kp_23,
I use Nature's Miracle Stain & Odor Remover. I wipe with it and/or spray it on the floors if Cookie decides to put her nose on the peepee pad but pee off of it...
You could consider using one of the pad holders...maybe Nala would be less interested in it if the edges were held down by the holder....Good luck!!
