Query: Worth Every Penny!!

I had given up on so-called "automatic" and "self cleaning" litterboxes. I tried both of the leading raking litterboxes and found myself needing to stick my hands in the thing daily to "ungunk" the rake or to free it when it got stuck. Then I stumbled across this bad boy - more expensive yes so I took a huge gamble and man did it pay off!!! I have been using it for more than a month now. My fairly large Bengal took right too it (I just filled it with his normal clumping litter and put it in the same place as his old box). This litterbox NEVER jams or sticks and is very quiet. The sifting and tumble system is awesome ... the litter always looks brand new!! I empty the catch tray about every two weeks (and this is truley a "hands off" task ... just tie the bag shut and throw it out ... way cleaner that the raking models). The price is high - but I feel it is truley worth it!
