Catnip is the common name for a perennial herb of the mint family. The active ingredient in catnip is called nepetalactone which can trigger strange behaviors in cats. Cats don’t actually eat catnip and respond to its taste, but rather, are reacting to the smell. It can be either in a dry or fresh form.
It is made up of a nucleus (solid, frozen ice, gas and dust), a gaseous coma (water vapor, CO2, and other gases) and a long tail (made of dust and ionized gases). The tail develops when the comet is near the Sun. Its long ion tail of always points away from the sun, because of the force of the solar wind.
