This mix is formulated to provide a high protein meal which ensures a good supply of the vitamin, thiamine (B1) and the amino acid Taurine which promote good health in both cats and dogs but are vital to a cat’s well-being. Cats need 5 time more Thiamine that dogs for a healthy metabolism and Veal is a great source for this. Lamb heart, kidneys and liver are one of the best sources of the amino acid Taurine, which unlike dogs, cats are unable to manufacture and must source from protein, so is an essential amino aid to them. Taurine is vital for the healthy functioning of the eyes and heart. Liver is also one of the best sources of Vitamin A which aids a healthy vision, plus bone and muscle growth and reproduction. Cats have a special requirement for Vitamin A as unlike dogs, they cannot get it from plant matter.
