Catnip can live for about 2-3 years. Catnip refers to a type of perennial herb that can cause hallucinations in domestic cats and other felines. Its lifespan is about 2-3 years. Seed life is 1 year. Owners can sow catnip at home by themselves in spring and autumn. This can provide cats with fresh catnip leaves, but it is not recommended to feed them too much.

The effects of catnip on cats:

1. Catnip contains an ingredient called nepetalactone. Nepetalactone can cause nervous excitement in cats and cause hallucinations in cats.

2. Nepetalactone has a similar chemical structure to the substance secreted in the urine of estrous female cats. Male cats are more likely to be attracted to catnip than female cats.

3. Cats are very clean animals. They often lick their fur to keep it clean, and they also inhale some hair. Feeding some catnip in an appropriate amount can induce vomiting and help the cat vomit out hair.

4. Catnip can help cats calm down and relieve anxiety.

5. Catnip can increase the cat’s appetite.
