Fiber is the answer to most of the digestive issues that cats face from diarrhea, constipation, and sensitive stomachs. 

As obligate carnivores cats generally have a high urge for meat and fats, and they obtain most of their nutrients from these sources since they cannot get them from plant sources.

Providing a high fiber diet to your cat does not mean that you are sacrificing their regular dietary proteins, instead you are supplementing the protein in their diet with a fiber component.

This article discusses the benefits of higher fiber in your cat’s diet, how to get more fiber in their diet, and what benefits this provides for your cat.

Do Cats Need Fiber In Their Diet?

Cats often avoid the plant fiber of the intestinal contents of their prey, which is rich in crude fiber.

Veterinarians recommend adding a little fiber to a cat’s diet or transitioning to a fiber-rich diet.

However, this does NOT mean replacing the high-protein, high-fiber diet with a fiber-only diet.

Benefits Of A High Fiber Diet

While it is true that excess fiber can cause problems in cats, it is also true that some high fiber formulas can help cats in some body functions.

You can supplement the regular diet with a diet rich in fiber, rather than transitioning your cat to a fiber-only diet.

You can also introduce a rich-fiber diet on the recommendation of your vet. 

Fiber is important for the following reasons:


High fiber diet has been touted as an effective treatment for constipation.

If you notice your cat having infrequent bowel movements or being unable to pass stool, a high fiber diet is a good temporary solution.

Apart from giving your cat a high fiber meal, make sure they drink fresh water, and meals with a high moisture content (canned cat food is a perfect option).

Diabetic Cats

For cats with special conditions like diabetes and hypoglycemia, a high fiber diet helps in regulating the cat’s blood sugar levels.

The diet contains complex carbohydrates that take a longer time to be broken down and absorbed by the cat’s body.

This results in more stable sugar levels, thereby reducing the frequent spikes of unwanted blood sugar in the cat’s body.


A fiber-rich diet helps ease diarrhea by slowing digestion and adding bulk to stool.

Fiber tends to attract water and form a gel, which helps to strengthen the stool before it is passed by the cat.

How Can I Add Fiber To My Cat’s Diet?

Fruits, canned or cooked pumpkin and vegetables are great sources of crude fiber.

With your vet’s approval, add a bit of these ingredients to your cat’s current diet.

Vets recommend one teaspoon daily but divided into two meals. Make sure not to overdo it, since excessive fiber may have adverse effects.
