Wellness Pet Nutrition is a reputed brand of pet food made using high-quality natural ingredients. The company primarily offers two lines of cat food - CORE and Complete Health. While the CORE line is known for high-protein, grain-free cat food, Complete Health offers a selection of grain-free and grain-inclusive options. Another key difference is that Wellness Complete Health cat foods target specific life stages and lifestyles. For instance, the range includes options for weight management in cats, as well as canned food for indoor cats. Both Wellness CORE and Complete Health cat foods offer a wholesome diet for your pet, and are free of wheat, corn, and soy. Also, they’re made using natural ingredients sourced from plants, animals, and minerals. These foods are free of artificial flavors, colors, and preservatives.
