High fiber cat food buyers guide

Cats are obligate carnivores and they do best when eating animal proteins and fat. Their natural diet doesn’t include fiber, as a cat’s digestive tract is fairly short and not equipped for food fermentation.

However, felines still need a certain amount of fiber in their diet. In the wild, cats eat prey, which contains hard-to-digest matter like teeth, claws, and fur. Since much of it goes undigested, it has the same function as fiber.

Fiber is a type of plant-based carbohydrate that the body can’t break down and digest. Instead of breaking down, fiber helps food move through the digestive system and can help maintain stool quality and gut health.

Commercial cat foods contain different types and amounts of fiber, and the best option for your kitty will depend on their individual needs.

The following tips will guide you in the right direction during your search, but be sure to consult the vet before any purchase.

Your vet will be able to provide more details on the right type of dietary treatment for your cat.

Here are some things to bear in mind while looking for high fiber cat food.

Types of fiber

There are two types of plant-based fibers – soluble and insoluble.

  • Soluble fiber: is rapidly fermentable and it dissolves in water. This type of fiber is found in pectins and gums and it can help with constipation.
  • Insoluble fiber: is slowly fermentable and it doesn’t dissolve in water. It makes the food move slower through the intestine, resulting in a bulkier stool. Insoluble fiber includes cellulose and peanut hulls and it can relieve diarrhea.

Both soluble and insoluble fibers can be beneficial for your cat’s digestive system, depending on their needs. There is not enough research to offer conclusive evidence about the full effect of fiber on a cat’s body.

Some experts suggest that insoluble fibers like cellulose slow down the movement of food through the intestine. But a 2016 study showed that cellulose reduces the gastrointestinal transit time and may push the food through the digestive tract too quickly, not giving enough time for nutrients to be properly absorbed.

When in doubt, you can always pick food withmoderately fermentable fibers- they have both types and include bran, soy fibers, and beet pulp.

The amount of fiber

The natural diet of cats, consisting of animals like birds and rodents, contains approximately 0.55 percent fiber.

The amount of fibers in some commercial cat foods can be much higher, even going up to 10 percent. The reason for this could be the lower cost of plant-based ingredients compared to other types of ingredients.

Pet food labels can be misleading when it comes to fiber content. The labels show the amount of crude fiber, but this only measures the amount of insoluble fibers.

Depending on the type of food, the total amount of fibers can be much higher, especially if the food also contains sources of soluble fiber. Be sure to ask your vet for advice on optimal fiber intake for your kitty.

Protein content

The amount of fiber used in cat food shouldn’t replace protein content.

Cats are obligate carnivores and they require animal-based protein in their diet. Be sure to pick foods that are rich in meat and animal proteins.

Carbs and calories

High fiber cat food is often intended for cats with diabetes or obesity problems, so it may have low carb and low calorie content. But you need to take your cat’s specific needs into account.

For example, if your kitty is underweight and has diabetes, they may struggle to eat enough low calorie, high protein food to achieve optimal weight.

The amount of carbs and calories in a particular food are also important factors to consider before you make a purchase.

Omega fatty acids

If your cat has hairball issues, be sure to pick food rich in Omega-6 and Omega-3 fatty acids. They support healthy skin and coat and reduce shedding, consequently reducing the risks of hairballs forming.

Why should you feed your cat high fiber food?

Cats with digestive health issues benefit most from a high fiber diet. Some common digestive issues are:

Constipation and diarrhea

As we’ve already mentioned, soluble and insoluble fibers can help your cat combat constipation and diarrhea, respectively.

Soluble fibers add moisture to your cat’s stool, making it softer.

Insoluble fibers have the opposite effect – they slow down the food transit, which results in a bulkier stool.

Hairballs

Cats often have hairball issues, and they can cause intestinal obstruction.

Research has shown that fiber can be effective in reducing the production of hairballs. A study involving 21 adult cats found that psyllium (a soluble fiber) minimizes hairball formation in 14 days and between shedding periods.

Weight loss

Although there is a popular belief that high fiber diets can help obese cats lose weight, there is still no scientific evidence to support this claim.

High fiber foods often have low carb and low caloric content, but the effect of fiber itself on weight loss still hasn’t been researched.

Diabetes

Dietary fiber can keep blood glucose levels steady to a degree, minimizing the effect of frequent highs and lows.

Research suggests that commercially available high fiber food can lower glucose levels in cats with naturally acquired diabetes mellitus.

How can I add fiber to my cat’s diet?

It’s important to consult your vet on the best way to add fiber to your cat’s diet. Based on your cat’s needs, your vet will be able to prescribe a therapeutic diet with higher amounts of specific types of fiber.

What is good fiber for a cat?

Soluble, insoluble or moderately fermentable fibers can be beneficial for your cat’s digestive health, depending on their individual needs.

Be sure to work with your vet to determine both the type and the amount of fiber your kitty needs.

Is a high fiber diet good for cats?

While cats with digestive issues can benefit from increased fiber intake, incorporating large amounts of fiber in your cat’s diet for no reason can be harmful for your pet.

Too much fiber can reduce the secretion of pancreatic enzymes necessary to digest protein.

Compared to other mammals, cats already have a lower number of such enzymes, and large amounts of fiber could prevent proper nutrient absorption and endanger your cat’s overall health.

Key takeaways on high fiber cat food

Cats need small amounts of fiber to support digestive health.

Certain felines may require increased amounts to combat health issues such as diarrhea, constipation, and hairballs. For cats with chronic illnesses like diabetes, fiber may also help lower their glucose levels.

Blue Buffalo Blissful Belly Natural Digestive Care Dry Cat Food is at the top of our list – it provides your kitty with high-quality protein and hydration, while including prebiotic fiber that’s gentle on the stomach. It’s a perfect option for cats with sensitive tummies that need help with regulating stool.
