Updated February 1, 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.

As strange as your cat’s behaviour 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 catnip 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: catswort, catsmint) 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, catnip is also commonly used as an ornamental garden plant.

The volatile oil, nepetalactone (a feline attractant), is found inside the stems and leaves of the catnip plant, and is believed to mimic a feline pheromone which most cats are receptive to.

Not only are domestic cats affected by catnip, but large breed cats respond, too. Cougars, lynx, leopards – even lions and tigers react to catnip.


What is Catnip

What Does Catnip Do to Cats?

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

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

Inhalation Catnip Effects:

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

Ingestion Catnip 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 catnip on pregnant cats, as it’s a uterine stimulant and could cause premature labour.

Why Do Cats Like Catnip?

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

Reaction to catnip is believed to be an inherited trait as about 50-75% of cats are affected by catnip, 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?

Catnip 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, catnip is a safe treat to give to your cat.

Catnip Reduces: 

  • Stress
  • Anxiety
  • Depression 

Catnip Encourages:

Catnip FAQ

How much catnip can my cat have?

A few pinches of dried catnip per exposure is enough. It’s potent stuff and your cat only needs a small amount to become stimulated. If you grow catnip in the house, keep just one plant in your cat’s area to limit her exposure.

Is catnip safe for cats?

Yes, catnip is completely safe for cats. While it’s technically possible for a cat to overdose on catnip, causing vomiting/diarrhea as mentioned above, your cat will recover, and this isn’t a big concern.

Is catnip safe for dogs?

Yes, catnip is safe for dogs. While it doesn’t cause them to go berserk, catnip is actually quite useful for dogs, too. You can use catnip on your dog as a: Mild sedative Diuretic Gastrointestinal remedy (upset stomach) Natural antiseptic

Note: Do not give catnip to pregnant dogs, as it can trigger uterine contractions.

How do I grow catnip?

Catnip grows to be 3’ – 5’ tall and blooms from autumn to late spring. You can harvest the leaves throughout the year.

Catnip grows best in:

  • Full sunlight
  • Well-watered, light, sandy soil

Be sure to promote proper growth of your plant with regular deadheading.

Preparing catnip leaves:

  • Dry out the catnip leaves in your oven at a very low setting OR Hang to dry in a well-ventilated area.

Catnip will crumble easily when it’s ready. Be sure to store it in an airtight container, and keep it out of direct sunlight.

You can buy it from nearly any pet supply store. If you prefer shopping online, here is our selection of catnip and toys with catnip.

Does catnip have any effect on humans?

Humans don’t have the same receptors for nepetalactone as cats do, making catnip largely ineffectual on humans. However, there are varying uses for catnip on humans which include:

  • Insect repellant
  • Herbal tea
  • Cooking Bathing

Note: Do not use catnip if you are pregnant, as it could cause uterine contractions.

Interesting Uses for Catnip 

  • Catnip is an interesting plant, with multiple uses.
  • Herbal tea - similar to chamomile in its calming effects, catnip tea has been known to calm nerves, stomach aches/nausea, and headaches.
  • Culinary dishes - catnip is used as an aromatic herb for salads, soups, and marinades.
  • Potpourri - throw some dried catnip in a bowl and freshen up the place with these fragrant leaves (well out of the reach of Fifi, of course)
  • Bathing - soaking in catnip-infused water has been known to relieve aches and pains. It also acts well as a natural antibacterial agent.
  • Hair strengthener - catnip can condition and strengthen your hair follicles, promoting hair growth (this is possibly due to the high levels of antioxidants in catnip).
  • Insect repellent - Repels mosquitos, cockroaches, termites, squash bugs, and aphids.
  • Interestingly, catnip oil has been deemed to be more effective than DEET, but catnip oil’s repellent properties were not as successful when applied to the skin.
  • Natural attraction - catnip attracts bumblebees, birds, and butterflies because of its fragrant, colourful flowers.

Remember to give your cat catnip in moderation to prevent habituation, and try mixing up the ways you expose her to the herb.
