The toy with tinsel on the end of the pole....I have to HIDE that because my cats will do ANYTHING for that !!!!! And they know where I hide it, if I even go near where it is they start to drool. Both Sterling and Jasper will turn in circles until they fall over if I wave it around that long. They actually pant !!!! And catnip toys are a big hit. as are the small balls that look like they are made out of christmas garland. And fur mice, too.
