What Is The Best Cat Food For Firm Stool? Reviews and Complete Buying Guide

This may come as a surprise to some of you, but constipation is quite a common issue among cats. It occurs when the stool is either too firm or dry, making it difficult for your cat to expel it. This can cause a lot of pain and discomfort to your furry buddy.

If you leave it untreated, it can lead to megacolon which is a condition where your cat’s colon is so stretched that it can’t go back to its normal size.

Feeding your cat the right food can take care of this issue. Cat foods can be expensive, so you definitely don’t want to buy a product only to realize it doesn’t help with constipation at all.


To make things easier for you, we’ve compiled a list of the best cat food for firm stool to make your search a bit easier.

Your Guide to Buying the Best Cat Food for Firm Stool

Buying the right food can mean a huge difference for you and your cat. It doesn’t have to be a hassle though, here are some things to look out for.

Things to Consider When Buying Cat Food for Firm Stool

Given below are some important factors to consider before you purchase cat foods:

Organic Products

Most brands manufacture cat food that contains inorganic ingredients known as GMO that can actually harm your feline’s health. Such ingredients are foreign to your cat’s bowel movements and hence makes it hard to digest.

To protect your cat’s wellbeing, go for organic cat foods as often as possible. I’d recommend you to opt for cat foods that are specialized for diarrhea and sensitive stomachs.

Protein-Rich Food

Just like us, a protein-rich diet is essential for your cat’s health. Not only does it promote your cat’s overall health, but it also improves its muscles and bones. Plus, it’ll pass through your cat’s digestive system with ease.

Typically, a high-protein diet will greatly improve a cat’s bowel movements, especially if it suffers from irritable bowel syndrome (IBD). Another point worth noting is that it’s best to reduce high-fat consumption as it causes colitis in cats.

Essential Nutrients

While proteins are an essential ingredient in your cat’s diet, your cat also needs certain nutrients. Vitamins like A, C, and E  will improve its digestion.

Essential nutrients like probiotics and fiber are great for your cat’s digestive system as it helps your cat to digest easily. This ensures them to pass stools without discomfort.

Fewer Ingredient Foods

Go for products that have few ingredients in it. Remember that most of the best cat foods are packed with only a handful of ingredients. Aside from that, food products with fewer ingredients reduce the chances of your cat from having any food allergies.


Cats are carnivores in nature and feeding them products that contain grains can cause digestive problems. You’ll notice an improvement in your cat’s bowel movements once you eliminate rice, corn, and wheat from their diet.

Instead, go for carbohydrates like pumpkin or sweet potato, such ingredients are easier on their stomach.

Avoid Dairy

Most cats are lactose intolerant which means that their stomach can’t really process dairy foods. If a cat is fed dairy, it may result in an upset stomach and diarrhea.

Whenever possible try to avoid dairy products.

Why Does Your Cat Have an Upset Tummy?

There are several factors that could cause your cat to pass loose stools. While some cases are mild, there are also serious causes that need immediate medical attention.

Some of these factors are as follows:

  • Cancer
  • Bacterial infection
  • Irritable Bowel Syndrome (IBD)
  • Consumed dairy, bugs, grass or chocolate
  • Changes in their diet or allergic reaction
  • Intestinal parasites

It’s not always possible to control what your cat consumes, but by changing your cat’s diet, you can improve its digestive health and ensure a firm stool.

While providing your cat with the best diet is an ideal option, it’s always best if you consult with a Vet first. If your cat has diarrhea, there’s no need to panic at all. Observe your cat and if the diarrhea persists, it’s best to get  professional advice immediately.

Feed Your Cat the Right Way

Now that you know what to look for when you purchase your cat’s food, the following tips will further help in improving your cat’s bowels.

Feeding your cat wet food specialized for digestive problems is totally fine. However, I’d suggest you go for dry food as it can get absorbed in your feline’s digestive systems without any complications and hence reduces diarrhea.

Avoid giving your food any foreign food, go for fiber supplements and charcoal-activated treats.

When your cat has diarrhea, make sure it remains hydrated. Also, check if the water is clean as contaminated water can further aggravate its tummy.

If you take your cat with you while traveling, be sure to get a packed bottle and cat food as well in order to soothe their digestion.

Don’t feed your cat a large meal in one go. Instead, try feeding it 3 smaller meals per day. Sometimes, overeating can cause your cat to pass loose stools.


Q: Can feeding raw food cause loose stools?

Feeding your cat raw food can have its benefits. However, feeding commercial dry foods and kibbles works better for domestic cats.

That’s because sometimes raw food lacks certain nutrients and is instead packed with ingredients that may be hard to digest.

Q: Is diarrhea serious for cats?

While it’s normal for cats to have diarrhea, if it persists for more than a day, it’d be best to take your cat to the vet immediately.

Q: What should good cat food contain?

Most of the good quality cat foods contain essential amino acids, minerals, vitamins, and fatty acids.
