From the catmint plant, Nepeta cataria, we get catnip, which drives many of our feline friends mad.
This necklace depicts nepetalactone, the many molecular constituent of catnip essential oil. While the exact mechanism of nepetalactone isn't yet known, it is likely that it is very similar to cat sex hormones, and affects the cat brain similarly. It affects wild cats (like tigers and leopards) as well as domestic cats. In humans, catmint has a sedative affect.
As a bonus, nepetalactone can also repel insects.
The necklace is made from high quality, solid sterling silver. The pendant is about 1 inch (3 cm) long and dangles from your choice of chain: 16, 18, or 20 inch silver snake chain or 16, 18, 20, 22, 24, or 26 inch black cotton cord. It comes in a recycled paper gift box with a info card about nepetalactone. A great gift for a cat-lover!
