As a pet parent, you undoubtedly love your feline companion. You ensure your cat has frequent vet visits, is groomed properly, and has the best high-quality food you can afford. However, the first advice you get when asking someone about feeding a cat is to give them a high-protein diet.

Our choice of the best high-fiber cat food for the money goes to Iams Proactive Healthy Adult Cat Food for its affordability.

There are plenty of antioxidants in this food to make sure your dog’s coat is healthy and shiny. The formula’s prebiotics supports your pet’s digestion, and the crunchy kibble helps reduce plaque buildup to maintain your kitty’s dental health.

Although chicken by-products are an excellent source of protein, some pet parents mentioned they prefer brands with whole-meat ingredients, and others were disappointed the recipe contains corn gluten meal.

3. Iams Proactive Health Indoor Weight Control Cat Food – Premium Choice

Our premium choice of the best high-fiber cat food this year goes to Iams Proactive Health Indoor Weight Control Cat Food for its high protein content. Chicken is listed as the first ingredient in this food, and Proactive Health is a great source of protein, containing over 30%. The food includes fiber sources such as beet pulp to help reduce hairballs and relieve any digestive issues your feline might be suffering from.

There have been reports of Proactive Health causing constipation in some felines. Some pet owners have also said that the company switched the recipe, and their cats refused to keep eating the blend.

It has no artificial flavors, colors, or preservatives and has a healthy antioxidant and vitamin blend that supports your growing feline’s immune system properly.

Some of the food has been reported as having a foul odor, and some kittens won’t eat it.

5. Royal Canin Veterinary Diet Adult Gastrointestinal Fiber Response Dry Cat Food

We chose Royal Canin Veterinary Diet Adult Gastrointestinal Fiber Response Dry Cat Food for being balanced for good digestion.

8. American Journey Indoor Cat Food

American Journey Indoor Cat Food is designed primarily for felines that spend most of their lives indoors. Indoor cats are more vulnerable to gaining weight and becoming obese than outdoor cats, but American Journey’s formula has a healthy balance of fats and protein to help your pet maintain a healthy weight. American Journey Indoor has a 6% fiber content and is high in protein at 32%. The high-fiber formula also helps with hairball control, which many indoor cats struggle with.

Buyer's Guide: Reasons to Feed Your Cat High-Fiber Cat Food

Now that you know what the best high-fiber cat foods are for your feline, you might be wondering why it’s important to feed them a high-fiber diet. We’ll discuss the reasons in the buying guide below.

Diarrhea and Constipation

Diarrhea and constipation are hard on a cat. If your cat has either of these problems, it usually means that their digestive system isn’t working the way that it should. The fiber in your cat’s diet has a lot to do with how well the cat’s digestive system works, so high-fiber cat food may help.

If you are concerned about the health and well-being of your pet, seek veterinary advice for the best course of action.

Obesity

If your pet is strictly an indoor cat, they may become overweight and be vulnerable to obesity because indoor cats don’t get as much exercise as outdoor cats do. Having your cat on a good high-fiber diet will help with weight gain and keep your cat fit and trim like they are meant to be.

Controls Hairballs

Hairballs are a common problem for cats, especially those with long hair. Brushing your cat regularly can remove some of the loose hair your pet swallows, but a high-fiber diet can also help. Several of the brands we discussed are formulated to help with hairballs, but if your cat continues to cough up hairballs frequently, contact your vet for an examination.
