The Best High Fiber Cat Foods and Why Does Your Cat Need It?

Have you ever asked yourself: how can I keep my cat healthy and happy? Feeding your feline friend with high fiber cat foods is a massive step in the right direction. This diet helps to ensure their digestive health and regularity.

That’s why we are going to review the best commercial high fiber cat foods and why you should buy them.


Everything You Need to Know About High Fiber Cat Foods

Does Your Pet Need a High Fiber Cat Food?

Just like us, our feline friends need to eat balanced diets to stay fit and healthy. Suitable nourishment includes eating enough fiber. However, many pet foods are severely lacking in this respect. That’s why many brands today produce food that is uncommonly high in fiber.

This food ups the fiber content in your cat’s diet through a variety of ingredients. They are mostly vegetables such as sweet potato, pumpkin or lentils.

Fiber should make up 0.55% to 10% of your cat’s daily meals. The products on this list all contain more than 3% but not more than 10%. So the total fiber intake for each cat of any age will vary based on how much they eat. For example, if your cat eats 5 oz of kibble a day, up to 0.5 oz can be fiber. Remember that a fiber content above 10% can have adverse effects.

Before buying a product, you can check for this percentage under its nutritional facts.

A lack of fiber can have adverse effects on your cat’s digestion as well as their weight.

Here are some signs that your cat might need more fiber in their diet:

  • Your cat regularly struggles with hairballs.
  • Your cat is constipated. Signs of constipation are, your cat isn’t eliminating feces every day and when they do it is hard, dark colored and difficult to pass.
  • He or she is overweight or obese, and you are struggling to manage their weight. Obesity has increasingly become a problem among domestic cats. It can be especially difficult to regulate a mostly indoor cats weight.
  • They struggle with other digestive problems like diarrhea and vomiting.

Switching your cat to a diet that is higher in fiber can help to manage these problems.

Benefits of High Fiber Cat Food

You will probably be pleasantly surprised by the difference that a high fiber diet will make to your cat’s wellbeing.

The following are some advantages of feeding your cat a high fiber diet:

  • A 2012 scientific study has shown that this type of food can help your cat to lose weight, and can help your pet to feel fuller for longer. More fiber will be particularly beneficial for indoor cats that don’t get as much exercise.
  • High fiber cat food could help you to treat your pet for constipation and hairballs.
  • This diet can lead to an overall improvement in your pet’s gastrointestinal health and will help to prevent them from developing digestive issues.
  • Increasing your cat’s fiber intake can even help to regulate their blood sugar and can, therefore, help for diabetes.

Below is a helpful youtube video that gives you more advice on choosing the right food for your cat.

This diet is a readily available way to address your pet’s health issues. All of the high fiber cat foods that I am going to review are over the counter. However, if your cat has more severe problems, you can ask your vet about possible prescription foods instead.

Even though fiber is a necessary part of a cat's diet, don’t overdo it. Stick to the feeding and serving guidelines recommended by your vet or by the specific brand.

What Do You Want in High Fiber Cat Food?

1. Ingredients

Before you feed your pet anything, it’s worthwhile to go through its list of ingredients. Cat food with high fiber contents often have recipes that contain more natural components. It’s always a great bonus if it also uses organic ingredients.

Other possible supplements could be probiotics and prebiotics.

If your cat regularly struggles with diarrhea or other gastrointestinal issues you might want to learn more about what they are eating. Your feline friend could be allergic to specific ingredients such as chicken. Many cats are also sensitive to grains so you should consider trying a grain free alternative.

2. Flavor

Healthy doesn’t mean that your pet’s food can’t be delicious. You will be able to find these foods in a variety of flavor options like chicken, salmon or duck. Each cat will have their taste preference so you might need to test a few choices before they are satisfied.

3. Type of Food

If you want to change your cat’s diet, it’s often easier to give them a type of food you usually feed them. If your pet regularly eats canned food, stick to wet alternatives and vice versa.

There are usually more dry high fiber options like kibble available than wet ones.

Nowadays, you can also buy biscuits and treats that are high in fiber.

4. Characteristics of Your Cat

When you buy any food for your cat, you should keep your cat’s specific attributes in mind. Cats of different ages have different nutritional requirements. So to keep them happy, your kitten and senior cat should eat food that is made with them in mind.

You might also find food that it’s meant for specific feline breeds.

5. Safety

Before making a purchase, you need to check whether the food has been approved and tested by the appropriate governmental bodies. The food and its various ingredients should be of a high-quality.

Before you look at the pros and cons of each product, keep in mind that high fiber options will often be labeled as digestive diets, helping with hairballs or being for indoor cats.
