Wellness CORE is based on the nutritional philosophy that pets, based on their primal ancestry, thrive on a diet mainly comprised of meat. Each kibble is packed with a high concentration of quality animal protein, without fillers or grains, along with a proprietary blend of botanicals and nutritional supplements including probiotics.Unlike many grain-free diets, Wellness ensures the overall nutrition equation remains appropriate for everyday feeding. Higher protein can also mean higher fat, minerals and calories. By thoughtfully selecting specialized ingredients and managing nutritional ratios, Wellness CORE delivers protein-focused nutrition – with balance, not excess.Wellenss CORE Indoor is fish-free & omega-rich for healthy skin & coat. It helps to reduce hairballs & maintain a healthy weight and promotes lean muscle mass. The formula is also grain-free and gluten-free.
