Space-Age Litter Tray
This has got to be the most over top litter tray ever invented, the Litter-Robot.
The litter-robot looks like a feline spaceship and hygienically removes you pet’s poop from the tray each time it goes. So the cat goes into the ball to do it’s business. Once pussy has finished it vacates the sphere. Seven minutes later the sphere rotates dropping the er droppings into a drawer below, which you can then empty on a weekly basis (gas mask recommended).
There is an interesting demonstration animation and you can buy online at Litter Robot, it costs £299 though so it may be cheaper to train your cat to go in next doors garden.
Via Ounae and Apartment Therapy, thanks.
