I use washable pads in my house. I have one in the upstairs bathroom and one in the downstairs bathroom. I save the disposable ones for when we go out or we go on vacation. I usually dont go more than two days before putting a fresh one down. I got my pee pads for free....i placed a posting on a free recycle website asking if anyone had any hospital pads (cause thats what they basically are) and someone emailed me a couple weeks later saying they had some. I was expecting a few..but she gave me 17 of them!!
