Catnip is an herb that belongs to the mint family and has a leafy green appearance. The organic compound in catnip, nepetalactone, is what gives cats their bizarre reactions. Heres what catnip does to cats:

• Mimics feline sex hormones: Catnip mimics feline sex hormones, so cats enjoying this substance will often display behaviors similar to a female cat in heat.

• Triggers happy receptors in the brain: When cats smell catnip, the herb targets feline "happy" receptors in the brain. 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.

• 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.

• Does not work on all cats: 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.

Its important to note that too much catnip can cause health problems in cats, such as vomiting, diarrhea, dizziness, or having trouble walking. Use just a little at a time, and you can always discuss the correct amount for your cat with your veterinarian.
