Your feline friend will love these safe, high-quality toys from Dr. Noy's Pet Toys. Cats with an Attitude cat toys are filled with only the best catnip on the market, not the aroma-less stalks and stems that should have been disposed. As an added bonus, each Cats with an Attitude toy can be refilled with pre-packaged, mess-free T-Nips Catnip refill packets, once the old catnip has lost all its flavor.
