Kong loves cats and created these safe, high quality toys without elastic, strings, mylar or exposed bells. Ever wonder why your cat won't play with most new catnip toys? Ever wonder why some are so cheap? Most catnip toys use inexpensive stems and stalks - the parts without aroma that SHOULD be thrown away. Kong Cats With And Attitude toys are filled with only the finest North American catnip. And, as a bonus, you can open the patented hidden closure and refill the toy with Kong's mess-free catnip packets after the old catnip has lost its strength.
