Inspired by the diet of the lynx, BLUE Wilderness is a high protein food that will provide your cat with a higher concentration of the protein she loves. BLUE Wilderness natural cat food is also a sensible alternative to less convenient raw diets, which often require additional supplementation to be nutritionally complete. This is an important difference between BLUE Wilderness and many other wet cat foods. Some brands use wheat as a thickening agent in their food, but wheat has been known to cause allergies in some cats.
