This possum turned up on the porch. I thought my dogs had killed her, but I could see she was still breathing.
Turns out she was "playing possum" but I saw that she had this around her neck. You can see that it must have been on there for a long time. The plastic had cut about a third of an inch into her skin.
So, I cut it off.
Then she sat up, motionless for about a half hour.
I've never see an animal look so dejected.
Finally, about thirty minutes after cutting the plastic off, she walked down the steps and into the woods. I hope she's doing alright.
