Catnip is an herb that belongs to the mint family and has a leafy green appearance. The essential oil in catnip is called nepetalactone, which stimulates cats in ways that are similar to how cannabis affects humans. When cats smell catnip, it can cause behavioral changes as the scent is carried to their brains from pathways in their nose and mouth. The most intense catnip experience starts with the nose, and one whiff of the stuff can make a cat go nuts. The effects of catnip can vary from cat to cat, but most cats react to it by rolling, flipping, rubbing, and eventually zoning out. They may meow or growl at the same time. Other cats become hyperactive or downright aggressive, especially if you approach them.

Some cats enjoy catnip because it mimics feline sex hormones, so they display behaviors similar to a female cat in heat. For cats that have a positive experience with catnip, it can help reduce anxiety and even relieve pain. Some veterinarians have recommended using catnip to help with separation anxiety if your cat will be home alone for an extended period of time. Catnip can also be helpful with behavioral issues. For instance, if your cat is scratching the furniture but not going near the scratching posts and mats you’ve set out, sprinkle a little catnip on them. That should get their attention.

It is important to note that not all cats react to catnip, and sensitivity to this herb is hereditary. An estimated 50% of cats have no reaction. Additionally, too much catnip can cause health problems in cats, such as vomiting, diarrhea, dizziness, or having trouble walking. It is important to use just a little at a time, and you can always discuss the correct amount for your cat with your veterinarian.
