Diet

What is a camel's diet?

 The Camel may have to live on dried leaves, seeds, and whatever desert plants it can find. A camel can eat a thorny twig without hurting its mouth. The lining of the mouth is so tough that the sharp thorns cannot push through the skin. If food is very scarce, a camel will eat anything--bones, fish, meat, leather, and even its owner's tent.
