After studying how much fiber cats need, identifying appropriate fiber sources for cats, and researching the high-fiber cat food market, we recommend Weruva Cats in the Kitchen Funk in the Trunk Chicken in Pumpkin Consomme as the best high-fiber cat food on the market.
Most high-fiber foods—think those marketed for indoor cats and hairball control—are bulked up with fiber and other plant ingredients your cat doesn’t need. Too much fiber and too much plant matter can give your cat a smelly litter box and a troubled tummy. That’s the opposite of what you want.
The best high-fiber cat food supports your cat’s need for a carnivorous diet and provides just enough fiber to keep his gut healthy without weighing him down.

Top 5 Best High-Fiber Cat Foods
The foods that are described below provide a little extra fiber while honoring your cat’s carnivorous needs.
On top of fiber content, they have essential qualities like plenty of species-appropriate animal protein, high moisture content, and minimal carbohydrate matter. They’re made with safe, high-quality ingredients and are created by reputable companies. Some are formulated with digestive health in mind, offering additional support for a smooth move through the digestive system.
The Right Amount of Fiber Can Promote Healthy Digestion, but Don’t Overestimate the Need To Add Fiber to Your Cat’s Diet.
Cats are carnivores who live on flesh, fat, and bones. The natural feline diet doesn’t involve cellulose powder, dried tomato pomace, or flaxseed. In contrast to the fiber fermentation machines that are herbivores, cats have short digestive tracts and their bodies don’t spend much time fermenting what they eat.
But they do need a little fiber. When cats consume prey in the wild, they ingest all sorts of indigestible matter—hair, claws, teeth, and connective tissue. Though it’s not fiber in the traditional sense, this indigestible stuff ferments in a cat’s colon and aids digestion. Since most people are unable or unwilling to add back this indigestible animal matter, plant fiber works instead.
Both soluble and insoluble fiber help to promote healthy digestion. They feed good bacteria in the gut and help the stool retain water. A little bit of fiber is essential to keep your cat’s gut happy and healthy.
While a pinch of fiber is a friend for your cat’s GI tract, there’s no need to fill your cat up with piles of fiber. In fact, most normal dry foods—not even those marketed as high-fiber or indoor foods—have more fiber than a cat’s natural diet would ever include. A cat’s natural diet of fresh, whole rodents would be about 0.55% fiber. Compare that to the 4% fiber content of a standard dry food or the 9-10% fiber content of the typical indoor cat food.
On top of the fact that most cat food has more fiber than cats need, cat food companies market fiber as a solution to problems that it either isn’t the best solution to or simply can’t solve.
For example, although fiber helps promote fullness, your overweight cat may not need a high-fiber diet to stay satisfied and lose weight.
If he’s already eating a normal diet, your hairball-prone cat doesn’t need more fiber to sweep hair through his digestive tract. Fiber is not a broom and your cat doesn’t need to be swept like a kitchen floor. It’s normal for cats to eat hair, whether it’s their prey’s hair or their own. That hair moves through the GI tract and comes out in the stool. That’s normal. Frequent hairball hacking is indicative of deeper digestive problems, not a fiber deficiency.
Too much fiber could inhibit the secretion of pancreatic enzymes that digest protein, decreasing nutrient absorption and, ultimately, making your cat less healthy. Elisa Katz, DVM says that she’s seen this problem “in many cats fed a commercial prescription diet known to be high in fiber. Their coats become dry and flaky and their stools become huge.”
If, after switching your cat to one of the above foods or something similar, your cat is still having digestive issues, more fiber isn’t the answer. There are likely deeper issues at work.
Speak with your veterinarian if you are thinking about switching your cat to a high-fiber food. Your veterinarian will consider your cat’s overall health and current diet to determine whether a high-fiber food would be right for your cat.
