Yesterday at Pet Smart, I saw a Dome litter box that had a ramp inside to get the litter off their feet as they walked out... I thought that would be perfect for Amy since she has trouble some days stepping out of the big box with cover. On her bad days she has to drag her back legs out of the boxes I have.This one has a cover too, but they are SO big that I don't have room for something that big...

My neighbor has one of those self cleaning boxes and her old 9 year old uses it but if it is cleaning, he won't go near it. I think they would get use to it if it is kept close to the other one but it may take awhile so don't give up.. My neighbor said that was the best investment she ever made. She is disabled and can't do the stoop to scoop...
