It has really worked out better for Amy and I see improvements in her from the no stress factor. She still falls over but is not posturing stiffly for awhile before she can get up. I am seeing just how badly stress has effected her and what I may have thought was a decline in her was maybe stress. I am actually seeing her using the regular big litter boxes, including jumping out of them, it has just worked out so darn good for them. Now I am wishing I had done this last year when the vet first suggested I do it and not put them through the car rides and changes.
