this review title is: only cats liked it and the content is: of my cats regularly walk under a u shaped wire brush toy to groom themselves another likes to go chew on the brush the cat always grooms his chin on a prickly squishy ballthe brushes that arrived are hard plastic instructions were not included so i had to revisit the website before pouring catnip in the back of the wall brush everyone sniffed it but only tried to rub up against it at first i had it secured to the bottom of a stool but once i attached it higher up the legs the cats nudged at it it s been in the cat room for over a week the cats have not paid it much attention i moved near the other grooming toys but no improvement maybe the catnip is not so potent or maybe i need to pour the entire bag inside not sure will continue to move brushes to new locations see if interest gets peaked.there are other information for this review, one is this reviewer did not purchase it and the other is 0 people think this review is helpful.
