Lizards are becoming a common exotic pet in many parts of the US and around the world. Some are very small and can be housed in cages or aquariums, while others can grow to pretty impressive sizes. A few small lizards that are good for beginners are Gekos and Chamelons. Be careful to make sure the type of lizard you purchase is compatible with the environment in which you plan to house it. For instance, certain Gekos like humidity, while others like it dry - make sure you match this up correctly.

The most common large lizard is the iguana. These lizards can grow as quite long and sometimes become aggressive. They'll need a relatively large aquarium, a light and plenty of food. Make sure you do your research carefully before committing to an iguana.
