Cats and catnip

If you have a cat, there's a good chance you've witnessed firsthand one of the great feline mysteries known as the "catnip response." When presented with the leaves of Nepatia cataria, most domestic cats will engage in a variety of behaviors — including chin rubbing, rhythmic kicking with their back feet, sniffing, licking and chewing the plant, and rolling onto their sides. The reaction can last from about 5 to 15 minutes, after which point the cat will lose interest and walk away. For the next couple of hours, she'll be immune to the herb's effects – but don't be surprised when she returns to repeat the cycle.

Catnip and its mysterious effects

What gives? Even scientists don't fully understand why felines respond to catnip the way they do. They do know, however, that this inherited reaction is induced by a chemical in the herb called transnepetalactone. Kittens are largely unaffected by catnip, and even those who are genetically predisposed won't feel a real thrill until they're at least six to eight weeks of age. Older cats seem to be less sensitive to the herb as well. But best of all, this terrific treat is not toxic and its effects will not harm your pet.

Using catnip

If your kitty goes kooky for catnip, you're in luck — there's a wide variety of catnip products out there. Catnip mice and other catnip-stuffed toys are classic feline favorites, and can be a fun and effective part of a program to keep more sedentary pets active and exercised. Do take care to avoid toys with bells or other small parts that Fluffy could accidentally swallow or choke on.

You can also simply drop a few tablespoons into a dish, or stuff some loose catnip into a small sock, tie it tightly and offer it to your kitty during playtime. Note that stepping on the sock will help release the herb's active ingredients. Loose catnip can be rubbed on scratching posts to attract an animal's interest – and is particularly effective if your kitty tends to scratch in inappropriate places. Keep in mind that the herb does go stale after a few months, so you'll want to replace any toys or loose herbs that have lost their zip.

Catnip effects can be therapeutic

Catnip is also gaining recognition for its usefulness in comforting cats who have undergone surgery. Veterinary offices can lessen anxiety in the recovery room by sprinkling some fresh catnip on the floor two or three times a day. This herbal therapy can be continued when the feline patient returns home.

Catnip can also come in handy should your family move to a new home, an event that's quite stressful for pets. Bring the cat with you to your new house before the furniture arrives. Lay a trail of catnip from one room to the next, and let your pet follow it as she explores.

Catnip is grown in various climates and altitudes. However, high elevations produce the most potent catnip. Something to keep in mind when you buy this feline treat.
