’s no need for rice. Cats are obligate carnivores and do best on a meat diet, regardless of their stool consistency.

A diet of salt-free boiled and defatted chicken, pork, or turkey meat with broth will temporarily nourish your cat without aggravating their GI tract. Remember that this bland diet isn’t nutritionally complete and isn’t safe for feeding your cat for more than a couple of days.

Supplement with probiotics.

The gut microbiome can be considered an organ of its own. It plays a key role in digestion, the immune system, aging, inflammation, and almost every aspect of health. Probiotics help to fortify the natural gut flora and restore healthy intestinal function.

Consider using slippery elm bark.

This bark has multiple benefits for cats with diarrhea. It soothes pain, eases nausea, and can normalize stool consistency.

You may also supplement with pumpkin.

While it’s a lightweight compared to slippery elm bark, pumpkin is a classic food additive for cats suffering from diarrhea. Many people swear by it. It’s a palatable, easy-to-find source of soluble fiber, which can help to bulk up your cat’s stool. Choose canned pumpkin puree with no added spices or sweeteners.

Chronic diarrhea continues for weeks or more and may manifest as part of an issue generally referred to as a “sensitive stomach”.

Chronic diarrhea occurs intermittently or consistently for more than 3 weeks.

This condition could stem from allergies, food intolerances, or inflammatory bowel disease.

If your cat has chronic diarrhea, a trip to the veterinarian is a good idea. The vet can run diagnostic tests to determine the cause of your cat’s endless loose stool.

Diet change is necessary in almost every case of chronic diarrhea.

Feeding a Cat with Chronic Diarrhea

Identify allergens and sensitivities by putting your cat on an elimination diet.

This stripped-down diet eliminates those familiar ingredients that may have triggered your cat’s diarrhea and replaces them with novel proteins. If your cat’s diarrhea vanishes while on the elimination diet, you can re-incorporate ingredients one-by-one to determine which one caused the symptoms.

Provide species-appropriate food.

Minimize inflammation by giving your cat a species-appropriate diet centering around fresh muscle meat and organs. Ingredients that aren’t species-appropriate aren’t efficiently utilized by your cat’s body. By providing a high-quality, meat-based cat food with minimal carbohydrates, plant protein, and irritating additives, you lessen the burden on your cat’s GI tract.

Minimize dysbiosis by fortifying your cat’s gut microbiome.

Gut dysbiosis—an imbalance of good and bad microorganisms in the gut microbiome—is a major factor in chronic diarrhea. To manage your cat’s diarrhea, fortify those “good” populations by administering probiotics.

While most probiotics can help, the S. boulardii strain is the gold standard for cats with diarrhea. This probiotic yeast is impervious to antibiotics and has well-known antidiarrheal properties.
