Our cat Henry was crazy about catnip and always reacted very strongly to it. My father, who pretended not to like cats (even while Henry sat on his lap and purred), didn’t approve of catnip. “What are you trying to do to him?” he once asked.
But catnip is harmless to cats. Our cats Robbie and Peep don’t react to it at all, but most cats do–as you can see in this video.
Mr. Nature adds: “Lacewings are attracted to catnip just as most cats are; and the lacewings eat the mites and aphids that trouble the catnip plant. As Rev. D. James Kennedy used to say, ‘Ain’t chance grand?'”
