They're working just fine!
Sorry about the reply delay. Haven't checked back in months, but here are "lessons learned."
1.) These pads are absolutely fabulous on our hard tile floor. We use them for a week at a stretch, with a "playpen" made of 15 cubes cable-tied together. Most days, the little guys spend 12 hours a day out on the floor, in the living room, with us (we've made them a Coroplast house to give them some security)
2) In the actual C&C cage, the triple-thickness folded pad gives them a wonderful surface to pad around on. All piddles are immediately absorbed, and they stay "inside." However, the triple thickness means we can start to smell the bedding after about day 5--so we returned to pine & carefresh there.
3) HOWEVER, with our piggers outside with us most of every day, we go through only one carefresh bag per month.
4) The utility pads are easy to wash at our local laundromat--$5 in the Huge Industrial Washer takes care of them.
5) NEVER, EVER put them in even a cool dryer. Ugliness and melting of the nonwoven cover results.
6) We love the pads so much we just went back for a couple more to replace our laundry casualties--and were upset that our local supplier can't get them anymore!
I did just see them for sale @ $10/apiece on Ebay. Search for "Kimberly Clark" pads.
Best to all. We really love these things and can't imagine why K-C isn't repackaging them to sell them at pet stores for 3x the price as "puppy training pads."
