Guaranteed by George came into being to honour the memory of our beloved cat, George. I began growing and harvesting my organic catnip after I noticed the benefit it had on his epilepsy and general health. I committed to growing this valuable herb for all beloved felines as a purr makes days so worth while. Go ahead and give your cat a reason to purr. The chemical nepetalactone in the catnip acts as a mild sedative and the sensitivity to it seems to be inherited. Even large cats like lions; tigers and leopards can inherit sensitivity to nepetalactone. It is niether harmful nor addictive to cats and grows naturally in the wild.
