This is one of those toys that, for some strange reason, delights me to no end. The Fat Cat Zoom Stuffer features a little elastic band in the waist to fit a little pouch of catnip that will drive your cat wild. My cat Dorian loves (and often loses) this toy, and it is his favourite day when I stumble upon it. The toy stands up to a lot of wear and tear, and since the catnip pouch is replaceable, it lasts a very long time. -TC
