What is catnip?

Catnip, also known as catmint or Nepeta cataria, is a perennial herb that belongs to the mint family. It's native to Europe and Asia but can be found in many other parts of the world today. The plant produces small white flowers and has a distinct smell that is irresistible to cats.

Apart from sending cats into a state of euphoria, catnip has a rich history of use in traditional medicine. It's been used to brew tea and relieve coughs in humans. More interestingly, it's a common ingredient in natural bug repellants.

What causes catnip to have its effect on cats?

The true enchantment of catnip lies within a single compound: nepetalactone. This natural chemical, found in the plant's leaves and stems, is the key to catnip's captivating effect on cats.

When a cat encounters catnip, nepetalactone enters the nasal tissue and binds to receptors that stimulate sensory neurons leading to the brain. Remarkably, these neurons evoke reactions akin to feline 'happiness' hormones, triggering a state of euphoria or intense joy.

Contrary to popular belief, catnip doesn't 'intoxicate' cats in a human sense and is not addictive. It simply stimulates a pleasure response. While humans can detect catnip's lemony fragrance, they lack the receptor response that generates this unique feline euphoria.

How does catnip affect cats?

When exposed to catnip, many cats enter a state of euphoria, displaying behaviors such as rolling, flipping, rubbing, and purring intensely. For some cats, catnip brings out their predatory instincts, leading to animated play and hunting-like actions with toys.

On the other hand, some cats experience a more subdued response, becoming calm and serene. Interestingly, the reaction to catnip is brief, typically lasting about 10 to 15 minutes, after which the cat becomes temporarily immune to its effects. This temporary nature ensures that catnip remains a safe and occasional pleasure, without the risk of overstimulation.

The diversity of catnip among cats

The intriguing aspect of catnip is that not all cats respond to it in the same way. In fact, sensitivity to catnip is an inherited genetic trait.

Around 50-70% of cats exhibit noticeable reactions to catnip, ranging from playful rolling and frolicking to a more serene and contemplative state.

The response to catnip is response is genetically determined, hence the reason why some cats are more affected by it than others and some cats don't respond at all.

Are all types of catnip the same?

No, all types of catnip are not the same. The potency and impact of catnip can depend on its form. Fresh catnip, for instance, is usually more potent than dried catnip. The fresh leaves of this herb contain higher levels of the volatile oil nepetalactone, which is the compound responsible for triggering the unique reactions in cats. Dried catnip, while still effective, often loses some of this oil during the drying and storage process.

The practical uses and benefits of catnip in cats

Catnip can serve as an excellent tool to manage your cat's behavior. For instance, it can encourage your cat to utilize a scratching post instead of your furniture. It can also help alleviate stress and anxiety, making it useful during travel or when introducing your cat to a new environment.

Additionally, incorporating catnip into interactive playtime routines is an effective way to bond with your cat and provide mental stimulation. It can also be used as a training aid, where you reward desired behaviors with a small amount of catnip.

At our animal hospital, we routinely use catnip for our hospitalized patients. By allowing them to be exposed to catnip in a toy or on their bedding, we can help reduce stress and anxiety during their stay.

How to introduce your cat to catnip?

Introducing your cat to catnip is a simple process that usually results in instant gratification. Start by offering your cat small amounts of dried or fresh catnip, either by sprinkling it on their toys or scratching posts, or placing it in a secure area for them to explore.

You can also try introducing your cat to catnip through interactive playtime, where they can smell, roll around in, and even consume the herb. Keep in mind that not all cats respond to catnip, and it is more prevalent in younger cats than older ones.

Additionally, it's essential to monitor your cat's reaction when introducing them to catnip. While most cats typically have a positive response, some may become over-stimulated or display aggressive behavior. If this occurs, it's best to limit or avoid giving your cat catnip in the future.

Can catnip be harmful to cats?

Catnip is not toxic to cats and does not pose any harm if ingested in small quantities. However, consuming large amounts of catnip may cause vomiting or diarrhea, but this is using self-limiting once you discontinue exposure to catnip.

Catnip can cross the placental barrier if ingested so it is recommended not to allow pregnant cats to consume catnip. Additionally, there is evidence that catnip can adjust the seizure threshold and therefore we advise against giving it to cats with seizures.

What are the most common forms of catnip you can give your cat?

There are several forms of catnip available, each offering unique ways for your feline friend to interact with this intriguing herb.

  1. Dry catnip: This is the most commonly used form. It's easy to sprinkle on toys, scratching posts, or beds.
  2. Catnip spray: This is essentially catnip oil diluted with water and can be sprayed on your cat’s favorite places or toys to attract them.
  3. Catnip stuffed toys: These are toys filled with catnip. Cats usually respond by batting, kicking, and wrestling with these toys.
  4. Fresh catnip: If you're keen on giving your cat a natural experience, you can grow fresh catnip plants.

Remember, the appropriate form will largely depend on your cat's personal preference and how they react to it. It's also important to note that moderation is key, so it's advisable to give catnip as an occasional treat rather than a daily supplement.

Is catnip safe for kittens?

While catnip is safe for kittens, they typically don't respond to it until they reach 2-3 months of age. The sensitivity to catnip gradually develops and may increase over the years.


In conclusion, catnip, a non-toxic herb from the mint family, holds an enchanting appeal for many felines, inducing a euphoric state through the compound nepetalactone. While it causes varied reactions from playful excitement to serene relaxation, not all cats are affected due to genetic predispositions. The potency of catnip can differ with fresh catnip being stronger than dried, and its practical uses range from behavior management to stress relief. Catnip is generally safe for cats, though overconsumption should be avoided, and it's not recommended for pregnant cats or those with seizure disorders. Available in multiple forms, catnip can be a delightful treat for your cat when used in moderation, enhancing playtime and bonding experiences.
