This Nick (there are several of them) is almost a pet. It spends a lot of time on our front porch for some reason. It seems it's chewing on the floor boards - principally in the spot where Swee'pea pees when it's raining and she doesn't want to get wet. Not sure if that makes it taste good, or if it's just keeping its teeth in shape and using the floor as a grindstone. In any case, it made me laugh out loud when I saw it sitting on the step looking at its favorite spot and then at me.
