I was going to post facts about possums, like how they eat cockroaches, rotting fruit, and slugs, and how they hiss and bare their teeth when threatened (so do I), or go limp, since they have no defenses against predators. But then I found this great YouTube video called In Defense of Opossums, which does a much better job than I could.
Did you feel badly for the possums in my story? Would you have felt badly if they had been rats? No? Then please visit http://opossum.craton.net/ You can view the video there. It plays the Rocky Theme, not sure how that fits, but the video is less than three minutes, and worth the time.
Possums are a protected species in their native Australia. Do yourself a favor and find out why!
