So far, the patio cats haven't shown much interest in it. Heidi, for example, slept next to it but didn't do anything to the leaves. Aren't cats supposed to go "high" on it?
I haven't tried it on Bunny & Friends yet, but I will...soon. Just a bit "sayang" they might kill the plants in their state of ecstasy!
For seasoned catnip users, please advise how I am supposed to use it. On the cats, I mean.
