It is always so upsetting to see things like this. I have seen a dog get hit, and a cat get hit, and box turtles get hit when I lived in Missouri. Every time it upset me deeply. I used to stop and move the turtles too whenever I could.

The only thing I know of that I have hit myself was some sort of lizard when I was on my way to work in Branson, MO. I didn't see it till it was totally too late, and the road was hilly and dangerous with no real shoulders (Ozark Mtn roads). I saw it flopping around in my rearview and felt sick and distressed the rest of the day. I have never forgotten it either.

I'm glad you were able to move the body. I hate seeing them get hit over and over and like you said, maybe hitting other animals that are drawn to it as a meal.
