My cat, Simone, didn't take to catnip originally. Someone mentioned that it could have been poor quaility, so I ordered fresh organic catnip from Chewy. That brand is given great reviews and considered high quality.
I tried it out this morning on Simone, and hardly any reaction. She sniffed it and walked away. My thought is that she doesn't carry the gene for catnip. Simone is the first cat I've had who shows no reaction to it. She adores her toys, but couldn't care less about the catnip. It won't go to waste, however, because a friend of mine can use it for her cats.
BTW, Chewy is a great company. I ordered from them before, and have always received the products in a couple days.
