It’s been clear for a while that a comadreja (possum) had been getting into our compost barrel.
Its last visit was indeed its last.
Since lately I’ve only taken compost out after dark (without a light), I don’t know how long it had been there. But I expect I would have heard it moving when I emptied scraps on top of it. The last time this happened, I actually tipped over the barrel so it could escape.
I just recently bought a book, Compost Everything: The Good Guide to Extreme Composting, whose author would have left it there. I’m not there yet. I took it to the overgrown corner lot to let nature do its thing there.
Obviously it couldn’t climb out. But why did it die?
