To complement (in some way I haven’t worked out yet) our office dog, we have an office wormery. I can’t comment on whether the office dog has been wormed recently or not.
As it fills up with kitchen scraps you apparently add extra trays, and the worms crawl up through the trays in search of new food. The bottom tray can then be temporarily removed to extract high-grade compost that has trickled like fine sand down through the layers. It’s testament to man’s ability to forget things that utterly disgust him that I always react with surprise when reminded that fertile soil is actually, when all’s said and done, largely worm poo.
