It was one of the common sagebrush lizards that we call "George." We'd rather not have lizards in the house, but they don't bother me as much as mice. (Lizards do not eat books, for example.) However, before I could do anything to catch him, he skittered away back behind some shelves. I warned Lisa about George and left it at that.
This morning, Lisa was startled to find George the Lizard in the kitchen downstairs, but once again he skittered away before we could do anything about it. Later in the morning, I heard scratching sounds from a paper bag full of dry trash sitting in the kitchen. George had somehow got into the bag and was struggling to get out. I closed off the top of the bag and carried it outside, much to George's distress as he ran about trying to escape.
I told Lisa what had happened, and she came out with me to the vacant lot next door, where I put the bag on its side and opened it up. Out popped George, who then sat there for a while. We left him be and I went back to work.
We actually like having these lizards about, because they eat bugs. We just would rather not have them inside the house if possible.
