Here's my experience with a pee pad holder:
Never used one. Then, last week, I decided to give it a try. That evening, suddenly, I hear Mandie just going crazy barking at the doorway to the room where it was. I thought maybe she heard something or saw a bug. I turned on the light and then it dawned on me...she was barking at that strange plastic thing sitting in HER SPOT. lol
I took it up immediately because she would never had gone on it seeing as how she thought it was the enemy.
