Thanks everybody.

I am taking her to the vet tomorrow morning. There are several options which could be causing the accidents. She was diagnosed with a bladder tumor several years ago and has been on Piroxicam to shrink it and keep it shrunk. Up until this point she has had no more issues with her bladder. However, the tumor could have come back so they are going to do an ultrasound tomorrow. Also it could be caused by estrogen levels being too low and they can medicate her for that.

I had this great idea to keep her from being in the carpeted part of my house today. I moved my couch so it was covering the entrance to my living room but facing the kitchen/dining room area so still would be able to jump up on the couch and sleep while I was at work. I didn't think she could get past the couch but the one end must have had a big enough area for her to jump through. Somehow she did get past the couch. She has always been tough to confine to a specific area. She likes the run of "her" house. So, I have to work on that problem some more. If I could keep her confined to the part of the house that is just ceramic tile it would be so much easier to clean up.

I'll update tomorrow after her vet visit.
