One of the most commonly overlooked nutrients in a cat’s diet is fiber. This is because cats are obligate carnivores and don’t need fiber from plant sources in the wild and therefore, we don’t see why our domestic cats would require a high fiber diet. 

Wild cats eat entire animals, including bones and teeth which serve as sources of fiber and encourage healthy digestion. 

Domestic cats typically eat wet and dry cat food, which doesn’t contain these kinds of ingredients. Adding a form of plant fiber keeps their digestive tract functioning at its best!

Top Picks For High Fiber Cat Food

What Is High Fiber Cat Food?

High-fiber cat food is fortified with ingredients that encourage healthy digestion. This can either aid in constipation or help to reduce diarrhea, depending on the ingredients used. Choosing the right cat food will depend on your cat’s lifestyle and dietary needs. 

Domestic cats require additional fiber compared to their wild ancestors. They sleep more, exercise less, and groom themselves and each other. This slows down the digestion process and creates problems like bloating, gas, constipation, hairballs, or diarrhea.

    Types Of High Fiber Cat Food

    Before investing in new cat food, you need to be aware of the different kinds of fiber to feed your cat for optimal health. If you aren’t clear on exactly which type of food is suitable for your cat, the underlying issue they’re having may be exacerbated by the new food. 

    Once you’re clear on exactly which fiber is fitting for your cat, you’ll see considerable improvements in their health. 

    Soluble Fiber

    This is the kind of fiber you’ll want to add to your cat’s diet if they’re experiencing any constipation. Soluble fiber works by drawing water out of the bloodstream to digest the food once it reaches the large intestine. This aids the colon in fermenting the food, and since there’s an increased amount of water in the digestion process, it loosens the stool. 

    Keep in mind this kind of food will also move through the body much faster, so after you feed soluble fiber to your cat, you should expect to see them using the bathroom much quicker than they have with foods with low insoluble fiber. This is natural and means the food is working; however, if you find that your cat’s stool is becoming too liquid and turning into diarrhea, you’ll want to cut back on soluble fiber intake. 

    Insoluble Fiber

    Insoluble fiber will help your cat if they have diarrhea. The primary sources of insoluble fiber in cat food are peanut hulls or cellulose. The purpose is to add mass to the food. Since it’s bulkier, it’s also slower to move through the body, slowing down the frequency at which your cat feels they need to go to the bathroom.

    The bulkiness of the food will also do a good job of binding their intestinal matter more tightly, firming stool. This is the reason why you should never feed insoluble fiber to cats that suffer from constipation. 

    Fermentable Fiber

    Fermentable fiber foods are a combination of soluble and insoluble fiber. These foods are optimal for cats that aren’t currently experiencing any issues with their digestion, as this will maintain their natural bathroom routine. 

    This type of fiber in food will be the most ideal for most cats as it doesn’t alter the consistency or urgency of their defecation and instead will simply encourage proper digestion. By combining the two sources of fiber, you may find that your cat has less bloat and overall gas since their digestive tract will stay cleaner. 

    Common ingredients that serve as fermentable fiber include:

    • Peas
    • Oat Bran
    • Pumpkin
    • Beet Pulp

    Should You Buy High Fiber Cat Food? 

    While high fiber foods are ideal for cats that need an extra push of digestive power, it isn’t necessary for all cats. Therefore, just because a high fiber diet can be helpful for some cats doesn’t mean you should feel that you have to supply it to yours. 

    Always take a look first at your cat’s overall health to determine if they could benefit from additional fiber, or if it’s an unnecessary dietary change, 

    Benefits Of High Fiber Cat Food

    The number one benefit to dietary fiber is the ease in digestion that it brings. For animals that struggle with poor digestion resulting in uncomfortable constipation or urgent diarrhea, fiber may be the answer!

    If your cat is prone to hairballs, introducing more fiber into the diet can minimize their gagging and vomiting as well. By digesting hairballs more effectively, you won’t see your cat lose interest in food due to the lethargy that comes with hairballs being lodged in the digestive tract. 

    For breeds more prone to obesity, high fiber diets encourage complete digestion and absorption of nutrients, making it harder to put on extra weight. This can keep your cat in better shape and improve their overall energy levels.

    Problems With High Fiber Cat Food

    High-quality protein can be sacrificed when adding more fiber into a formula which is a major downfall to a diet since protein is the most important nutrient for felines. However, since fiber sources are plant-based, they’re generally cheaper than meat-based proteins, which causes cat food companies to cut corners. 

    If you’re turning to a high-fiber diet as a potential solution to digestive problems in your cat, bear in mind that this can make it worse. If the underlying problem is allergies, the foods used to increase fiber will greatly worsen allergies. 

    By failing to properly research which high-fiber food is best, it’s also possible to give the wrong kind of fiber to your cat. This can also make their problems worse and put them in greater discomfort.

    Buying Guide

    When you intend to change the diet of your cat, you should first and foremost consult your veterinarian and animal nutritionist. If you want to make sure your cat’s needs are being communicated clearly to a specialist, you should pay attention to its behavior, as this will determine what kind of food might be best for your feline.

    Your Cat’s Health

    By taking a holistic look at your cat’s health, you’ll best be able to determine if a high fiber diet is best and what source of fiber they’re most in need of. 

    The ideal way to go about this is to consult with your veterinarian. Ensure that your cat doesn’t have any preexisting conditions making it dangerous to consumer higher fiber diets.

    Grooming Habits

    All cats groom themselves; however, some cats lick themselves a lot more frequently than others. 

    If your cat is constantly grooming or has long hair, they may need a boost in their digestive tract to help them break down the hair they’re accumulating in their gut. 

    Exercise Habits

    If your cat isn’t a fan of exercise, you’ll want to ensure they’re getting a healthy dose of fiber in their food to keep their digestive systems moving. 

    If your cat is very active, they likely won’t need as much fiber in their diet as their organs will have an easier time waking up and moving food through.

    Consider your cat’s energy levels to determine better if they need fiber and how much is ideal for their diet.

    Bathroom Habits

    While many pet owners avoid taking a deep look at their pet’s urine or feces, it’s important to take note of any changes in their bathroom habits to catch any potential changes in health. 

    If you notice that your cat has diarrhea, you’ll want to consider which type of fiber is best for reducing this symptom. 

    Alternatively, if your cat is experiencing constipation, you’ll want to give them different food. Only by noticing how your cat’s feces are changing can you properly evaluate what kind of high fiber food they need. 

    Fiber Source 

    Since the dietary fiber source differs depending on the food you decide on, it’s important to be aware of the pros and cons of each fiber source. 

    Keep in mind that it’s natural for your cat’s fiber needs to change throughout its life. While one fiber source may be ideal at a younger age, another may need to be introduced as health requirements vary. 

    Therefore, rather than considering one fiber source as “better” or “worse” than another, simply stay aware of what each one can offer your cat so that you’re able to switch to a different food based on what you see from your cat. 

    Other Ingredients

    Grains aren’t a necessary part of a healthy diet and can be problematic for many cats that struggle with allergies or weight gain. 

    Many of the high fiber diet foods could contain more grains than you would expect. Since many grains, like corn and wheat, are prevalent allergens, these diets may cause more health issues. 

    In addition, these kinds of additives add weight to your cat without adding much nutritional benefit. 

    Before switching to any new diet, consult with your veterinarian to ensure it has the healthiest balance of ingredients possible. 

    Always allergy test your cat to stay up to date on their food intolerances. Since allergies can develop and change throughout your cat’s life, be sure to test them when they are kittens and adults. 

    How Does Fiber Help Your Cat?

    The body of your cat is designed to run as efficiently as possible; therefore, by improving your cat’s health they will also be able to enjoy better coat health, dental health, and a stronger immune system. 

    Healthy Stool

    If your cat is consuming a healthy diet with fiber, they will have a more regular bathroom schedule with firm and healthy feces. This is vital in reducing stress on the body and increasing nutrient absorption. 

    This will make a considerable difference in cats that are prone to digestive health problems.

    Reduced Bloat And Gas

    With healthier stool also comes healthier digestion. Once your cat’s body is able to digest without inflammation and backup, they’ll experience much less bloat and gas. 

    This can make them considerably more comfortable and make your living space more livable for the humans around!

    You can continue cutting down on bloat and gas by avoiding grains in the diet and by checking your cat for allergies!

    Maintains Energy 

    One of the biggest energy sinks is unhealthy digestion. If your cat’s body is putting a ton of energy into digesting each meal, they won’t have any energy to play or engage with you. 

    When more fiber is introduced to bring about easier digestion, the energy input will be much lower, which will lead to a more playful cat!

    Conclusion On High Fiber Cat Food

    While high fiber food has its benefits for cats that need extra immune or digestive support, it’s by no means necessary for all cats. 

    If you don’t see any problems in the consistency or frequency of your cat’s defecation, you may be better off sticking to your usual cat food.
