If you live in the United States, this plea is made of you
While possums are invasive species in other countries, like Canada and New Zealand, the North American possum means you no harm if you’re living in the US.
However, if they still scare you, this little fact might make you feel better.
Most people know that possums, well, “play possum”, meaning they “pretend” to be dead if they are frightened. However, characterizing it as playing or pretending might make it seem as though it is a conscious and devious trick. In reality possums do not have conscious control over this behavior, so it would be better characterized as going into a dead faint. This means that the possum won’t spring back to life and bite you if you approach it while it is “playing” dead. Rather, you can move it somewhere else and it will eventually wake up, a couple hours later. If it’s in your house you’ll probably want to do this sharpish, because part of their playing dead routine is leaking a nasty smell from their butt to mimic the smell of a rotting corpse. Once you see them twitch go ahead and leave them alone, and they’ll wake up and wander off.
I wouldn’t mind having a possum in my garden, if only to make a dent in the ridiculous number of slugs I’ve got taking over the place. There’s no reason to fear it just because it has an ugly little face. Still, if you’re not convinced of it’s trustworthiness given it’s freaky grin, always remember that it is the cousin of these furry little cutie pies
That second one is actually called the “little wooly mouse opossum”. That’s just too cute.
