Snarky Lady's Assistant gave me a little bag of catnip, which I tucked into my purse. I didn't think about it again until tonight when I got home, and shortly thereafter, Hermione was lying on my bed ripping away at the purse with her mercifully short claws. (Purse is a $7 walmart purse on at least its second season. I don't do the fancy purse thing.)
Her cat tree, which she's been ignoring, now has some of the 'nip sprinkled on it. She was paying attention to that, at least!
