I was worried about changing my everyday cat litter in a cat box to the self-cleaning litter box.  I thought that my cat will never use this or know what it is since he never used this kind of litter before.  I was so shocked that my cat used the self cleaning litter box as soon as I left the room. I really like how the self cleaning litter box operates by cleaning the litter area for the next usage.  My cat uses this all the time now.  No more scooping out litter box.  I plan on using this for my cat from now on.
