We have always had lizards. They are mostly inoffensive and unobtrusive. In the movies they are always used as the models for the monsters, but in real life they are pretty cute and keep to themselves. In the the early morning, they have to warm up before they can move around much and you can find them sitting in the sunlight, sometimes doing "pushups" to get their blood evenly warmed and circulating. Anything that eats bugs is a friend of mine.
