I'm not kidding when I tell you this. I think that Daisy was trying to teach Wren how to use the doggie door. No joke. He was sitting next to it. She would walk through it to go outside and then turn to come back in and sniff or lick him. He would flick the door a little and then she would repeat her demonstration. This went on five or six times. I went to get the camera to try to capture it, and even with my sneakiness they stopped when they heard the camera turn on. Dangit.
