Nice! Out of curiosity, did you or have you ever tried a bit of cat nip? I no longer have cats, my two girls died a few years ago (at over 20 years old, still miss them).
Anyway, I think it may have been worth a try with one of them, catnip made her a slow, dreamer kitty. The other one (usually very subdued) became a kamikaze cat under the influence, though!
