Jaime,
If I understand you correctly, they ONLY pee on Samantha's bed. Why don't you just forget about Samantha having a bed??? I had someone peeing on this rubber backed rug I kept in the kitchen. I loved it. I threw the first one out, and bought another. Yep, pee, pee, pee. I finally just got rid of my need for a rug in the kitchen. Overly simple? Yes, but, it solved my problem.


Just a thought...
