Catnip, in large enough quantities, will also work as an attractant for large cats like lions and tigers. Europeans in the 1400s regularly drank teas made from catnip, with the herb earning a medicinal application for treatment of colic and flatulence.
Catnip is a natural herb of the mint family which acts as a hallucinogen. No wonder cats go nuts! Don't worry though, it is nonaddictive. Although, it will lose its effectiveness on your cat if used too frequently so only give it as an occasional treat. Some cats don't seem to display any interest in catnip; however, most cats love it! You can purchase catnip at your pet store. The best form to provide your cats with catnip is to simply buy fresh catnip. When giving your cat fresh catnip squeeze it between your fingers (this helps release the oils in the herb) and place a little bit of it on the floor.
