Catnip is a perennial mint herb known for its powerful effect on many cats. It's a common enrichment item for Canadian cat owners.

What catnip is

Catnip (Nepeta cataria) is a strong-scented perennial herb in the mint family, valued for its aromatic leaves and pale flowers. It's widely known for attracting felines and is often grown in Canadian gardens.

Why cats respond

The compound nepetalactone triggers behaviours like sniffing, rubbing, rolling, and playfulness. The response typically lasts 5–15 minutes before olfactory fatigue sets in.

Uses and safety around cats

Catnip is commonly sold as a pet product and garden herb in Canada. It's generally safe in moderation, though too much may cause mild stomach upset. Humans can also use it in small amounts, such as in herbal tea.

In short

  • Catnip is a mint-family herb, not a synthetic product.
  • Its cat-attracting effect is mainly due to nepetalactone.
  • Not all cats respond to catnip; sensitivity varies.
  • The behavioural response usually lasts only a few minutes.
