I happen to have four cats. Two of them don't like American catnip it really just kind of sniff it and walk away. One day I was lucky to find silvervine if you have a cat I can almost guarantee that they will go crazy for these sticks all four of my cats even the ones that enjoy American catnip absolutely love these sticks it seems like an odd toy but they go crazy for them and the little mouse has been pretty much everywhere in my house batted around like crazy. If you've never tried this stuff I would definitely give it a try it's fun to watch your kitties go crazy for a little bit.
