High-fiber cat food contains fiber-rich ingredients, such as whole grains, fruits, and vegetables, to support your cat’s digestive system and provide additional nutrients. As cats are carnivores, their diet should consist predominately of high-quality meats and animal fats. Still, certain health conditions could benefit from a high-fiber diet.

Cats living exclusively indoors tend to become less active, sleep more, and groom more. These life factors affect their nutritional needs. The diet of cats in the wild would naturally include fur and bones, which are indigestible and function as fiber in the cat’s digestive system. Without this, you may need fiber in your cat’s diet to support their digestive health.

Dietary fiber is the portion of plant food that the body’s digestive enzymes cannot break down. There are two types of fiber: soluble and insoluble. Soluble fiber dissolves in water—creating a gel—while insoluble fiber remains more or less unchanged as it moves through the digestive tract. Many plants contain soluble and insoluble fiber, supporting gut health.

Is Fiber Good For Cats?

Yes, fiber can be good for cats. Here are the top five ways fiber can benefit your cat:

  1. Constipation: Insoluble fiber adds bulk to your cat’s stool to move it through the digestive system and improve digestion.
  2. Digestion: Soluble fiber attracts water and breaks down into a gel-like consistency. It improves digestion and regulates blood sugar. Some types of insoluble fiber are considered prebiotics, which feed gut bacteria and helps the microbiome thrive.
  3. Hairball Control: Increasing fiber content helps move hair through the digestive tract to reduce the chance of vomiting up hairballs.
  4. Regularity: Fiber can improve regularity and stool consistency. Soluble fiber absorbs water to reduce incidents of diarrhea, while insoluble fiber softens the stool and makes it easier to pass.
  5. Weight Management: High-fiber foods increase the feeling of fullness, which is perfect for a cat on a vet-imposed diet.

Blue Buffalo Tastefuls Indoor Hairball & Weight Control Review

Blue Buffalo Tastefuls Indoor Hairball & Weight Control
  • Chicken & brown rice recipe
  • No corn, wheat, or soy
  • Formulated for weight management and hairball control
  • Free of by-products, artificial flavors, and preservatives
  • Prebiotics and probiotics for digestive support
  • 8% crude fiber

This chicken-flavored, grain-friendly formula contains a mix of soluble and insoluble fiber to keep your cat full while supporting digestion and hairball control. According to Blue Buffalo, this formula was formulated for indoor cats to support weight management. The formula is made without by-product meals, corn, wheat, and soy. It’s free of artificial flavors and preservatives but does contain caramel color. The recipe blends LifeSource Bits—small, dark kibble featuring vitamins, minerals, and antioxidants—along with the standard kibble.

Each bag of Tastefuls Adult Cat Weight & Hairball Control contains the following:

  • Fiber sourced from whole-grain barley, whole-grain brown rice, peas, powdered cellulose, dried tomato pomace, flaxseeds, psyllium seed husks, sweet potato, carrots, blueberries, cranberries, apples, blackberries, spinach, pumpkin, barley grass, and parsley
  • De-boned chicken
  • Extra antioxidants from pomegranate, turmeric, and dried kelp
  • Yucca extract, prebiotics, and probiotics for digestive support

To prevent any adverse effects when transitioning to this high-fiber kibble, Blue Buffalo recommends mixing 25 percent of Tastefuls with your cat’s old food, gradually increasing the proportion over 14 days. Feed your feline this recipe dry, or add to water and mix thoroughly for extra hydration. (Because fiber absorbs water, it is essential that your cat gets plenty of fluids. Not enough water could lead to dehydration, abdominal discomfort, and constipation.)
