What is the deal with this catnip or liquid catnip? I have no interest in toys with it built in, and they don't sell it at the Walmart or anything near me, and I wont support the petstores that encourage mills... Why do u guys love it? And I started to refuse treats. I dont like catgrass, except to throw the earth around the apartment (and I dont touch the other 30+ plants in this tiny place)... any one have any suggestions to whats the deal with this catnip??
