Questions & Answers

Q: Why do cats react to catnip?

Cats react to catnip because the compound nepetalactone in catnip mimics their natural pheromones. When this compound enters their nose, it triggers receptors in the brain and stimulates various areas, leading to the exhibited behaviors.

Q: Do all cats respond to catnip?

No, only about 50 to 70% of cats respond to catnip. The response to catnip is genetic, and scientists are still studying the specific gene and the brain reactions involved.

Q: Can kittens respond to catnip?

Generally, kittens do not respond to catnip until they reach sexual maturity at around six months old. This is because the brain receptors related to sexual response are not fully developed until that age.

Q: Why do big cats like lions and jaguars respond to catnip?

Big cats also respond to catnip because they have similar receptors and pheromones as domestic cats. However, other animals that do not share these pheromones or receptors are not affected by catnip.
