Fantastic!
I used to buy catnip for my cats and while they enjoyed it, it was only for a short moment of fun. Also, one of my cats reacted to catnip weaker than another. I tried these silver vine sticks and they are just what we needed! They work stronger, and last for a few days. I would recommend to remove the bark with a knife, as the sticks tend to dry out in storage, but uncovering the living tissue inside resolves this problem. 10/10!
