We have some made by Nature's Miracle and we found ours at all the local pet stores around here ex: Petsmart, Petco, Pet Supplies Plus, etc. I I couldn't smell a darn thing but maybe Izzy does...lol. I only use them now for when we are gone all day at work since she goes outside....we used regular ones too and no different so if they are higher in price in your area I would say to save your money and buy the plain unscented ones.
