Bests & Worsts Reviews from Amazon

I have 2 kinds of cats: a litter flinger and a bolt-n-shake. One digs & flings as far and wide as possible in the process--and occasionally will hang his rump over the wall onto the stairs for good measure, depositing tootsie rolls onto the already-litter encrusted steps for later clean-up. The other cat will do her business and, when done, will leap as far and as fast out of the entire contraption as possible, shaking all four paws in all directions until all litter has been sprayed into all possible corners of every room. So, this litter box is absolutely useless in preventing tracked litter, and also has the added plus of creating more messes for me to clean up on top of tracked litter. The entire litter box is also extremely unwieldy when it comes time to empty & clean, and a hand vacuum is necessary to clean the stairs first, or else litter will fall on the floor as you dump the contents (awkwardly) into the trash bag. My Siamese girl also ripped the charcoal filter out of its holder with her teeth and took off with it. No point in even replacing those, once she discovered THAT little toy...
