Catnip is an herb that belongs to the mint family and has a leafy green appearance. It contains an essential oil called nepetalactone, which can turn even the laziest cat into a crazy furball if the cat has inherited the sensitivity to its effects. Heres what catnip does to cats, according to the search results:

• Behavioral changes: When cats smell catnip, they experience behavioral changes that can mimic a female cat going into heat, although male cats can also be affected by catnip. The scent of nepetalactone oil, which is found in the leaves of catnip, is carried to their brains from pathways in their nose and mouth, causing behavioral changes.

• Different reactions: Most cats react to catnip 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 while they are playing with catnip. Some cats may even become affectionate and relaxed. When eaten, catnip tends to have the opposite effect and can cause cats to mellow out.

• Hereditary sensitivity: Sensitivity to catnip is hereditary, and an estimated 50% of cats have no reaction. The trait doesnt emerge until a cat is between three and six months old; until then, a kitten will not have a response.

• Reduces anxiety and relieves pain: 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.

• Digestive upset: It is important to prevent your cat from ingesting large amounts of catnip, as this can cause digestive upset. Too much catnip can cause dizziness, diarrhea, trouble walking, or vomiting in your pet, so it is best to speak with your veterinarian about the correct dosage for your feline friend.

In conclusion, catnip can cause different reactions in cats, including behavioral changes, relaxation, and even aggression. Sensitivity to catnip is hereditary, and it can help reduce anxiety and relieve pain in cats. However, it is important to control how much your pet is exposed to it, as too much catnip can cause digestive upset.
