Updated December 20, 2021

We, humans, have a list of vices longer than our arms, but your cat has just one– and it’s actually not harmful at all. Enter, catnip, the plant that turns your Garfield-lazy cat into a swiping, biting, crazed kitten, who can’t seem to stay still. So, how exactly does this plant work?


As strange as your cat’s behavior may become, you can feel safe about letting your cat indulge in this vice – why not give her a little pinch of the stuff right now, and let her bounce off the walls while you educate yourself on what it is and why it causes such a powerful effect on your furry feline friend.

What Is Catnip?

Native to Europe, Asia, and Africa, catnip (Nepeta Cataria: cats wort, cats mint) is a member of the mint family and grows as a loosely branching perennial with fragrant pink or white flowers. Widely considered a weed in North America, as it’s hardy and spreads easily, and is also commonly used as an ornamental garden plant--finally, this plant is easy to grow.

The volatile oil, nepetalactone (a feline attractant), is found inside the stems and leaves of the plant and is believed to mimic a feline pheromone which plays into a cat's enjoyment for a short-lived time.

Not only are domestic cats affected by this plant, but large-breed cats respond, too. Cougars, lynx, leopards – even lions and tigers have a reaction.


What Does Catnip Do to Cats?

The plant itself binds to a cat’s olfactory receptors which are responsible for sensing chemicals called pheromones. Cats can have varying responses to the plant, depending on how they are exposed.

Typically if this plant is ingested it acts as a sedative, and if it’s inhaled, a stimulant.

Inhalation Effects:

  • Excitement and hyperactivity
  • Anxiety Leaping around Rolling on the ground
  • Rubbing against the plant or dried leaves
  • Pawing at it Licking at it

Catnip Ingestion Effects:

  • Aggression (biting and growling)
  • Euphoria
  • Sleepiness
  • Drooling
  • Purring
  • Meowing

After exposure, these effects can last anywhere from 5 to 15 minutes which is then followed by a refractory period (about 2-3 hours) in which your cat will not be affected by catnip.

Sounds like your cat has a substance problem, doesn’t it?

NOTE: Do not use on pregnant cats, as it’s a uterine stimulant and could cause premature labor.

Why Do Cats Like Catnip?

Pheromones are powerful and drastically affect the behavior of living organisms. Because catnip triggers an attractant pheromone in cats, they can’t help but react in a strong way.

Reaction to this plant is believed to be an inherited trait as about 50-75% of cats are affected by this treatment, while somewhere around 20-30% are not.

Kittens and senior cats don’t usually react to catnip. Some believe they don’t respond because of their underdeveloped or weakened sense of smell. Others believe it’s because kittens and senior cats have no or little sexual activity, making them immune to nepetalactone and the feline pheromones connected to it.

Is Catnip Good for Cats?

This plant carries with it a host of benefits for your beloved feline friend. These effects can vary from stimulant to sedative, so whatever Fifi is feeling, you can give her a little pick-me-up.

From exciting her and getting her up and bouncing around, to soothing her nerves and improving her mood, this is indeed a safe diagnose treat cure to give to your cat.
