Catnip has a calming effect on cats and is often used to treat feline anxiety and excitement. When cats smell catnip, they often become calm and sleepy, and some cats even become aroused and exhibit mating behaviors. Catnip can also be used to stimulate cat behavior, such as playing and exploring.

Catnip is known to have cat-like properties, such as stimulating the olfactory system and causing cats to become excited. It is believed that catnip works by mimicking the pheromones that cats produce to communicate with each other.
