Okay, based on some comments, I'm also going to ask: have you ever hit a squirrel?
It's kind of unavoidable when you live here... Never swerve for anything smaller than a dog.
It was only once & it was when I was first driving.
Maybe a kangaroo rat.
No when I was growing up I had a pet squirrel that I would feed.
Okay... i've hit a cat, bird and ran over a rattlesnake sunning on the road. Oh......and millions of friggen bugs. The only ones that didn't sadden me was the bugs.
