My kitts had broken the door on their old box, so I bought them a new box. It's a sift & sort litter box, and your not supposed to even scoop with it. It has a collander type square tray that sits under the litter, and you pull it up through the litter and shake a bit, and all the loose litter falls into the pan again, and the poop/pee etc is in the tray for dumping. Sounds great right? Well, so far it's not so great. The problem is, the pee clumps throught the grated part, and I end up with giant clumps frozen to the grated tray. So I had to hunt for my old scooper (as I gave the box with the broken door to a rescue group), the whole time fighting Louie out of the box, and scrape the frozen clumps of pee loose, then dump into a trash bag. Which ended up with litter all over my floor, as I had to violently scrape it loose and dig it out. The other problem is that even though I scraped & scraped, there was still debris clinging in between the slots. Really it needed to be washed thoroughly, but I was without any help at that time, and so I just put it back in for the meantime. I can't "wash" it in my bathtub or sinks cause of our old old drains, and I don't have a hose hook up. So does anyone have a solution?!?! Please help, as this is becoming waaaaaaay harder than the regular litterbox, that never got litter everywhere!
