I don't use NM brand pads...I use the blue/green bag from Wal-Mart, and the girls are really good about using them.
If there is an actual "scent" to them, I suggest that you return them to where you purchased them and see if they will give you a refund since they're not working. I know PetCo and Petsmart will both exchange/refund if something doesn't work. |
