Today's "before" is the compost heap - household waste and all those nettles and thistles I weeded out in the summer, now much reduced in bulk. I tried hot-composting, but couldn't get it to heat up more than 5C above ambient temperature.
Anyway, the rats. They just love the compost. Last week's vegetable peelings and bits from the chicken stock thrown on top of the heap were all mysteriously disappeared the next day. And I've twice seen rats in the vicinity - it's a rule of thumb, rats are ubiquitous, but when you actually start seeing them in daylight, they're overabundant and getting cheeky.
I've inherited from The Predecessor lots of grids of wire about 3x6ft. I dug down a spade's depth, and then lashed 4 of the grids together with wire, and put them in the hole I'd dug, refilling it. It won't be deep enough to keep a determined rat from tunnelling beneath the new compost cage, but it might deter the blighter somewhat.
And I should add, finally, that my compost as I forked it into the cage had that surprisingly pleasant odour which good compost should have.
