Catnip shouldn't be inhaled for too long. Although catnip is not toxic to cats and won't make them addicted, excessive inhalation can cause cats to develop immunity, reducing its effectiveness.
Additionally, excessive catnip inhalation can negatively impact a cat's respiratory system, potentially causing breathing difficulties. This is because cats tend to relax after inhaling catnip, which lowers their immunity, and repeated exposure may lead to respiratory infections.
