I have purchased the Out brand pee pads for the past 2 years and they have worked pretty well. Recently Walmart started selling a different brand called Simple Solution. They sell for several dollars more than the Out and you get quite a few less for the price and the darn things leak! I'm just warning you and everyone else not to use them. I use the Out puppy pad frame that I purchased when I first got Gracie so thankfully my floor has not been ruined. I do, however, have to clean the tray every time I change the pad because the urine runs right through the pad. Warning! Warning!
Best wishes on your new family member and happy potty pad training!
