Catnip: What It Does (and Doesn't Do) to Your Cat

Catnip (Nepeta cataria) Effects on Cats

• Active compound: Nepetalactone (volatile oil) binds to olfactory receptors → triggers behavioral response.
• Typical reaction (50–70% of cats): Sniffing → rolling, rubbing, head shaking, vocalizing, hyperactivity, then sedation. Lasts 5–15 min; refractory period ~1–2 hrs.
• Genetic: Autosomal dominant trait; kittens < 3–6 mo and ~30% adults non-responsive.
• Route: Olfactory only; ingestion produces mild sedation, not euphoria.

What Catnip Does NOT Do

• No psychoactive effect on humans (different receptor biology).
• Not addictive; no withdrawal.
• Not harmful in normal use; rare GI upset if large amounts eaten.
• Does not affect dogs, rodents, or other pets similarly.

Safe Use Tips

• Dried herb, spray, or infused toys – all effective.
• Limit to 1–2×/week to maintain responsiveness.
• Store in airtight container in freezer to preserve potency.
• Supervise multi-cat households (can trigger aggression in rare cases).

Alternatives for Non-Responders

• Silver vine (Actinidia polygama) – 80% response rate.
• Valerian root, Tatarian honeysuckle, cat thyme.

Catnip is a safe, enriching olfactory stimulant for responsive cats—purely feline fun.
