It is true that cats are obligate carnivores, but carbohydrates perform an important function in the diet and digestive process. They provide a source of energy, and also a source of fiber. The fiber-rich, complex carbohydrates we use as part of our P.B.F. Prebiotic Balanced Fiber ™ offer significant benefit to a cat’s overall health and wellness. Carbohydrates also play an important role regarding texture and shape of the kibble. When the starch in carbohydrates is cooked with other ingredients, they help bind the mixture to produce kibble with a specific texture and shape that is appealing to dogs and cats. The texture and shape are also important to support healthy teeth and gums. Carbohydrates in pet food can come from many sources, such as chickpeas, peas, pea flour.
