Nature's Variety's Instinct Limited Ingredient Diets are available in two varieties for dogs; Lamb Meal and Turkey Meal, and one variety for cats; Turkey Meal. The dog foods come in 4.4 lb. and 25.3 lb. bags, and the cat food comes in a 5.5 lb. bag. The foods feature one protein and one low-allergen starch each, and contain no grains or gluten. The foods are all-natural, with added vitamins and minerals, no artificial colors, flavors or preservatives, and contain essential fatty acids from canola and coconut oils for a healthy skin and coat, the company states. As the owner of a dog that has poultry allergies, one reviewer stated it is great to find high-quality foods with limited ingredients. With lamb meal as the first ingredient (and only meat source), the protein content is relatively high. The food is grain-free and gluten free, and the carbohydrate content is relatively low. The test dog likes the food and it has not caused any stomach upset or other issues.
