Cats love catnip because it contains a compound called nepetalactone, which mimics feline natural pheromones and triggers a euphoric reaction in many cats. When cats smell or rub against catnip, this chemical binds to receptors in their nose and stimulates sensory neurons that send signals to areas of the brain responsible for play, hunting behavior, and emotions. This can make cats feel happy, playful, relaxed, or even hyperactive. The effect usually lasts about 10-15 minutes, after which cats become temporarily immune to catnip before they respond again. Not all cats respond to catnip, as sensitivity is inherited genetically and about 30% of cats do not react to it. Kittens and older cats are also less likely to respond.

Why Cats Like Catnip

• Nepetalactone mimics cat pheromones, causing pleasurable feelings.
• It stimulates brain regions related to emotions and predatory behavior.
• The response may range from playful and energetic to calm and relaxed.
• The unique reaction to catnip is due to genetics, affecting about two-thirds of cats.

How Catnip Affects Cats

• Causes behaviors such as rolling, rubbing, licking, jumping, or calm resting.
• Effects last about 10-15 minutes before wearing off.
• Temporary immunity prevents continuous effects until a break is taken.

Sensitivity Variation

• About 30% of cats do not respond due to genetic factors.
• Kittens younger than 3 months and senior cats show reduced responsiveness.

This combination of chemical interaction and genetic predisposition explains why cats love catnip and why their reactions vary.
