Recreational Narcatics Catnip is a cut above the other cat drugs out there. Our plants are not harvested until they’re nice and mature because that’s when they boast their highest levels of nepetalactone, as well as essential oils and blooms. Nepetalactone is the chemical that is responsible for sending cats on a frenzy of excitement. The toy mouse adds more fun! It is packaged into pellets; this helps to maintain freshness and creates less mess. Pour the pellets into a dish or scatter in an empty box. The pellets can also be easily crushed between your fingers and sprinkled for our feline friend.
