only cats liked it [SEP] 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
