Reptiles make ideal pets because they can take up a relatively small amount of space and their care is not particularly time consuming or expensive. They are not very noisy or messy, and they don't have to be fed everyday. Reptiles are as different in their personalities and nature as people are. They can be very intelligent and have the ability to learn. For example if a lizard escapes it will often return for its food, and if recaptured it will remember how it escaped and do it again. Lizards can also get used to a routine. You may find that after keeping your pet for a while and maintaining a regular feeding schedule, it can become very excited when you come to feed it. Lizards demonstrate their awareness with excitement.
