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 plant-based DHA Omega-3 fatty acids to support immunity.
