What Is Catnip? A Guide to Your Cat’s Favorite Treat
Dilated pupils. High-powered zoomies. Complete, utter bliss. This can only mean one thing: Your cat’s been given catnip.
This aromatic herb sends our feline friends into a fun-filled frenzy. But what is catnip, exactly?
We spoke with veterinarians to learn more about this green plant and why our cats love it so much.
What Is Catnip?
Catnip, or Nepeta cataria, is a perennial plant in the mint family. Native to central Europe, Asia, and North Africa, it’s sometimes called catnep, catsworth, or field balm. The name “catnip” likely comes from “nip”—a small quantity of something intoxicating—reflecting how powerfully it affects cats.
The primary compound responsible for its effects is nepetalactone, an organic chemical found in the plant’s leaves and stems. When released—especially when the leaves are crushed—it triggers a distinctive response in susceptible cats.
Humans have used catnip for centuries too: dried leaves appear in herbal teas, calming bath products, and natural insect repellents. Historically, catnip flowers were also used to soothe coughs, sore throats, and fevers.
What Does Catnip Do to Cats?
Catnip can make even the tamest feline go wild—but what’s really happening inside your cat?
“When cats smell catnip, nepetalactone binds to receptors in their nasal tissue,” explains Dr. Sabrina Kong, veterinary consultant at FurPetVo. “This stimulates sensory neurons that trigger a temporary, euphoric response—think of it as a feline ‘happy button.’”
About 50–70% of cats inherit a genetic sensitivity to catnip, which explains why some cats leap and roll while others seem completely unimpressed. The reaction is instinctive—and echoes behaviors seen in wild ancestors who used similar plant compounds for communication and play.
How your cat responds depends on how they interact with it:
- When sniffing catnip: You may see rolling, rubbing, purring, sprinting, or playful pouncing.
- When eating catnip: Effects tend to be mellow and sedative—often leading to relaxed napping.
The high lasts roughly 15 minutes. If your cat doesn’t respond, they may still be too young (most kittens don’t react until around 6 months old) or simply among the roughly one-third of cats without the genetic sensitivity, notes Dr. Brad Krohn of The Cat Behavior Clinic in Seattle.
Why Do Cats Like Catnip?
For cats who respond, catnip delivers a uniquely intoxicating experience—one rooted in biology, not just fun.
“Nepetalactone mimics natural feline pheromones, especially those linked to mating and social behaviors,” says Dr. Kong. “It tricks the brain into a brief, safe state of excitement—or deep relaxation—depending on the cat.”
You might notice any of these behaviors:
- Rolling and rubbing against surfaces
- Purring loudly or vocalizing excitedly
- Leaping, chasing imaginary prey, or mimicking hunting
- Kneading paws or grooming excessively
- Drooling or displaying gentle mating behaviors
“A cat might sprint around the room like a whirlwind, then collapse into a blissful nap,” Dr. Kong adds. “Rarely, overstimulation leads to mild hissing or swatting—but these reactions are short-lived and harmless.”
Dr. Krohn recommends catnip as a powerful tool for environmental enrichment. “It’s like their brain throwing a temporary party—to break up the monotony of indoor life,” he says. “It helps relieve stress by encouraging movement and satisfying their innate prey drive.”
Because catnip triggers feel-good neurochemicals, cats often enter their most fearless, playful state—building confidence over time. Shy or anxious cats, in particular, may benefit from regular, supervised exposure.
“Experiencing joyful play and improved mood can truly help a timid cat come out of their shell—or out from under the bed,” Dr. Krohn notes.
Types of Catnip
Not all catnip is created equal. Depending on your cat’s personality and needs, different formats offer unique benefits—from sparking energy to encouraging calm.
Dr. Kong outlines the most common, vet-approved types:
- Dried leaf catnip: The gold standard—potent, versatile, and ideal for stuffing toys or sprinkling on scratching posts. For cats who don’t respond to plain catnip, try a blend with silvervine (a stronger alternative).
- Catnip sprays: Milder and perfect for timid cats or targeted use—like refreshing a favorite bed, carrier, or scratching post. Great for redirecting unwanted scratching behavior away from furniture.
- Fresh catnip plants and treats: Yes—cats can safely eat catnip! Growing your own plant gives you control over freshness and quality. Ready-to-serve treats (like dental chews or soft bites) combine flavor, function, and fun.
- Catnip-infused toys: Pre-filled plush toys or interactive puzzles require zero prep—and keep playtime engaging with minimal effort.
When choosing products, Dr. Kong advises selecting options with no synthetic fillers, artificial fragrances, or alcohol-based essential oils.
“Concentrated catnip oils often contain irritants that can upset a cat’s skin or digestive tract,” she warns. “Pure, natural dried catnip is safer—and just as effective.”
How to Give Catnip to Cats
Ready to introduce catnip to your feline friend? Here are simple, effective ways to offer it:
- Sprinkle dried leaf catnip onto existing toys—or stuff refillable plush toys with it.
- Add a pinch to meals or mix it into puzzle feeders to encourage mental stimulation and slow eating.
- Lightly mist cat beds, carriers, cat trees, or scratching posts with catnip spray to refresh interest and comfort.
Start with small amounts and observe your cat’s response. Use catnip two to three times per week to keep reactions strong—overuse can dull sensitivity over time.
Is Catnip Bad for Cats?
No—catnip is non-toxic, non-addictive, and completely safe for healthy cats when used responsibly.
While rare, excessive ingestion may cause mild stomach upset—so always offer it in moderation. Kittens under six months and senior cats with certain medical conditions should be introduced gradually and monitored closely.
As Dr. Kong puts it: “Catnip isn’t medicine—but it *is* joy, movement, and connection in plant form. When used thoughtfully, it’s one of the simplest, safest ways to support your cat’s emotional and physical well-being.”
