The Best High Fiber Cat Food and What You Need to Know

January 17, 2017

We know that cats are carnivorous animals and that their diets should contain a high level of good-quality protein. However, that doesn't mean cats shouldn't get any fiber in their diets. In fact, there are some very specific reasons why your cat may need a diet that is higher in fiber.

In this article we are going to explore those reasons, what you need to know about fiber-loading and the problems that can occur with a high fiber diet. In addition, we are also going to review the top six recommended high fiber cat foods on the market today.

What You Should Know About Fiber in Cat Food

Fiber and filler in a cat kibble is not the same. Lower-end cat food manufacturers use fillers such as corn and by-products to bulk up the kibble, making it less expensive to make; however, these fillers offer little to no nutritional value for your feline friend. Fiber, on the other paw, helps to regulate your pet's blood sugars, helps your cat feel full longer and helps to prevent constipation, along with other health-related issues.

There are two types of fiber; soluble and insoluble

Soluble Fiber:

  • Breaks down in water.
  • Maintains glucose levels.
  • Lowers blood cholesterol levels.
  • Helps prevent constipation
  • Can turn into a gel in the digestive tract to slow the digestion of sugars from other carbs.

Insoluble Fiber:

  • Does not dissolve in water.
  • Helps food move through the digestive tract.
  • Helps prevent constipation.

Why Does My Cat Need a High Fiber Cat Food?

There are a number of reasons why your cat may need a high fiber cat food. The most common are to manage your cat's weight, because of a gastrointestinal issue such as constipation and to help control a more serious health issue, diabetes. Let's explore these issues further.

High Fiber Cat Food for Weight Loss

As more pet parents are keeping their cats indoors to protect them from the risks and dangers of the big bad world, the more veterinarians are seeing an increase in cat obesity. Typical indoor-only felines tend to get lazy and lack the stimulation they need to keep their bodies as streamlined as they should be.

For this reason your veterinarian may suggest a low-fat, high fiber diet to shed those unwanted pounds. This plan works well in most felines as the higher fiber content found in these specialty foods fill the cat up faster and allows them to feel fuller longer. This works especially well if you have a cat that tends to mooch and pester when put on a diet where you just lower the portion size and the caloric intake.

A top high fiber cat food for weight loss is the Hill's Prescription Diet w/d Feline Low Fat. This dry kibble is formulated to maintain your cat's lean muscle while burning fat. It will also protect your cat's overall immunity system, while promoting its urinary tract health.

High Fiber Cat Food for Constipation

Just like when we are constipated and a big bowl of high fiber cereal or oatmeal does the trick, the same is true for our feline friends.

Fiber works to relieve constipation by absorbing water and making the stools looser and more buky. This causes the feces to move through the intestines more quickly. In addition to a high fiber cat food for constipation, be sure to always have fresh water available for your cat. You can also try adding some wet/canned food to your cat's daily kibble for an added moisture boost.

A top high fiber kibble for constipation is the Royal Canin High Fiber Veterinary Diet. This quality dry food provides added ingredients to help protect your cat's microflora and intestinal cells. It also increases the oligosaccharides (a carbohydrate with a small amount of sugar) to maintain the overall intestinal health of your cat. Plus, it has Omega-3 and Omega-6 fatty acids to help nourish your cat's digestive tract.

High Fiber Cat Food for Diabetes

Unfortunately, diabetes is on the rise in the feline species. A common denominator for this health issue is also obesity in cats. As we mentioned above, raising the fiber content in the cat's food will help your pet feel fuller longer and decreases his chances of overeating.

In addition, the high fiber content will slow down the absorption of glucose in the cat's body so it won't metabolize it so quickly. This in turn keeps your pet from experiencing those glycemic spikes that tend to occur after eating a regular cat kibble.

A highly recommended high fiber cat food for diabetes is the Hills w/d Low Fat Diabetic GI Health cat food. This product has high levels of carnitine (involved in fat metabolising) to help increase energy and to burn away extra fat. It also has added antioxidants for overall health and a moderately high fiber content to create that feeling of fullness.

What Are the Problems With a High Fiber Cat Food?

Just like a human eating a high fiber diet, your cat could experience a lot of flatulence and also more frequent bowel movements. Your cat may also not like the taste of these fiber-loaded products due to the fact the cats are carnivores and will seek out primarily a meat source.
