Possums are an evil foreign pest who love eating our native flora and fauna. Place isn't quite *overrun* with them, but we do probably have more of them than say, humans, cows, or even sheep. They have no natural enemies here, which gives you an idea of how fricking *pansy* our native fauna are. Not sure about the cheese to tell you the truth! Edam, at a guess. Or a mild cheddar.
