Woody catnip is an all-natural plant. It contains components such as actinidin, which have specific effects on kittens. Therefore, these substances can be harmful to cats in several ways, including:

1. High doses of Polygonum hydropiper may cause addiction in kittens.
Second, cats often chew on catnip with their teeth. If they ingest too much powder at this time, it can also put a burden on their liver.
Third, do not let your cat swallow the catnip, as this will cause it to get stuck in the kitten's mouth.
Actually, catnip is similar to cat grass and catnip; it can make cats feel happy and help them expel hairballs, as well as relieve their tension and anxiety.
