High fiber cat food reviewed (2018)

Looking for high fiber cat food? Because cats are obligate carnivores, you wouldn’t think that they would need extra fiber in their diet, and the majority of the time they don’t- feline bodies are not meant to digest fiber, and they will ferment it first so that they can digest it. However, occasionally you may come across a health concern where your cat may need a little extra fiber in their diet.

The most common problem fiber helps with is constipation and diarrhea. The right amount of fiber controls the balance of water in the stool, thus making your cat have what we would call a normal bowel movement. Fiber is also good for weight loss and weight control. This is because the slowly fermenting fiber takes longer to digest, giving the cat the feeling that it doesn’t need to eat anymore than it has to.


This is why you see so many diets that are high in fiber and low in calories. This also indirectly helps prevent diabetes, because one of the most common causes of diabetes in cats is obesity. Also, diets high in fiber lessen blood glucose spikes.

It is also possible to give your cat too much fiber, which can cause a whole host of problems as well particularly if it is non-fermentable fibers. A cat food rich in non-fermentable fibers can cause your cat to have hard, dry stool and constipation, and severe gas. It can also hold water and prevent its absorption, which can increases the amount of feces and frequency of pooping. The problem is finding the right balance of fiber for your cat’s needs, which is sometimes easier said than done.

The easiest way to add fiber to your cat’s diet? Canned pumpkin. Yes, plain old canned pumpkin. Add a teaspoon or so to their wet food, mix it in and you are good to go. But what if your cat does not like the flavor of pumpkin? Some cats are very picky eaters and will turn their noses up at anything from the way it tastes, smells, or even the texture! If your kitty is one of those, then keep reading- we will discuss how to find the right high fiber cat food for you below.

When looking at cat food, you want what is known as “good” fiber- this is the slowly fermenting fibers that cats are able to digest such as that found in soybean, oats, and rye. Non-fermentable fibers are fibers that ferment quickly such as fibers found in flax seeds, whole grains, and corn. It is best to get a good mix of both in the diet, but many lower quality cat foods have a higher percentage of non-fermentable fibers, which is not good for your cat’s intestinal tract. When you read the labels of cat food, first look at the ingredients for the types of fiber that is in the product. The higher up an ingredient is on the list, the more of the ingredient is in the food. If corn, grains, etc., are high on the list then pick a different food.

Having said that, I must warn against feeding a purely dry food diet as it is one of the worst things you can do for your cat. Male cats that are on a purely dry food diet are more likely to develop urinary crystals by the time they are 5-6 years old, which can block the urethra and cause life threatening urinary blockages if gone untreated. Female cats are just as likely to have crystals develop, but less likely to have the crystals block the urethra. Instead, the crystals could develop into bladder stones which could be just as harmful. Wet food is about 70% water, so if you feed your cat a purely wet food diet, then your cat will be very unlikely to develop urinary crystals or stones.

Dry cat food is also extremely calorifically dense, which means that you won’t need to feed very much to make sure that your cat gets the right amount of calories for the day. This is good for your wallet but leaves your cat hungry! This is one of the many reasons why you should consider feeding your cat a mostly wet food diet. Dry food may be super convenient, but it is certainly not a healthy route to take your cat down.
