I saw someone's house cat get hit right in front of me. I saw it coming racing across a yard, I waived to warn people, the other lane stopped, but this idiot came flying by, hit it and kept going like nothing happened. The cat was half alive and scrambled into thick brush/woods area with it's front legs. I went to house to notify them, but they had no idea. I went to look for the cat, but couldn't see it in the tall brush area. I am sure it died and I felt terrible.
Another one is a few college teammates were on a run and this big dog came running across the road, an old lady came nailed the dog and it went flying by the guys heads while they were running. She almost hit them too (one was clipped by her door mirror). She kept going, dog was dead and they were pretty shaken up by the close call of getting hit themselves.
