If you haven't seen your cat 'under the influence' of Catnip then you've never seen them at their most happy. What begins as excitable meowing usually evolves into a dazed & blissful euphoria, as your cat playfully paws at you, rolls over & splays out on the carpet with a satisfied grin on its little bewhiskered face. It's wonderful to behold. As with anything that gets you 'high', it's always better if you grow it yourself. More control, all-natural, high-purity, isn't cut with oregano etc.
