Why do cats roll on catnip?

Nepeta cataria, commonly known as catnip, is a species of flowering plant in the mint family native to Eurasia. It is widely naturalised in North America and is often grown in gardens. The plant is famous for its effect on cats, some of which become euphoric and playful when exposed to it. The reason for this response is not fully understood but is thought to be due to the presence of a chemical called nepetalactone in the plant's leaves and stems. When inhaled or ingested, nepetalactone binds to receptors in the cat's brain and triggers a response that can include rolling around, head shaking, drooling, and increased activity.

This response is not universal, and some cats may not be affected by catnip at all. However, for those that do react to it, catnip can provide a source of entertainment and relaxation. It can also be used to help train cats or to redirect unwanted behaviours.

In addition to its effects on cats, catnip has also been used for medicinal purposes by humans for centuries. The leaves and stems of the plant can be dried and made into tea, which is said to have a variety of benefits, including reducing stress, anxiety, and pain. Catnip can also be used as a culinary herb and is sometimes added to dishes like soups and stews.

As a safe and natural substance, catnip can provide both enjoyment and potential health benefits for cats and humans alike.
