Feline Health is a combination of organic grains, vegetables and herbs. When used as a pre-mix and combined with protein and fish oil Feline Health provides a total all natural diet for cats. Although switching cats to an all natural diet can sometimes be a challenge in most cases, with patience and persistence it is possible. In the long run eating this way keeps cats healthy, increases longevity and strengthens the immune system. Even finicky cats ( and aren’t they all) can be switched slowly by adding small amounts of Dr. Harvey’s Feline Health to the foods they are already eating. Over a period of time, cats should be weaned off commercial food and more of the all natural proteins and grains can be added. After a time, cats truly love this way of eating and their health picture will improve along with a shinier and healthier coat and skin, better gums and teeth and less tendency for arthritis and other degenerative diseases
