What Is Catnip and Why Do Cats Love It?

Catnip, also known as Nepeta cataria, is a plant from the mint family that contains a natural chemical called nepetalactone. This is the magical compound responsible for the funny behaviors we see in cats. When cats smell nepetalactone, it triggers receptors in their nose that send signals straight to their brain—specifically the part that controls emotions and behaviors.

Most cats respond with pure excitement. They rub their face on the source, roll around, jump, meow, and sometimes enter full-on zoomie mode. This reaction usually lasts for about 10–15 minutes before the effect wears off.

Not all cats react to catnip, and that’s completely normal. Catnip sensitivity is genetic, meaning some cats simply don’t have the receptors to enjoy it. About 60–70% of cats respond to catnip, while the rest may ignore it entirely.

How Catnip Affects Your Cat’s Brain

So, why do cats like catnip on a deeper level? It all comes down to how nepetalactone interacts with their brain.

When cats inhale the scent, it stimulates the olfactory system, which then activates the amygdala and hypothalamus—the brain regions responsible for emotions and instinctive behaviors. This creates a temporary state that resembles feline “happy excitement.”

Cats may show behaviors like:

• Rolling and rubbing their face
• Purring or chirping
• Zooming around the room
• Drooling
• Sitting in a relaxed daze
• Kicking toys with their back legs

It’s important to note that catnip isn’t harmful or addictive. The effects naturally fade, and cats cannot overdose through normal play. After the reaction stops, cats usually enter a short “reset” period where they won’t respond again temporarily.

Different Forms of Catnip and How to Use Them Safely

Catnip isn’t just limited to the dried leaves you sprinkle on scratching posts. There are various forms you can try depending on your cat’s personality and play preferences.

1. Dried Catnip

This is the most common type and can be sprinkled on:

• Toys
• Scratching posts
• Cat trees
• Cardboard scratchers

Start with a small amount—a little goes a long way.

2. Catnip Toys

These toys are stuffed with dried catnip or infused with the scent. They’re great for encouraging active play.

3. Catnip Spray

A super convenient option. Use it to refresh old toys or make new spaces more exciting.

4. Catnip Bubbles

A fun twist that many playful cats love. Great for interactive bonding.

Safety Tips

• Don’t give catnip more than once a day. Overexposure reduces sensitivity.
• Store catnip in an airtight container to maintain freshness.
• If your cat becomes overstimulated, give them space to calm down.

Why Some Cats Don’t React to Catnip

If you’re wondering, “Why does my cat ignore catnip completely?”—you’re not alone. Not all cats respond to catnip, and that’s totally normal.

Reasons may include:

Genetics

Some cats simply don’t have the gene required to respond. This is true for about 30–40% of cats.

Age

Kittens don’t react to catnip until they’re around 6 months old.

Different Preferences

Some cats prefer silvervine or valerian root, which have a stronger effect for non-catnip responders.

If your cat isn’t into catnip, try introducing these alternatives—you might be surprised by their reaction!
