I’m going to give you a link to follow. It is all about dog food. Everything they talk about is the same for cats. At the end of the article it has a list of great pet foods. When you feed your cats one of these foods, you will feeding them the best nutrition available.
Good food equals better health, which equals less doctor visits and a happier healthier cat. If you change your cat’s food, do it gradually. Add some kibble from the new food to the old and increase the amount every day until it is all new kibble.
Yes, you can apply this to your self as well! :-)
