Dust Bunnies & Bats in the Belfry?

Lately, I've been feeling inept since I don't raise anything. I use to have a garden, but when I go on my builds they either burn up or the weeds take over, so this year I didn't even try. (forgive the previous sentence, it's not worth the effort to fix it, if I could) I guess I raise grass, because I spend a lot of time mowing it. The other thing I raise really well is dust bunnies. They are multiplying even as you read this. Oh, and I had more apples from my one little tree this fall than I ever had. Also, tonight, I discovered I must be raising birds. I can hear a bird chirping in the ceiling over my head. I went outside in the dark cold with a spot light to see if the screens on the gable vents had come off, but they look intact. Tomorrow I will get the extension ladder and see if there is an opening into the house attic from the garage. I came home one day this week and the garage door was open. Sometimes those darn cats run in as the door goes down. However it got in, I suspect it will have to die there. I sure hope it doesn't stink. I'm not opening up the attic from the inside and having a bird loose in the house. It's very stressful being a homeowner!
