Yep it is all down to good old jeans... some cats will go wild if given a catnip toy others just look on with a 'what the hell is wrong with you' look on their faces. It isn't always the skittish ones that are nip junkies either; Mynx is a very highly strung tortie and she is utterly unaffected but Dad, very noble, 'I'm not playing games' sort of cat absolutly goes wild, we had to confinscate his catnip present at one show cos we thought he was going to demolish the pen! Mynx's mum isn't affected either
