Be sure to add your cat’s daily supplements to each meal in the quantities recommended for each on the packages. A good quality vitamin/mineral supplement. A bone meal supplement. This can be either nutritional grade bone meal, finely crushed eggshells or a calcium lactate supplement. 250 to 500 mg. of taurine per day. Many owners will also provide oat grass or wheat grass plants for their cats to chew on. (Check to make sure that the grass you select is not toxic to cats. Several are.) Preparation and cooking times are approximate.
