I gotta say I've had to avoid more dogs on the road than cats. Dogs seem to be dumber in that respect. Cats occasionally get hit on the road, but usually they have the sense to get out of it when they hear a car coming. Dogs... ugh, some of the dogs I have tried to avoid hitting on the road... It wouldn't be so bad if they just stood there, but they mosey along so you never know if they suddenly turned in front of your car right at the last second when you couldn't see them.
