Well that may explain an interaction between a possum and my sisters dog a few years ago. When I lived with my sister I’d take their mastiff out on her leash and walk her around their property while I had a smoke. We’d do this all times of day and night.

I’d drop the leash if we were in the backyard since it was fenced on two sides and only one gate to get into the front, which I could keep an eye on while she explored. One night, it had to have been about midnight, she was obsessed with this one spot in the tall grass, like, would not leave this spot. So after about five minutes I went to grab her, and she’s fighting me, nose buried in this spot. I finally turn my flashlight on and walk over, and there’s a possum curled up in the tall grass. And she’s licking it…

I pull her away, since, I’m sure dogs shouldn’t be licking wild animals, especially ones that are dead, right? Like, only a dead possum would let another animal lick it, right? Wrong. As I’m looking at it to make sure she didn’t lick up any maggots or was eating any rotten meat, it turned it’s head towards me, eyes squinting, like, “Do you mind? I was having the most wonderful dream of a bath.” It wasn’t playing possum, I’ve seen them do that, it was literally just curled up in grass, sleeping, while a dog 6X its size was licking it head to toe.

One researcher decided to dissect dead opossums’ stomachs and analyze the contents. First off, they don’t eat ticks like people assume. Secondly, she found things like broken glass and a partially undigested shrew. Source.

In conclusion, opossums are metal.
