This litter box system is absolutely wonderful!!! I used to have to scoop the box out 1 or 2 times a day. Not anymore. Now it's 1 time a week! 
The crystal litter absorbs the liquid & contains the odor for a lot longer than the clumping litter. No more constant buying & lugging those heavy containers either. In fact, you can have the litter trays delivered to your door. Plus, you only have to change out the old litter tray with a new one every 3-4 weeks.
Loving this fantastic ScoopFree self cleaning litter box. [This review was collected as part of a promotion.]
