Howdy, neighbor! We use washable potty pads here -- I get mine from
Used Waterproof Pads . I have been using the same pads (222-2732 27x32 Minimal or None Minimal or None Minimal or None Most popular, Best Value $4.95) for the past 3 or four years. I have accumulated enough pads so that I only wash full loads about 3 times per week.
I would also like to promote our YT Sellers -- there are several that offer Washable Potty Pads. Some of our sellers will even custom make pads to coordinate with your color scene. If you don't get the information you are looking for, do a search on Washable Potty Pads and you'll a lot more info.
