Everyone has a weakness. For me, it’s salted caramel ice cream. For my dog, Lulu, it’s expensive shoes. For most cats, it’s catnip. Here are some things every cat lover should know about this mysterious product that drives cats batty.

Catnip is an actual plant

A member of the mint family, Nepeta cataria L. (aka catnip) grows throughout the United States. The plant features small, lavender flowers and jagged, heart-shaped leaves that smell faintly of mint.

It’s easy to grow

Cat lovers who possess a green thumb can grow catnip from seed after the last hard frost of the season. As a perennial, this herbaceous flowering plant will return each year with proper care. Keep in mind that catnip requires plenty of room to grow and flourish, much like most felines. Once it grows, you will have the most popular house in the neighborhood — at least among the feline population.

Use with care

Once cats get a whiff of catnip, it’s best to leave them alone until they’ve lost that loving feeling. Catnip also can cause excessive drooling, so you may want to retrieve those cat toys after use. No one wants to step on a soaking wet cat toy. Burgoon also suggests storing catnip and catnip-laced toys in an airtight container or a cat-proof area.

People like catnip, too

Catnip also can be used for tea. The presence of a chemical called nepetalactone produces sedative-like affects in humans, making catnip a popular home remedy for headaches as well as insomnia. To make catnip tea, add one teaspoon of dried catnip leaves or three to four teaspoons of fresh catnip leaves to a mug of boiling water and let it steep.
