Catnapper,

The catnip was probably stale. Whenever my friend Kathy gives me some of her fresh stuff out of her garden, I hang it to dry and then put it in a ziplock baggie and stick it in the freezer.

I've tried growing catnip from seeds and it didn't work. Kathy said she'd give me a grown plant to stick in the ground. I'll let you know how it does.
