My little Lizard,,,,

I came home from work tonight,,,,,and I found this little lizard!

It is sooooo cold outside!

He was laying there on the concrete, he was limp, he was black.

My daughter told me to leave him alone, that he was dead!

I picked him up and there was a little movement.

Here is what he looked like.......

So I brought him into the house. I couldnt stand the thought of leaving him out there to freeze to death! So he is nice and warm now! His color is coming back now!! 

He is looking good!! But now I dont know what I am going to do with him! I read about them and they eat live bugs or earthworms.
