Possums get blamed for many things raccoons do. Possums are really dumb and they eat grubs. Will they eat an egg or chicken? Yes but it's more of a matter stumbling into food. They don't usually go hunting for chickens etc. Raccoons are smart, they hunt and are very clever when it comes to gaining access to places.
If a critter gets into something here on my farm... I simply ask "did it require cleverness or dexterity? No - possum or skunk. Yes - raccoon.
Lets not leave out the mental midgets of the farm... armadillos, plus they are effectively blind! They can't see a human 10ft away but they can smell one from 100ft. It makes them seem smart. They seem to avoid traps also, smart? No, they are just to dumb to get into most traps.
@Supervisor42 Old riddle, how do you get a raccoon out of a live trap? Put it in the fish pond while you think about it! It'll come to you!
