My boyfriend found a lizard in a swimming pool skimmer basket the day before yesterday. we live in las vegas, and the lizard is quite large (4 inch body, 7 inch tail at least) what do we have-we would like to build this lizard a happy habitat. this guy has a almost white underside, banded on top of tail, fringed long hind toes, irregular pattern on top of body. any help is greatly appreciated-
