I have used wahsable pads for almost a year now. Like WOW! What a savings in pee pads. I use the reclaimed ones from http:
www.valethics.com -- they are not very pretty but they are very serviceable and have a terrific rubber leak proof backing. I generally buy the S27 type 32 x 27" but they are out of stock.
There are several members who make washable potty pads that are very attractive and will fit in with your decor
