Opossums. They're neat little critters. They eat tons of ticks that carry Lyme disease, can't carry rabies because their body temp is too low, and they're the only marsupial native to North America! They get a bad rap because their first defense is to hiss and bare teeth, but failing that, they just play dead.
If you don't have the predisposition to hate them, you'll find they're pretty cute too.
