I am thinking about getting a lizard, but I don't know if they make good pets.
Lizards are a widespread group of squamate reptiles, with over 6,000 species, 
What species of lizards are good as pets?
A pet or companion animal is an animal kept primarily for a person's company, protection, or entertainment rather than as a working animal, 
That's what I'm thinking with a lizard, I don't think they could do much work for me.  Should I get a Chameleon?
Lizards range in size from chameleons and geckos a few centimeters long to the 3 meter long 
Chameleons get to be 3 meters long?!?!?!?!?!  That's a new one on me.  I would hate to see a 9 foot Chameleon blending in and sneaking up on me.  Scary!
Most lizards are quadrupedal, running with a strong side-to-side
