High Fiber Cat Food

Regardless of who you ask, about your cat’s optimal diet, you will get an answer that is along the lines of moderate carbs and fat but high in proteins.  

However, a little while back, I decided to go through the list of ingredients in my cat’s food while at the store. I noticed something different; there were some cat foods that contained fiber and some that didn’t. This got me thinking. Why did some brands include fiber and others omitted it or included it only in small amounts? Does my cat even need fiber in her diet to be healthy?

Armed with all these questions, we started out research. We were amazed at the options available. But before we dive into the options, let’s have a look at some of the health benefits of fiber in your cat’s diet, types of fibers and factors to consider when choosing the best high fiber cat food.

Important Points to Consider

Below are some of the significant factors you ought to consider when buying:

  • Quantity of Fiber - Many people who stumble on fiber rich cat food think that in itself it is enough for their pets. But take it from me, it is not. Your cat requires more nutrients to maintain a healthy body. As a matter of fact fiber is required in very small amounts between 3-5%. Do not fool yourself into thinking that the more fiber you feed your cat the stronger and healthier it will be. On the contrary, as earlier pointed out, the effect may be quite the opposite.
  • Extra vitamins and nutrients - Cat foods rich in fiber help in fighting against diabetes and constipation. They also help in managing weight and reduce the risks of cancer in cats. But besides these, cat food should also contain extra nutrients including vitamins as well for an all-round healthy cat.
  • Age of Cat - Speaking of nutrients and vitamins, when considering the ingredients, you should also bear in mind the age of your cat. Kittens are playful and need a lot of energy to grown and play. As such foods rich in proteins and fats as well is critical. For old cats, high protein content will work fine as they only need it for muscle repair.
  • Price - The cost of the high fiber food matters a lot. As such, if your cat suffers from severe health issues like diabetes, you will want to feed her on the best quality food there is right? However, in the case of some regular health problems, you can do by serving her with a consistent good quality product. Truth be told, feeding a cat on the most expensive high fiber cat food can prove to be a burden (unless of course you are loaded, then it really is not a problem).

Types of Fiber in Cat Food

Now you have read the reviews of some of the best high fiber cat foods, it is important to understand the different types of fiber there are. Fiber in cat food is split into two categories; non-fermentable fiber and fermentable fiber.

Now, all dietary fiber your feline will absorb will be from the carbs it feeds on (most of it anyway). Very little fiber content comes from fat or proteins. As a matter of fact, in comparison, it is almost negligible.

Carbs are broken down into two; simple carbohydrates and complex carbohydrates. You want your cat food to contain complex carbohydrates if you are serious about feeding your cat on high fiber cat food.

Some of the complex carbohydrates present in most cat foods include fruits such as berries, pears and apples, vegetables such as tomatoes and carrots and some whole grains including brown rice, which is by far the most popular high fiber cat food ingredient of all.

Going back to the different types of fibers your cat will absorb from the high fiber cat food, fermentable fiber can be broken down by your cat’s digestive system with ease. With non-fermentable fiber, your cat’s digestive system will break it down, but only a small portion of it.

Note that for a cat to break down and absorb non-fermentable fiber, the body uses a lot more energy compared to breaking down fermentable fiber.

When I decided to feed my cat on high fiber cat food daily, after a few weeks, I started to notice that her pooping became regular, frequent and increased in mass. Gross I know, but I was ecstatic about the whole phenomenon.


Yes, it is true that your cat needs to be fed a diet rich in proteins. This is most critical for kittens. Your vet may advise otherwise depending on the prevailing condition of your cat. but generally, a diet rich in proteins is advised.

This, however, does not negate the importance of high fiber cat food. On the other hand, this piece is not to say that you should sacrifice or replace a diet rich in proteins with one high in fiber – find a balance. Here is a breakdown of the benefits your cat stands to yield.

Upset Tummy & Runny Poo

These two are the number one reasons why most cat parents decide to feed their little bundles of joy with high fiber cat food. Fiber helps in solidifying poop and eases the digestive system back to its normal functioning. It also helps in making pooping trips more frequent, easier and regular, especially for the cats that are constipating.

If this is the reason you are considering cat food, you should prefer wet canned high fiber cat food instead dry high fiber cat food. This is especially if your cat is constipating. The moisture present in the food will go a long way in easing your cats discomfort.

Note that overdoing a fiber diet can prove to be counterproductive of the goal you are trying to achieve. It might lead to malnutrition as the absorption of other important nutrients including minerals and vitamins will be hindered.

Weight Management

Obese or overweight cats are all too common. My very first cat grew obese as a result of feeding it with a diet full of fats (bad fats). By the time I found a solution to the situation, things had already gone from bad to worse and it was too late.

How and why does a diet rich in fiber work? It is simple, and actually, it is the same principle that applies to man and dogs as well. High fiber foods result in the consumption of fewer calories throughout the day since they give the feeling of a full stomach for longer.

That said, I should stress the need to speak to your vet before settling on any fiber related weight lose plan for your cat. Only a vet can guide you on the plan of action and whether your cat requires to undergo the weight loss in the first place. Exercising can work pretty well too. Speaking of which, here are some fun exercise equipment you could get your cat. These include cat trees and tunnels. For cat trees, consider, the Songmics Cat Tree Condo, and for the tunnels consider Prosper Pet Cat Tunnel

Kills Cancer

High fiber foods are believed to help in reducing the risks of certain cancers in humans. They have the same effect in cats as well. The strength or the risk reduction may not be as that experienced in humans but it is a possibility all the same.

Blood Sugar Regulation

If your cat requires blood sugar regulation courtesy of say, diabetes or hypoglycemia, high fiber cat food will play a huge role in the regulation. The carbs present in high fiber cat foods are complex and these require more time to be broken down and absorbed in the body. This in turn results in more stable blood sugar levels and keeps your cat’s system from crashing.


And there you have it. Above are some of the best high fiber cat food for both constipation and diarrhea.  Feeding your cat with any of these foods will help keep your cat healthy and give them more energy.

But that said, I should point out that there are some alternatives to high fiber cat food. One perfect alterative includes a water fountain. When your cat constipates, it only means that they do not have sufficient water in their system. And since cats do not love drinking still water, you can involve them by adding a cat water fountain. This will trick your feline to take more water and keep constipation at bay.
