I had this years ago for 2 previous cats (now deceased). I wrapped it for Christmas (yes, corny, I know), and the cats could smell the catnip it came with through the package, so chewed on it until I let them "open" it. Then, one paid little attention to it, while the other monopolized it, as long as I could keep the teeny-tiny compartments for catnip filled. My cats very quickly destroyed the gum massager, and cleaning the hair out of the various brushes was time-consuming. Prepare to spill a lot of catnip getting it into the compartments. The toy also takes up a lot of room and is difficult to store. I threw this out a long time ago, have a new kitten now, and will not waste my money on one of these again.
