I generally get my Cat Nip from catfamily in Maine, who donate half to the Animal Welfare so they can make thier great Cat Nip Toys.
Thank You again Carla and Mike.
I would be careful of pet store Cat Nip, as it may have been of the shelf for a while.
Make sure that the Nip is green, and has an odor.
Good Luck Nip Hunting.
