I was wondering if anyone on here uses a self cleaning litter tray? If so, which is a good one? They seem quite expensive so I don't want to waste my money on something that doesn't work!

Also, which hooded trays are good? I have only ever used a tray with my previous cat so don't know much about these. Are they easy to clean out? How bad the smell hit you when you remove the top cover?

Kori
