==Dietary Sources==

Copper is found in reasonable amounts in some cereal sources such as soya flour and wheat germ meal. The best animal source is liver, especially beef or lambs’ liver. There are moderate amounts in some meat meals. However, to ensure adequate dietary contents, manufactured dog and cat foods are usually supplemented with inorganic copper salts such as cupric sulphate, cupric carbonate and cupric chloride. Copper chelates of amino acids such as lysine are also good sources of bioavailable copper. However, cupric oxide is not suitable as a source of dietary copper for dogs and cats. In one study where adult cats were fed a diet containing cupric oxide as the supplement they showed clear signs of copper inadequacy, even though the dietary copper content was identical to an adequate diet where the copper was supplied by cupric sulphate<ref name="Fascetti"/>.
