I absolutely hate cleaning litter boxes. I think I need therapy.

I have the 4 cats and I have 8 litterboxes placed throughout my basement. I have 8 boxes so I don't have to go down as frequently to clean.

Anyone have any good suggestions on how to cope with this much cat poop and pee? The cats are all very good about using the boxes and only on occasions someone "poops outside the box".

Anyone use the Littermaid? I have thought about getting one or two of them but am concerned about a malfunction.

Any other good suggestions would be much appreciated!
