lots of people used the walmart pads. i've heard really good feedback about them, but i must say i also bought them and i was VERY DISAPPOINTED

. out of 32 maybe 10 or 15 could be used. they tore apart trying to open them. i now use ped pads and they are very thick and so far no leaks. my only problem with them is there huge and i dont want to cut them b/c the cotton inside will show and lucky will go crazy trying to tear it up. but out of all the pads i've used wee wee from petco, walmart, arm and hammer from target ect..... ped pads are the best. maybe its better quality walmart pads in smaller cities not sure why mind were so bad.....
