If a kitten sucks catnip, it will go crazy, be highly relaxed, and have a dizzy state. If a kitten sucks a large amount of catnip, it will cause the kitten to go crazy continuously and become physically uncomfortable. In this case, the owner must ask Kittens should drink more water to help their bodies metabolize catnip. Catnip can make cats feel happy, but kittens under 6 months old should not smoke it.
