My wife reminded me in one of her comments that just before (potentially) shutting in the squirrel, I had an exchange with my youngest daughter that went something like this.
"Come on honey. Let's go pound on the porch and see if we can scare that squirrel out of the roof."
"I hope he comes running out this time."
"Well, if I close up the hole before he gets out, he'll die in there and stink."
"Yeah. Just like the dinosaurs."
"That's right. He'll go extinct."
