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).
