I like to buy toys from time to time to keep the cats interested and, even though they love their Zebedee catnip mice, they have found that other catnip products can also be of interest - as long as I know that anything else is an addition and not replacement for Zebedee, of course.
Anyway, they tried out this particular toy a few months ago; well, when I say tried out, they actually just ignored it. It is quite large and I suspect that is the main reason for the lack of interest, although they are usually keen to checkout anything catnip related and even the catnip content of this failed to engage them even for a moment. The best reaction they gave was to briefly sniff the toy before snuggling down to sleep facing the other way. Even the strung version on a pole did not make them engage.
Perhaps I just hit the jackpot when I found Zebedee catnip mice several years ago, a toy that all of the cats simply love; this Hugga Wubba has fallen short of their (probably very high) expectations. Other reviewers cats seem to love this, so it is possible the ones I had were old stock and no longer had the enticing catnip attractant, but I wont be trying any more for my cats.
