What is catnip, and why do cats go wild for it?

Catnip, scientifically known as Nepeta cataria, is a member of the mint family. It’s a hardy, fragrant herb native to Europe, Asia and North America. Cats love its strong minty scent, giving them a natural high. The key ingredient in catnip is a compound called nepetalactone, found in the plant's leaves, stems, and seeds.

Why do cats love catnip?

Catnip, or Catmint as it is also called, triggers a chemical response in the brain that mimics feline pheromones. For about 50–75% of cats (not all cats are affected), this means:

Excitement: They may roll, rub, purr, jump, or even dart around the room.

Relaxation: After the initial high, many cats mellow out and may take a catnap.

Playfulness: Catnip can encourage exercise and mental stimulation, especially in indoor cats.

Interestingly, the reaction is hereditary. If a cat doesn’t have the genetic trait to respond to nepetalactone, catnip won’t affect them at all.
Kittens and senior cats also tend to show less interest.

Is Catnip safe?

Catnip is completely safe and non-addictive for cats. Reactions typically last 10–15 minutes, and then cats become temporarily immune to its effects for a while. However, moderation is key, eating too much catnip might lead to a mild tummy upset.

Catnip can also be brewed into a calming tea for humans (though it won’t have the same effect as it does on cats).

You can grow catnip at home on a sunny window or garden. Just be prepared for some enthusiastic feline visitors!
