Do you want a pet that is a little bit different? An animal that is more fierce than fluffy? Lizards are reptiles, which means they hatch from eggs and are covered in scales. Reptiles are cold-blooded animals so they cannot control their own body temperature. They rely on outside heat or cold to do this. They live in a variety of habitats, from deserts to rainforests. Some species of lizards can be kept as pets.
