Chicken is also rich in L-carnitine, an amino acid that develops a healthy metabolism and further supports muscle development.

Added potatoes ensure high levels of antioxidants such as vitamin C, phenols, and carotenoids which prevent damage of cells and prevent severe diseases like cancer. [2]

Whole peas are a fiber-rich ingredient that develops healthy bacteria in the digestive system and aid in digestion processes. The inclusion of this whole vegetable provides a natural balance of fiber while restricting ash content in the recipe.

The exclusion of whole grains, corn, wheat, soy, and gluten makes this recipe a popular choice among cat owners. The high protein ingredients in the formula are also a bonus because it reflects a cat’s ancestral diet.

Many owners noticed improvements in their cat’s digestion and constipation when feeding this diet to them. Other feedback from cat owners informed of a lack of odor too. However, this formula may not be suitable for cats with chicken sensitivities.

Glucosamine and chondroitin promote healthy cartilage tissue in cats, which aids stressed joints and prevents joint-related health conditions such as osteoarthritis. [3]

Added turkey meal gives the recipe a rich source of taurine and contributes to the overall protein content. Taurine is an essential amino acid that promotes vision and digestion for cats and prevents severe heart disease like Dilated Cardiomyopathy.

The 17% crude fat content in this formula also contains essential omega-3 and omega-6 fatty acids, promoting healthy skin and coat.

Added whole ingredients peas and sweet potatoes promote healthy gut bacteria that aid in digestion. Likewise, this recipe utilizes yucca schidigera to reduce the aroma in your cat’s feces and aids in the digestion of the nutrients. [5]

Many indoor cat formulas will be specifically formulated to prevent obesity, constipation, and hairballs. This high fiber cat food boasts an incredible amount of meat-based protein sources, restricting excessive carbohydrates and calories.

It is worth noting that the high moisture content in this recipe lowers the crude percentages in this formula. 

The unique use of chicken liver replicates a cat’s ancestral diet, rich in iron and essential amino acids. In combination with the help of whole chicken and chicken meal, these meat-based protein sources largely contribute to the 11% crude protein.

The 11% crude protein content is based on the guaranteed analysis of the formula. In contrast, this 11% converts into 50% crude protein based on a dry matter basis.

The recipe also features a carefully crafted mix of antioxidant-rich ingredients like cranberries, vitamins, and omega fatty acids like EPA and DHA to promote healthy digestion and metabolism.

The unique air-drying process Zeal uses reduced volume while preserving the diet’s nutritional content and enhancing the flavor.

Salmon also provides adequate levels of vitamin B6, which helps with the digestion of protein. In addition, this ingredient offers moderate levels of vitamin B12, which aids in the metabolism of fats and carbohydrates. [9]

High Fiber Cat Food Buyer’s Guide 

You need to consider various factors before switching your cat onto a high fiber cat food.

Although dietary fiber is not an essential part of a cat’s diet, some fiber can aid several health conditions. However, it is always best to consult your veterinarian before making any permanent changes to your cat’s diet. 

The Different Types of Fiber 

Fiber can be found in plants as well as animals. Because cats are obligate carnivores, they should consume nutrients such as fiber from animal-based sources.

There are two main types of fiber: soluble and insoluble fiber. [18

Soluble fiber helps break down and soften the stool in the digestive tract, slowing down the metabolic process. It supports the work of the colon and is beneficial for cats with diarrhea. 

It’s naturally found in beans and legumesoats, and several different kinds of fruits and veggies. However, you may also see pectin or gum in cat food which are soluble fiber ingredients.

Insoluble fiber, on the other hand, doesn’t break down in the digestive tract. Instead, it pushes the blocked stool along with it, aiding digestion. Insoluble fiber is found in kidney beanswheatbran, several vegetables, and fruits, to name a few. 

The fiber that is in your cat’s food will depend on their exact dietary needs. If your cat suffers from chronic constipation, insoluble fibers will feature heavily in the food. 

However, a cat that has excessive diarrhea needs soluble fiber to help them complete digestion. 

Why Do Some Cats Need A High Fiber Diet?

Fiber is essential for digestion precisely because it is more difficult to digest. It cleans out the digestive tract as it goes through. 

Cats are obligate carnivores meaning they don’t need extra fiber because they have evolved to eat only meat. Their gastrointestinal tracts are shorter and digest meat quickly. 

Healthy cats won’t benefit from a high fiber diet. Still, cats with diabetes, bowel diseases, or colon cancer need more fiber. Cats with these issues need special care and treatment, and that includes their diet. 

High-fiber cat food regulates a cat’s body when its digestive system isn’t working correctly. Usually, the signs of this are either excessive constipation, diarrhea, or a combination of both. 

Here are some conditions that benefit from a high fiber diet:

Hairballs

As cats self groom, they pull excess hair by the tiny hooks on their tongue and eventually get swallowed. While some of these will pass through the gastrointestinal tract, others will end up accumulating and forming a hairball.

Many high fiber formulas will primarily contain additional vitamins, minerals, and amino fatty acids that will help develop healthy skin and coats. As a result, this will reduce shedding and the volume of excess hairs ingested by your cat.

Some dietary fibers, mainly insoluble fiber, can help with hairballs because it is less easily digested. These fibers will push the accumulated hair through the intestine and eventually come out in the feces. 

Obesity

According to our veterinarian writer, Dr. Joanna Woodnutt MRCVS, 52% of veterinarians are concerned with obesity. Over 80% say there will be more overweight pets than healthy in the next five years. 

In fact, the Association for Pet Obesity Prevention (APOP) estimates that over half of domestic cats are considered overweight or obese. [19]

Soluble fiber promotes healthy bacteria in your cat’s GI tract and helps prevent weight gain by reducing their appetite. 

These dietary fibers form a gel-like substance in your cat’s gut which slows the emptying of their stomach. As a result, this increases the absorption and processing times for digestion, giving the feeling of ‘being full’ for longer. [20]

Diabetes

In combination with the fact that dietary fiber helps cats lose weight, these fibers can help with conditions such as diabetes.

Soluble fiber helps manage glucose during the digestive process. Small amounts of fiber pass through the GI tract, which means that it is unlikely to cause significant spikes in blood sugar levels. 

Notably, dietary fiber has a lower glycemic index (GI) than other nutrients meaning it’s a suitable food source for cats with diabetes. [21]

Constipation and Diarrhea

Constipation typically occurs when food is passing slowly through the intestines, or it doesn’t contain high traces of moisture. As a result, the feces hardens, and it is causes blockages.

Primarily, insoluble fiber helps accelerate the transit of ingredients in the digestive tract, therefore preventing constipation. However, insoluble fiber balances the pH (moisture) in the gastrointestinal tract and ultimately softens the feces. 

Soluble fiber aids diarrhea by slowing down the digestive process and allowing more moisture to be extracted from the food; this allows the feces to become firmer. [22]

Problems With High Fiber Cat Food 

If your cat doesn’t have gastrointestinal-related health issues, high-fiber cat food can be detrimental to their overall health or development. 

Mainly, this is because cats have short digestive systems designed primarily to digest meat. A healthy cat doesn’t require additional fiber in their diet. [23]

You might have seen high-fiber cat food as an option for cats with obesity. Although obesity is a rising cause of unhealthiness in domesticated cats, higher fiber levels aren’t always the best way to combat obesity or weight-related conditions. 

Fiber cleans out the digestive tract but also strips the body of proteins. Without the proper amount of protein, an overweight cat will lose muscle mass and gain more weight. [24]

While extra fiber might help some overweight cats lose weight by making them feel full longer, it can be detrimental to others.  

This is why we always recommend you consult your veterinarian before making permanent changes to your cat’s diet.

In the wild, cats would typically get intestinal fiber from undigested fur, cartilage, tendon, bone, and ligaments of their prey. [25]

What to Look For When Choosing High Fiber Cat Food 

If you’ve decided that your cat would benefit from high-fiber cat food, you first need to talk to your veterinarian about this potential diet change. 

Make sure to choose a safe, high fiber cat food by first considering some of these factors.

High-Quality Fiber Source

The kind of fiber in the food depends on the health needs of your cat. Check the label for the ingredients to see which kind of fiber it is and match that to the type of issues your cat is having. 

Most high fiber cat foods are a mix of fibers to increase overall digestive health without going too far either way. However, some are specifically made for different issues. 

Some good-quality fiber ingredients are peas, flaxseed, potatoes, oats, apples, carrots, beet, or broccoli.  

While unprocessed and unpreserved food isn’t vital to everyone, the more natural a cat food brand is, the more likely it is to have natural sources of fiber instead of additives.

Balanced Nutrition 

No matter what kind of cat food you buy, it should still provide comprehensive nutrition to support their overall health. A healthy balanced ratio of vitamins, minerals, and amino acids is essential for cats with health conditions that need a high fiber diet.

It is best to find a recipe that uses a meat-based protein source because a cat’s digestive system is primed to consume and digest nutrients from meat.

Adequate Protein and Fiber Content 

Every cat needs moderate amounts of protein content in their diet, even if they are struggling from some of the health conditions we have previously discussed.

Typically, cats need around 30% protein content in their daily diet to sustain muscle mass, provide support for their nervous system, immune system, and promote their overall well-being.

For indoor cats, they require a minimum protein content of 26%.

However, for cats that require high fiber cat food, look for a formula that contains no more than 10% crude fiber. Too much fiber can cause severe health complications for your cat.

If you have any immediate concerns or queries, it’s best to consult your veterinarian.

Final Thoughts 

Cats need small amounts of dietary fiber to support their digestive system. However, cats who suffer from diabetes, obesity, diarrhea, or constipation may benefit from a high fiber diet.

Soluble fiber helps break down and soften the stool in the digestive tract, slowing down the metabolic process. It is particularly effective against diarrhea.

Insoluble fiber doesn’t break down in the digestive tract. Instead, it pushes the blocked stool along with it, which is effective against constipation. It allows the feces to obtain more moisture.

Overall, I found Solid Gold Indigo Moon with Chicken Dry Cat Food to be the best high fiber cat food. This provided the perfect balance of vitamins, minerals, and amino acids while bolstering dietary fibers.

Nutrient-dense cat food with a high fiber content from whole ingredients can help manage health issues for your furry friend. Consult your veterinarian today to discuss ways to support your cat’s health conditions with a high fiber diet.
