Teacup, if she is housebroken, and wetting now, then she may have a medical problem. Animals have this tendency to drink a lot of water when something is bothering them. Nature tends to want to flush their system out. If she is doing this excessively or more than normal take her to the vet, explain the situation and have them do an exam. This is a sign to the start of so many problems.

While she is there and you live close enough, go home, and place baking soda and an absorbant towel on the wet area to absorb the urine. Vacuum up and add more soda with a little water and repeat. Once you have all the urine up, then get an enzyme cleaner and spray the area, then let sit for a few minutes. Absorb with papertowels and let dry. You do not want your pet to notice you are interested in their spot. It does creat marking problems.

Hope this helps.
