What a concept... I think we may have to try that. Mia is only 4 months. She goes potty (pee) on a pee pad but it's hit and miss with the other. I was thinking of using a cat box with a lid. Has anyone ever done this before? I also put baking soda on the area that she pottied on, I leave it for about 15 minutes then vacuum and it seems to soak up the smell.
