Does anyone use Pish Pads? I'm trying to switch my puppy from potty pads tp Pish Pads. She's good about peeing on them but doesn't always poo on them. Weird! Also do you think it's bad to have more than one pad down. I have one in the room where they sleep and one in the kitchen. Eventualy I will want to take the out of the kitchen but I'm worried she will keep going there. Any thoughts?
