I made a keyhole bed in my home garden with a hardware wire tube in the center for scraps. The wire tube is topped with a plant saucer so no critters can get in except my decomposing little guys. Also safe from vermin are the worm bins.
Yard litter and trimmings get the pile treatment. No furry critters! (This year I topped the branch pile with soil as a pseudo-Hugelkultur bed which is now spiked with sweet potatoes. Franken-gardening experiment!)
