I know lots of YTers love washable.. and I have one myself for Alfie as our regular potty area... but he has had issues with the in side and out side pottying. So we have been buying throw aways as well just in case for another area in the house that he has decided he also likes to do his business...
Anyways, cheap is good so after spending like $20 on 15 pads from PetSmart we went to Target!! 55 pads (Arm and Hammer) for $13.
