Yes indeed, you can compost rats.
This one made the fatal mistake of irritating my wife by invading the kitchen at night.
Rat. In. Peace.
That’s what you get for eating my pumpkin seeds, vermin.
And of course, I made a video:
Though I didn’t build a full “melon pit” with all the trimmings as described in Compost Everything, this rat will still feed the Seminole pumpkins I planted above its corpse.
Don’t let any potential soil fertility go to waste.
