Nature’s Most Complete Food. At Fetch Natural Pet Market, we call goat milk "The Universal Milk" because it is tolerated by almost every mammal. Unlike cow’s milk, goat milk contains smaller fat globules and lower levels of lactose, making it incredibly easy to digest. Our raw goat milk collection, featuring Primal Raw Goat Milk, is loaded with naturally occurring probiotics, electrolytes, and over 200 species of "good" bacteria. It’s the perfect daily supplement to build a resilient immune system and soothe chronic digestive upset.
