I avoid it all costs. I hit a rabbit the night before Easter. I tried so hard to avoid it but it just happened so quick. Stupid me, being the animal lover that I am pulled over (it was way late and I lived in a small town) and went over to see if it was alive and it was dying. I regret stopping. I cried my eyes out. It didn't help that my mom tried to crack a joke about me hitting the Easter bunny. I felt SO bad.
I once had a cat recently run out. I slammed on the breaks and it ran into my tire. Again, stupid got out of the car to check on it but it took off and I cried and had to pull over and call my mom to calm me down. A few nights later on a midnight snack run I saw the cat, it was alive! I was so happy. Something similar happened to my dog before he passed away from old age. He was just a young guy and got clipped by a tire, it rolled him and skinned his little nose up and he was sore but he lived.
I hope I NEVER hit another animal. I get too emotional.
