Logan, one of the indoor cats, got outside sometime last week. He's been coming to the door, but if someone comes near to open it, he runs.

Meanwhile, one of the outdoor cats has started running in when someone opens the door. He doesn't stay long. He just looks around and then he's ready to go back outside. I think he's just trying to establish that the doorway is not the limit of his allowable territory.

One outdoor cat came up and sniffed my arm hanging down from the chair. Shortly after, another one came up on the other side and started licking my arm. It was hot, and I've been sweating, so this may be their way of telling me I need a bath.
