I must say, btw, that I am not an "amateur" mouse remover. I've just never had one spring backwards so unexpectedly... And honestly, old car, could give a s**t about upholstery, but don't madly want to deal with the dog catching it while she's in there. And I've seen them leap, and I've shoo'd squirrels and chipmunks out of the house, and was quite impressed with the athleticism, but leaping out of the top of a window 2" down?
And a spontaneous poll, bet those who are worried a bit about rodents didn't have them as childhood pets. I had both hamsters and gerbils; my kids had mice, rats, guinea pigs. On top of a "normal" number of dogs and cats, at appropriate points. My Siamese cats used to babysit my son's rats while he cleaned their cage.
