Nepetalactone is the organic compound in catnip that causes your kitty to go wild, that is, unless your particular kitty lacks the 'nip gene. One in four cats will never do 'nip; they're just not interested. Cosmic Catnip Bubbles are made just like regular bubbles, but with the addition of catnip oil for maximum kitty craziness. Each bottle contains 8 ounces of bubble solution and a bubble wand for you for optimal bubbly Nepetalactone delivery.
