Why do cats like catnip?

Thinking of giving your cat catnip? Here’s a rundown of the benefits of catnip, how to give it safely, and what to watch for to keep your cat happy and healthy.

What is catnip?

Catnip, also known as Nepeta cataria, is a member of the mint family. This herb contains a compound called nepetalactone, which drives cats wild.

Why do cats like catnip?

Cats are drawn to catnip because nepetalactone mimics their natural pheromones. About two-thirds of cats respond to it (though estimates vary), often with behaviour that looks like pure euphoria. Some experts say catnip boosts a cat’s mood and encourages playfulness.

What does catnip do to cats?

Catnip can make cats hyperactive, playful, or completely relaxed. The effects last around 10-15 minutes before wearing off, and your cat will need a break before showing interest again. The benefits of catnip include encouraging play, providing mental stimulation, and helping reduce stress and anxiety. Cats sometimes roll around in catnip to release more scent and enhance the experience.

How do I give my cat catnip? 

You can sprinkle or spray catnip on your cat’s toys or scratching posts. Homemade catnip toys or catnip bubbles are also fun options. These are made with cat-safe ingredients and release the scent of catnip when they pop. Whichever form you choose, start with small amounts, as a little goes a long way.

You might want to give your cat catnip in various situations. For example, if your cat is feeling stressed before a vet visit, a sprinkle of catnip on their favourite toy can help calm their nerves and make them feel more at ease. If you have guests over or are moving to a new home, introducing catnip can encourage your cat to play and explore, easing any anxiety they might have.

Just remember to supervise your cat while they enjoy catnip to ensure they have a safe and enjoyable experience.

Is catnip bad for cats?

No, catnip isn’t harmful. However, too much can cause mild side effects like vomiting or diarrhoea. While cats can’t overdose on catnip, frequent exposure might make them less responsive over time.

Can cats be allergic to catnip? 

Allergies to catnip are rare, but some cats may experience mild reactions like sneezing or a runny nose.

Should kittens have catnip? 

Kittens under three months usually won’t react to catnip. It’s safe for them after that, but it’s best to wait until they’re a bit older before introducing it.

Does catnip make cats high? 

Yes, in a way! Catnip can trigger a temporary "high" where cats become playful, energetic, or relaxed. The sensation is harmless and enjoyable for most cats.

Can cats eat catnip?

Sniffing catnip is fine, but eating too much can upset a cat’s stomach. Overeating may cause vomiting or diarrhoea, so moderation is important.

Can a pregnant cat have catnip? 

It’s best to avoid giving catnip to pregnant cats, as it may overstimulate them.

How often can I give my cat catnip?

It’s safe to give your cat catnip a couple of times a week. While the effects wear off after about 15 minutes, your cat needs time to “reset” before getting excited again.

Can a cat have too much catnip?

Yes, overexposure can reduce a cat’s sensitivity to catnip over time. Stick to small amounts and space out the sessions to keep it exciting.

Where can I buy catnip? 

You can buy catnip at most pet stores or grow it at home. It comes in many forms, including sprays, powders, and pre-stuffed toys. Get creative with homemade catnip toys or try growing Nepeta cataria.

What does catnip do for dogs? 

Interestingly, catnip doesn’t affect dogs the way it does cats. While dogs can safely eat it, it typically has a calming effect rather than causing excitement.
