Bag[/amalinkspro]

This product is made for urinary and kidney issues, both for light treatment and prevention, but it also improves digestion in several ways.

The first way is by low ash content, which results in healthier stool formulation. Secondly, it balances the mineral intake so none of the minerals can easily build up in your cat’s body. This protects our cats from some minerals inhibiting the absorption of other very important minerals, which can affect the overall gastrointestinal function.

Finally, chicken is the first ingredient in producing this product, which means the majority of protein comes from an animal source. This indirectly improves and maintains bacterial cultures in a cat’s intestines, and improves their overall health.


  • Protein: 32%
  • Fat: 15%
  • Carbohydrates: N/A
  • Probiotic culture: Yes
  • Chicken is the first ingredient
  • Balanced fat/protein content
  • Also helps with urinary problems
  • Not as tasty to cats
  • High in calcium and potassium

Buyer’s Guide

When looking for the best cat food for firm stool, there are several things you should consider.

Is Your Cat Healthy?

There are plenty of reasons why your cat may have stool problems. Some of these are:

  • Bad diet
  • Cancer
  • Stress
  • Bacterial disbalance
  • Parasites in the intestinal tract
  • Allergic reactions
  • IBS (Irritable Bowel Syndrome)

As you can see, there are some issues dietary correction can solve, and others need close veterinary attention. Consult your veterinarian if you’re unsure what’s causing your cat’s loose stool.


Good cat food contains fiber that improves the cat’s digestion. They keep the food in the digestive system longer, prolonging absorption time.

Fibers also help with the consistency of the stool and the ease of stool evacuation. Cat food that has a well-balanced mixture of different fibers will help your cat poop much easier. These fibers will also increase the number of nutritional goodies the cat takes from its food.


Protein is another essential element of good dry cat food. There are several different types of protein present in various products. The products that contain animal protein in the majority will be much more beneficial than those that pack protein percentage with plant-based protein.

A cat’s intestines aren’t built for absorbing heavy plant-based protein that well, and once absorbed these proteins can impact the liver. They also don’t nourish the good bacterial flora in the intestines, leading to diarrhea or constipation.

Bacterial Cultures

You can also check for the bacterial cultures in the product’s ingredients section. The more bacterial cultures are listed in this section, the better. These are good bacteria that help break down complex compounds like proteins into simpler, more absorbable compounds, like amino acids.

Healthy bacteria maintain healthy intestines and make sure the process goes in the most natural way possible. They’re also a source of healthy nutrients and the reason your cat has a healthy stool.


In our research, we’ve found that the Science Diet Indoor Chicken recipe is the best cat food for a healthy digestive tract, which is reflected in a healthy stool. It’s rich in all the necessary nutrients while, at the same time, helps maintain healthy bacterial cultures in a cat’s digestive system.
