I can't use the washable ones, bc the pee spreads and it doesn't dry. Mine are home for 10 hrs, and this doesn't work for us.
I use throw away pee pads. I buy (from the dollar store) a box of 100 small plastic diaper baggies and I fold up the pee pads really tight into the little plastic diaper baggies and tie in a tight knot. This little baggies actually have a gentle powder smell, so this solves that gross pee smell in the kitchen garbage
