I have a chipmunk in the dining room. Yesterday afternoon I went in there for something and heard a terrified shriek from under the small bookcase between the windows. Oh dear, I thought. We have a guest.
So I left the window up, a chipmunk sized but not cat-sized opening, and closed the door on my way out. He shrieked once more and was still.
This morning I went in to see how things were going and he screamed at me again. The cat came hurrying over, surely intent on comforting his new best friend, but I put him outside the room and closed the door. Cat food, I thought. Little chipmunk-sized kibble. And water. Can't have him dehydrating on me. The kibble leads to the chair placed artfully and invitingly in front of the table that leads to the outside.
This is his last chance to figure it out. By tomorrow morning if he's still here I'm letting the cat in. There is a limit, and I so do not want to be sharing quarters with an overfed chipmunk and all his friends...
