Catnip (Nepeta cataria) is a perennial herb in the mint family. Originally from Europe, it’s now found across the world, including here in Australia. While it looks like an ordinary plant, catnip has a reputation for sending cats into what’s often described as feline euphoria.
Around two-thirds of cats inherit the sensitivity to catnip, while others won’t react at all. So, if your cat isn’t fussed, don’t worry – it’s perfectly normal. Some cats are into it. Some just… aren’t.
Why do cats like catnip?
The magic comes from a chemical in catnip called nepetalactone. When cats smell the bruised leaves or stems, it activates special receptors in their nose. That’s when the fun begins.
What does catnip do to cats?
Reactions vary, but you might see your cat:
- Rolling on the floor
- Pawing, chewing, or licking the herb
- Leaping about with sudden bursts of energy
- Purring or meowing more than usual
- Even drooling a little
Some cats get playful and silly, but others might growl or become vocal. It’s all part of the harmless, short-lived response.
How long does the effect of catnip last?
The “high” only lasts a few minutes before your cat loses interest. Then just like that, it’s over.
After about two hours, their brain resets and they’ll usually be ready to go again.
Kittens and senior cats are less likely to react, while big cats like lions and tigers can also feel the effects. Importantly, catnip isn’t addictive or “drug-like”. It’s simply an emotional release that’s safe and healthy for your cat.
Is catnip safe for kittens?
Yes, catnip is safe for kittens, but most won’t respond until they’re around 6 months old. Their sensitivity develops as they mature, so don’t worry if your little one shows no reaction. You’re not missing out on the fun – you just need a bit of patience.
If you’d like to introduce it early, you can still offer catnip toys for play, but expect the full “catnip effect” later in their growth.
How often can I give my cat catnip?
Catnip is best enjoyed in moderation. Most cats will happily play with catnip a few times a week, but if it’s offered too often, the effect may wear off and they’ll lose interest.
Think of it like a special treat. To keep it exciting, rotate when and how you give it – sprinkling dried catnip on a scratching post one day, offering a catnip toy later in the week. A little mystery keeps it fun.
Store dried catnip in the freezer in an airtight container. It helps preserve its potency for months, so your cat continues to experience the same strong reaction.
Can dogs have catnip?
Interestingly, catnip doesn’t affect dogs the same way it does cats. Dogs don’t experience that playful euphoria, but the herb can still have some benefits.
In small amounts, catnip may have a calming effect on dogs, sometimes used to ease mild anxiety or help them settle before bedtime. It’s also thought to support digestion in some cases. That said, it’s not a common treat for dogs, and giving too much can cause an upset stomach, so always offer it in moderation and check with your vet if you’re unsure.
Is catnip legal in Australia?
Yes, catnip is legal in Australia. You can buy it freely from pet stores, online retailers and even grow it in your own backyard.
Where can I find catnip?
You’ll find catnip in almost every pet store and vet clinic. It comes in different forms to suit your cat’s play style, including:
- Dried catnip (sprinkle onto scratchers or toys)
- Sprays (great for refreshing scratching posts)
- Catnip-infused toys
- Treats for an extra bit of fun
Catnip can even be used as a handy training tool. Sprinkling it on a scratching post or cardboard pad, for example, can help redirect your cat’s claws away from the couch and onto a “legal” scratching spot.
