My 1+ year old spayed mini rex has suddenly forgotten that she is litter box trained. Except for when I first got her a year ago, I have never had a problem with her urinating outside of her litter box. She normally has no problems. She is in her cage while we are gone to work, but we let her out either to roam in the office or in the living room, wherever we are going to be so we can play with her and keep an eye on her. The other day, she just up and pee'd on our TV stand & floor. I noticed the next day that she had also urinated in her cage, outside of her litterbox. I cleaned out her entire cage then, and noticed again yesterday she urinated in her cage. Sure enough, tonight she urinated in the living room again too.

Her behavior is normal. Her eating habits are the same. Nothing has changed in her daily routine. I hate leaving her in her cage, but my husband is not happy about the urinating around the living room thing. I don't know what to do. Any suggestions?
