Our Kangaroo Formula features a novel, lean animal protein that also happens to be one of the healthiest meats in the world. Rich in nutrients, Kangaroo has twice the amount of Vitamin B12 than any other meat protein. This means twice the fuel for healthy nerve and blood cells, which leads to healthy functions throughout the body. It also has high Omega-3 content for good heart health. Our Kangaroo Formula is always grain free to help reduce food sensitivity and allergies. Zignature® Kangaroo Formula – Learned from Nature, Crafted to Perfection.
