Abruptly changing the location of the litter box can stress your cat out. Don’t do it if you don’t have to! But if you must, do it gradually. One solution is to inch the box to its new location at a pace of about one foot per day. Another solution is to buy a new box and situate it in the new location. Take your cat;to the new box and put her inside it. Leave both the old and new boxes in place until your cat has clearly become comfortable with her new lavatory.
