Multiple home-invasions!

First 2 different cats we've never seen before came in through the open front door at night and took a look around in the house. Resident cats more or less ignored them but they fled when they saw host.

Just now a large bat flew in through the window and circled in the living room, confused from its own echolocation. Took a while to shoo it out through the door. I thought those critters lived in caves and attics? How come they are totally inept of finding their way out through large windows or doors?

It was cool though, I think it was the greater mouse-eared bat. It had really large ears.
