Interesting idea, but I'm not so sure that I approve of the mass non-consensual drugging of people's cats.

My thoughts exactly. I have a cat and give him catnip every once in a while. I always have mixed feelings when I see him rolling around on the ground. On the one hand he's in pure ecstasy, but on the other I just drugged my cat.

I'd definitely have some words for any company that drugged my cat without consent.

I'd rather have my cat bring me a dead bird (and I love birds) than flyers; if that happened to me, I would not just ignore it, I would do my part to make it backfire as hard as I can. I have to throw enough unread junk mail away each week as is, you could probably build a little house out of the yearly amount, but using animals for this? For shame. But then again we're already decades past exploiting children, and that's even worse.
