Why Do Cats Eat Grass?

8. The Catnip Question

Catnip is famous for its feline appeal, and luckily it is generally safe for cats to be around. Researchers believe that the main reason cats love this plant is its high nepetalactone content, which mimics certain natural pheromones that cats emit. However, the appeal does appear to be genetic. Studies have shown that about 30% of cats have no interest in this plant, and the trait seems to run in families.

Although catnip is generally safe, you might want to keep a close eye on your cat if you notice he has a tendency to eat large amounts of catnip. It can sometimes cause an upset stomach, which may lead to unpleasant messes.
