Gerbils are small furry rodents. They're sometimes referred to as desert rats because they're close in heritage to rats, and evolved in arid habitats. Signs of this evolution are visible on the gerbil; for instance, did you know that the fur on its back feet is to protect it from the hot sand? It's true! The little gerbil is completely covered in fur for the necessity of protection against the sun and heat. Gerbils are popular pets because they're quiet yet inquisitive and fun to watch climbing and digging. Any gerbil lover will dig this wall calendar of furry, fun and fabulous gerbils.
