Actually, some cats have the "catnip gene", some don't, my spayed kitty LOVED the stuff, she would go absolutely bonkers for it, so does my neutered male I have now. They say the kitties that respond to it, that have babies, their babies will respond to it, once they are old enough. Regardless of gender or if they are fixed. Their are other plants cats like, try doing a search for "Plants cats like". It's not just catnip.
