Catnip is like magic for many cats—rolling, purring, and zooming around in pure bliss. But if you have a kitten, you might wonder: How old do cats need to be before they can enjoy catnip safely?
The short answer: Most kittens won’t respond to catnip until they’re at least 6 months old. However, some cats may take longer (or never react at all!).
In this guide, we’ll cover:
✔ When cats can safely have catnip
✔ Why kittens don’t react to it early on
✔ How catnip affects cats (and why some ignore it)
✔ Safe ways to introduce catnip
What Is Catnip & How Does It Work?
Catnip (Nepeta cataria) is a herb from the mint family that contains nepetalactone, a compound that triggers a euphoric response in about 50-70% of cats.
When cats smell or ingest catnip, they may:
- Rub, roll, and drool
- Become hyperactive (the “zoomies”)
- Purr or meow excessively
- Zone out in a relaxed state
These effects last 10-15 minutes, followed by a temporary “refractory period” where they won’t react again for a few hours.
When Can Kittens Have Catnip?
The Safe Age: 6+ Months
Most kittens won’t respond to catnip until they reach sexual maturity (around 6 months old). This is because:
- Their olfactory system (sense of smell) isn’t fully developed.
- They lack the genetic sensitivity to nepetalactone early on.
⚠️ Can kittens under 6 months have catnip?
While it’s not harmful, it’s usually pointless—they likely won’t react. Some vets recommend waiting until 8-12 months for a stronger response.

Why Doesn’t My Cat Like Catnip?
Not all cats are affected! About 30-50% lack the gene that makes them sensitive to nepetalactone. Other reasons include:
- Too young (under 6 months)
- Overexposure (cats can become desensitized)
- Alternative preferences (some cats prefer silver vine or valerian root)
How to Safely Introduce Catnip
- Start Small – Use a pinch of dried catnip or a light spray.
- Observe Their Reaction – Some cats get hyper, others relax.
- Limit Use – Offer catnip once a week to prevent desensitization.
- Try Different Forms – Fresh, dried, sprays, or catnip-filled toys.
💡 Pro Tip: If your cat doesn’t react to catnip, try silver vine (a stronger alternative).
