The girl let me out into the living room this afternoon for a little bit, and I was surprised to see the two other kitties there. They didn't come up to greet me, but stayed on their chairs and watched. The girl had some treats, so I decided it was best to follow her in the hopes of getting a few.
The red tabby left the room after a few minutes, but the greyish one stayed to watch. I didn't get to be out long, but it was nice to lie in the sun for awhile.
