This self-cleaning litter box uses a design you are probably familiar with: a few minutes after your kitty leaves the box, a motorized rake moves through the litter in the box, collecting waste that is then deposited into a front container.

Remember not to touch the cat's head first to avoid being scratched and bitten.
