Depending on the size of your home you might want to reconsider having your litter boxes at different places rather than all at one place. Think of your home from a cat sized perspective. it could be a LONG way to go to the other end of the house when you gotta "GO".

Having a litter box in a bedroom, kitchen or wherever is NOT a bad thing. People sometimes have this "stigma" about where the litter MUST be. I have boxes in EVERY single room in my house and they are not an eye-sore, they are part of my home and decore, part of my lifestyle.

But if you actually NEED to move the box, don't do it until she is older and more able to hold "it" in case she forgets that it is no longer there and needs to race to the other one.
