My veterinarian says cats shouldn eat carbohydrates and should be on grain-free foods. Why does Halo have grains in their cat food?
Low carbohydrate foods are best suited to the natural biology of cats as carnivores. Cats reach optimal health levels and can avoid many food-related problems (such as obesity, diabetes, etc) by eating high-protein, low-carbohydrate foods. Protein, not carbohydrates, should comprise the majority of every cat’s diet, however, many cats appear to benefit from a small to moderate amount of carbohydrates in their diet. It is important to remember biology and evolution when it comes to cat nutrition. When cats hunted for their food, they were exposed to whole grains and carbohydrates within the digestive system of their prey. The domesticated indoor cat appears to benefit from the digestive health that complex carbohydrates (in the form of fiber-rich vegetables or whole grains) provide. Carbohydrates as simple sugars should always be avoided. Only these complex carbohydrates (that are not broken down to sugar) should be used in cat foods to impart digestive benefits.
