Enzymes found in fresh, raw foods not only play an important role in digestion but support your pet's overall well-being. Enzymes allow your animal's body to absorb essential nutrients he wouldn't otherwise benefit from. And because his body is able to utilize those nutrients, his immune system is stronger. All the fruits, veggies, grains and meat in Sojos mixes are raw, meaning those crucial enzymes are intact and your pet will benefit.
