Catnip is a fascinating plant that has intrigued cat owners for generations. Many cat lovers have witnessed their feline friends suddenly become playful, energetic, or even a bit goofy after encountering catnip. But what exactly is catnip made of, and how does it affect cats? This article explores the science behind catnip, what catnip does to cats, and why it triggers such unique behaviors.
What Is Catnip and What Is It Made Of?
Catnip, scientifically known as Nepeta cataria, is a member of the mint family. It grows wild in many parts of the world and is easily recognizable by its heart-shaped leaves and small, white or lavender flowers. The key to catnip’s effect lies in its chemical composition.
The active ingredient in catnip is nepetalactone, an essential oil found in the leaves and stems. Nepetalactone is a volatile compound that evaporates easily, releasing a scent that cats find irresistible. When cats smell nepetalactone, it binds to receptors in their nasal tissue, triggering a neurological response.
How Nepetalactone Works
Nepetalactone mimics feline pheromones, which are chemicals cats use to communicate. When a cat inhales this compound, it stimulates sensory neurons that send signals to the brain’s olfactory bulb and amygdala, areas involved in emotion and behavior. This stimulation causes the cat to exhibit behaviors such as rolling, rubbing, purring, and hyperactivity.
Not all cats respond to catnip. Sensitivity to nepetalactone is hereditary, with about 50-75% of cats showing a reaction. Kittens and older cats are less likely to respond.
What Catnip Does to Cats: The Behavioral Effects
When a cat encounters catnip, the reaction can vary widely. Some cats become playful and energetic, chasing imaginary prey or pouncing on toys. Others may become relaxed and mellow, lying down and purring contentedly. Here are some common behaviors observed:
Rolling on the ground
Rubbing their face and body against the catnip source
Vocalizing with meows or purrs
Increased playfulness and chasing
Temporary hyperactivity or excitement
These behaviors usually last about 5 to 15 minutes. After this period, cats become temporarily immune to catnip’s effects and need a break before responding again.
Does Catnip Make Cats High?
Many cat owners wonder if catnip gets cats high or acts like a drug. While catnip does cause a noticeable change in behavior, it is not a drug in the traditional sense. It does not cause addiction or harmful side effects. Instead, catnip triggers a natural, harmless response that is more like a temporary mood enhancer.
Scientists describe catnip’s effect as a euphoric state rather than intoxication. Cats do not lose control or become aggressive; they simply experience a burst of sensory stimulation that feels pleasurable.
How Does Catnip Affect Cats Physically?
The effects of catnip are mostly behavioral, but there are some physical responses as well. When cats inhale nepetalactone, their heart rate and blood pressure may increase slightly, similar to the excitement felt during play or hunting. Pupils often dilate, and muscles may tense as cats prepare to pounce or explore.
Because catnip stimulates the olfactory system, it can also encourage cats to groom themselves more or interact with their environment in new ways. This stimulation can be mentally enriching, especially for indoor cats who may lack variety in their daily routine.
Is Catnip a Drug?
The question of whether catnip is a drug often arises because of the noticeable effects it has on cats. However, catnip is not classified as a drug. It is a natural herb that causes a temporary behavioral change through sensory stimulation rather than chemical alteration of brain function.
Unlike drugs that cause dependency or harm, catnip is safe for cats to use regularly. Veterinarians generally agree that catnip is a harmless way to encourage play and exercise.
Safety Tips for Using Catnip
Use catnip in moderation to prevent overstimulation.
Avoid giving catnip to kittens under 3 months old.
Provide fresh or dried catnip, but avoid synthetic sprays that may contain additives.
Observe your cat’s reaction and discontinue use if any signs of distress appear.
Practical Uses of Catnip for Cat Owners
Understanding what catnip does to a cat can help owners use it effectively to enrich their pets’ lives. Here are some practical ways to incorporate catnip:
Encourage exercise: Sprinkle catnip on scratching posts or toys to motivate cats to play and stay active.
Reduce stress: Some cats respond to catnip with calmness, which can help during stressful situations like vet visits or moving.
Training aid: Use catnip to lure cats into carriers or new spaces by placing it strategically.
Mental stimulation: Rotate catnip toys to keep your cat engaged and prevent boredom.
Remember, not every cat responds to catnip, so it’s important to observe your pet’s individual preferences.
Why Do Some Cats Not React to Catnip?
About 25-50% of cats do not respond to catnip at all. This lack of reaction is genetic. Cats inherit a gene that determines sensitivity to nepetalactone. If a cat does not have this gene, catnip will have no effect.
Other plants, such as silver vine and valerian root, can produce similar reactions in cats that do not respond to catnip. These alternatives contain different compounds that stimulate the feline sensory system in comparable ways.
Summary of What Catnip Does for Cats
Catnip contains nepetalactone, which triggers a sensory response in cats.
It causes temporary behavioral changes like playfulness, rolling, and purring.
The effects last about 5 to 15 minutes and are harmless.
Catnip is not a drug and does not cause addiction or harm.
Sensitivity to catnip is inherited, so not all cats respond.
Catnip can be used to encourage exercise, reduce stress, and provide mental stimulation.
