Hello!!
I usually discard after about 3 piddles.......... but it kind of depends, on how many per day because he also goes outside. I bought a Diaper Genie for the used pads so there is no smell whatsoever in my place
I was using the purina second nature doggie litter box and put the pads in that to save my hardwood flooring.... but have recently switched to the Big Squirt box. I didn't get the grass.... I just put a pad in it and put it in the corner. Loving It!!
