Not long ago I hit a raccoon, a very big raccoon. A friend and I were out shopping one evening and had her three kids in the van with us. It ran out in front of us but I couldn't swerve, there weren't any cars in front of me but there was a lot behind. The worse part was the really loud thunk when it hit the bottom of the van.

Luckily the 5yo didn't see what we hit and when he asked what the noise was we said we ran over a rock, a big rock. The oldest child played along but the middle one, Mr. Johnny Come Lately, 5 min. down the road says, "Was that a raccoon?".
I don't really get too upset about hitting wild animals, there is no control in that but a pet would really bother me. I did hit a dog once, but didn't kill it, thankfully. This was out near my Aunts house in the boondocks of MO and the dog was not leashed.
I have to say pets not being leashed near a road and unrestrained in a car really bothers me. I may get flamed but it really peeves me when I see someone driving down the road with their dog in their lap. You wouldn't do this with your child, why would you do it with your pet. It just gives me the willey's to think about what would happen to that dog if the driver got in an accident. Now I do not have a dog, I am allergic

and would like to have one, a little one I can carry in my purse,

but if I did, it would have a car seat.
