<< apparently its bad for them. >>
I've read everywhere that catnip is harmless. Cats in nature eat catnip about once per week - and they don't go crazy. In the home, cats have no access to this mint and they go crazy if you suddenly let them smell/eat it. However if you keep catnip around easilly available to the cats, they basically ignore it as they weren't deprived. Do you have any proof that it harms them?
