The health of a cat depends on the content of minerals in her diet. A diet poor in minerals can lead to considerable deficiency symptoms if fed over a longer period of time. There is an increased risk of health problems if the diet is not balanced. Animal products such as muscle fibers, kidney and liver contain too little of some minerals and too much of others. If you feed your cat only commercially prepared cat food you don't have to worry about not giving her enough minerals in her diet.
Among the most important minerals are:
Besides these minerals that the body needs as building blocks, there are others that are necessary in small amounts as trace elements: zinc and iodine for fur formation; copper and iron for sufficient blood formation.
