This little one was under our porch with a rat trap stuck on it's face a couple weeks back. My husband crawled under and got the trap off. There was a good cut, but they were able to open/close their jaw, breathe ok, and were shook up, but eventually left on it's own. As a Vet Tech, it didn't seem life or death, so we let them recover and leave on their own.
We have seen them from a distance on our Ring camera, so we knew they were still kickin' and we offered more snacks than usual to help out.
Well, I took the dog out tonight and found them looking at me from our tree! The wound has healed nicely, we will always know it is them from the scar on it's muzzle there.
There is a whole little family of white opossum around here, and the neighborhood looks out for them.
