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.

This article is really helpful in finding a new diet for my 4 cat household. I did want to note that the ingredient list for the Weruva was incorrect. Thank you!
Lani, thank you so much for making us aware of that! I’ve corrected the ingredient list.
Are you paid by these brands? Checking the crude fiber vs dry matter content, some of these actually very LOW fiber content -much lower than other brands, in fact. A very common fiber content is 1%-1.5% crude fiber in 78% moisture foods, which is 6.8% fiber based on dry matter content. Seeing brands on here that are 0.5% to 80%+ moisture brands is misleading. My vet has advised that true high fiber foods are in double-digits in terms of fiber as a percentage of dry matter – prescription high fiber foods are 14%+.
Hey Julius, no! We’re not paid by these brands. As the article mentioned, I chose not to list extremely high-fiber foods, because I found that most of the cats who are given high-fiber foods (like those with constipation and hairballs or overweight cats) don’t benefit as much from a very high-fiber diet as they do a species-appropriate diet with moderate levels of fiber. The products listed here are slightly higher in fiber than other similarly high-protein, carnivore-appropriate foods, and they have other qualities that may support satiety and digestive health as well. I realize that this may make the title seem misleading, but I think this is the most helpful approach. Your vet may have a different opinion on this, and we always recommend bringing these questions to a vet rather than taking our word for it.
You are correct in that the title is misleading which makes this article disappointing. Had I not read the comments I’d still be wondering what I’m missing in that the fiber isn’t that high in these brands. Why not give us what the article promised and let us make decisions for what our cats need right now? Don’t treat readers like we’re children that you have to protect from ourselves.
This is a good point, Liz. I’m still happy with the message of the article, but we’ll keep this in mind for the future.
I did not find the title misleading and absolutely never felt I was being treated as a child. The title stated “ BEST” High Fiber Food as opposed to simply Highest Fiber Food. From my research I agree that these are considered some of the “best” options for increasing fiber while maintaining good protein and other healthy ingredients for cats, just as the article explains. They did state in the article that there ARE higher fiber foods but that there are reasons that those higher fiber foods may not be best for cats. The title fits the article just fine.
Loved finding your website, So much info, I left my vet so overwhelmed on what food to feed my 2 – 13 year old cats, none of which they would eat. Needing food to feed one who is a diabetic and the other one has constipation. I would love to find a food that would serve both needs as they are hard to keep out of each other’s bowls and like to sneak each other’s like their missing something. Any recommendations?
Hi Vicki! We have some information about choosing cat food for diabetic cats (and recommendations) here:
https://cats.com/best-cat-food-diabetic-cats
Unfortunately, diabetic cat foods tend to be low in carbs while cats with constipation can benefit from higher levels of fiber. One thing to try might be adding pumpkin puree to the food. It’s a low-carb source of fiber that will also add a little moisture. Other sources of additional moisture can be beneficial for both cats as well. Supplementing dry food with a high-protein, low-carb wet food is great or just mixing a little bone broth into the food. Bone broth has digestive benefits as well.
