Like any drug, individuals react differently, and this is especially true with catnip since it as a psychodelic drug.. Some of mine get pretty nasty when they're nipped-up, some lie on their backs and watch the ceiling change colors, and a few don't react at all. Reaction to catnip is genetically controlled; they either have the genes for it or they don't. I harvest some primo wild catnip here and after I strip the leaves and blossoms for their "stash", I throw the stems in the yard for my addicts. It's a free-for-all, and sometimes it gets pretty rough!
Before you criticize someone, you should walk a mile in his shoes. That way, when you criticize him, you're a mile away and you have his shoes.
