Unfortunately, like CatDog, I have seen far too many in Florida. The area I live in now is a bit lower on the mortality, but when I lived farther south it was even more common. Armadillos, raccoons, opossums mostly. Plus snakes, birds, bobcats, coyotes, etc... I remember when it was still somewhat common for people to hit Florida panthers. I've already seen a Burmese python hit on a road in homestead.
I have to euthanize a few animals myself as well, and that is never easy. Everything comes to "that time" eventually. That is always sad.
