This PetSafe original self cleaning litter box works well.  It was very easy to set up, and the instructions were understandable.  I have had the litter box set up for about 2 weeks now.  The litter has held up well.  My cats seem to really like it. They had no issues with the texture of the litter.  The area the cats use is large and not confining at all.  There is no smell from the litter box.
     The rake does not always catch all of the solid matter, and it gets trapped between the rake and the end of the box.  The disposal of the used litter seems very easy, although I have not bought more of the special litter yet to change it.  
    The ScoopFree litter box works as it claims, and for multiple cat homes it is great. [This review was collected as part of a promotion.]
