Also, they are very dangerous disease carriers.
I've forgotten what is in their scat, but it's bad stuff. The biggest problem, though, is rabies. Rabies is a disease native to raccoons, so they don't die of it. They're just carriers, so you don't want to get bit by one.
On the other hand, when I was a child on the farm my dad shot a raccoon and my mother cooked it. I considered it delicious. I've been tempted to cook one, but I'm not sure what the health risks of city raccoons are.
