Fiber is a key component of your pet's diet, but not all fiber sources are equally good for your pet. Some fiber can actually contribute to gastrointestinal problems. Higgins Vita Garden is made with our proprietary Fiber-Biotic pellets that are scientifically formulated with a multi-fiber, nutritionally balanced approach for your pet's optimal health. Fiber-Biotic pellets are gluten free and blend multiple, natural fiber sources beneficial to omnivores to support overall health, digestion and firmer stools. Vita Garden contains Hemicellulose Extract, a natural soluble fiber that is also a prebiotic source to support nutrient absorption and the immune system. Vita Garden also has protected probiotics and DHA Omega-3 fatty acids to support immunity.
