With the busy schedules my Wife and I have,I always thought a self cleaning litter box would be a big help keeping odors to a minimum. Only problem I was worried about is our cat is afraid of his own shadow and thought he would refuse to use if it made the slightest noise. To my surprise he took to it right away and has used with no issues as of now. By the time litter is raked away he is in another room. Only issue I have is it's a little smaller than previous box and sometimes he sprays over back of box. They make a cover for the ScoopFree box which I will have to get. I've had the product for about three weeks and the litter cartridge is just about ready to be changed, so that makes me satisfied that this product should be a welcome addition to our household.
