This morning as I was rotating our lovely organic compost bin, a RAT poked its head up mid-churn (through a hole in the cover that it had chewed for itself and I hadn't noticed). Being a big suck I yelled my head off not because I'm afraid of rats but because I might have shredded poor defenseless rat pups.
I suspect we will have to thoroughly clean the bin and then dispose of what was two years' worth of really great compost. Sigh. And rotate the new batch more frequently!
