I have a catnip spray that I use on Maddie's scratching post so she remembers that's where claws get sharpened - not on the settee. I also spray her catnip mouse with it, every now and then, to boost the smell.
Maddie gets "high" on catnip and rolls around with a dopey expression on her face. It's a similar reaction to her shoe fetish and, I'm afraid, she's now a hopeless catnip junky.
