Just had a bat in the house. Coming out of hibernation , I guess. I left the kitchen door open and he flew past it 3x. I did not want to kill it, but had to smack it with a cardboard box. I threw it out side and it was gone the next day. It may have only been stunned. Something got it I guess. They look pretty fragile. Had flying squirrels in the attic once, that is about all for critters.
