Best Cat Food For Firm Stool

Cats as well as humans can suffer from diarrhea from time to time, especially as they get older and become more susceptible to conditions such as inflammatory bowel disease. This can lead to toilet time being a particularly painful process for your kitty and can lead to further complications later on.

Although there might be no way to cure your cat of these digestive ailments - once a chronic illness has developed all cats will experience bouts of pain and diarrhea throughout their lives - you certainly can alleviate the pain and discomfort experienced by them. One of the main ways is by finding the right diet.

Finding the correct foodstuff for your feline is always tricky. Every cat has an individual preference and it is not uncommon to see cats turning their nose up at certain foods laid out for them.

So when it comes to finding a new cat food, you’ll want a brand that perfectly balances taste with nutrition, something that is easily-digestible, fortified with probiotics that increase the healthy bacteria in your cat’s gut.

You’ll also want something that has plenty of fiber and protein, which will be important for achieving those solid, healthy stools.

But what ingredients are essential for giving your cat healthy digestion? How can you avoid artificial preservatives and meal by-products that could be potentially very harmful for your cat’s stomach and bowel? How much will good cat food cost?

Well, we’re here to answer some of those nagging queries and get your feline friend back on their feet with healthy-looking excretions.

We’ve compiled a list of a few of the best cat foods for digestive health currently on the market, along with some of the do’s and don’ts for purchasing new cat food and some frequently asked questions from concerned cat owners.

Best Cat Food For Firm Stool Buying Guide

If your cat is suffering from diarrhea, it is very important to isolate the causes as quickly as possible to find the most effective treatment, allowing time for switching between different cat foods as well as time for digestive recovery.

First off, it is worth highlighting the differences between different forms of diarrhea.

What Is Acute Diarrhea?

This type of loose stool only lasts a few days and is the result of a minor irritation in the bowel, usually caused by an irritant or an illness. Your cat might develop acute diarrhea after eating a cat food that does not agree with them.

A cat suffering from acute diarrhea doesn’t necessarily need a switch in diet, you simply wait for their stool to return to normal and then switch back to their regular kibble.

Here are a few tips for dealing with acute diarrhea:

  • Don’t feed your cat for 12 hours. This will give the cat’s digestive tract a break. Diarrhea reduces nutrient absorption anyway, so this fasting won’t be too harmful to your cat.
  • After this, switch to a bland diet. Unseasoned salt-free cooked chicken and rice will suffice. You should only feed them this diet for a few days.
  • Supplement this diet with probiotics. This will fortify the natural gut flora and hopefully bring the intestinal functions back to normal.

What Is Chronic Diarrhea?

This type of diarrhea occurs intermittently for a few weeks and can require significant changes to a cat’s diet. Once seen by a vet, they will often determine that the cat has a ‘sensitive stomach’. This diagnosis could be the result of many things, including allergies, food intolerances or IBD.

Here are a few tips for feeding a cat with chronic diarrhea:

  • Strip down your cat’s diet so you can identify any allergies or sensitivities. Certain ingredients may have triggered your cat’s sensitivities and the only way to determine these will be to eliminate them.
  • Feed the cat a simple, carnivorous diet of muscle meat and organs, such as chicken, pork and turkey.
  • Fortify your cat’s gut microbiome by supplementing its diet with probiotics.
