I'm sorry you have been going through this with your girl. It seems that she has been dealing with the stress of moving and your emotional stress as have you. (Animals can sense more than we realize.) It seems as if she responds to tile flooring. Here's what I can suggest for now. Place another litter box in the area right where she was inappropriately eliminating. You mentioned that she only goes on carpet, so using tile underneath it is the best bet. Also, if all else fails, contact your vet regarding this problem. Certain medications can also aid in correcting this problem. PLEASE let me know if I can help you any further. I have dealt with this many times with clients over the years and have come to a positive result!
