Too much catnip?
New cat mommy here, and my two kitties are just old enough to start enjoying catnip. I was wondering how much catnip is good for them, and what is considered too much. They have a few toys that have catnip inside and I know it loses its potency after a while. I was more curious about dried loose organic catnip. I had given them each a pinch of it last week and they loved it. I just don't want to give them too much of a good thing. Are there any type of guidelines or recommended amounts of catnip to give on a weekly/monthly basis?
