This is some interesting information. Boney Girl was indifferent to catnip. She did get mild effects, but just wasn't high on her list. Xena will rub on catnip some and get really big eyes. What she really prefers is the flower tops rolled up in a ball and eats them like a kitty breath mint. I grow catnip. I also grow a domestic honeysuckle and have bunches of wild honeysuckle. Plan to look into this and give it a try. Thanks all.
