Hi Coolcat, I got 'Catnip Leaves n' Herbs' by Hartz in the supermarket at the Centre. It's in the form of dry herbs in a resealable bag with a play toy in which to put the catnip. I'm nearly certain I saw it still there this week. If you can't find any and are in desperate need you can have mine as my two cats seem to be far too lazy to get excited over it!!
