I had until now used to using the true catnip, which I rubbed on toys. But we found grass ground, cétait not necessarily very practical, even if it was effective. This is ideal and the effect is stunning: the cat reacts presto! This is perfect, especially for indoor cats, is sprayed on the scraper or toy and Mr. lets off steam thoroughly on, he fights with his toy, rubs. Super felt happy. No need to buy new toys, once those we already have lost their attraction (because they no longer feel catnip): just spray a shot, and that's go again !!!
