Catnip is a perennial herb that drives many house cats wild
with delight. It was probably first noticed as an attractant when big
cats
swarmed around withered or bruised plants growing in the wild. A full response to catnip involves four separate actions,
usually in this order:
1. Sniffing
2. Licking and chewing with head shaking
3. Chin and cheek rubbing
4. Head-over rolling and body rubbing.
The full circle usually lasts under fifteen minutes. Some
cats will also vocalize after the head-over rolling, presumably a response to hallucinations. Although
the cats exposed to catnip mimic their behavior when in heat, catnip does not increase sexual interest or activity and doesn’t seem to affect
cats in heat
more perceptibly.
Scientists know quite a bit about how domestic
cats react to catnip Most cats do not begin responding to the plant until they are six to
eight weeks of age, and some may not respond until they are three months of age. All of the research provided by the Cornell Feline Health Center indicates that cats’ reaction to catnip is independent of sex or neutering status. Susceptibility is inherited as an autosomal dominant trait-about a third
of domestic cats have no reaction to catnip.
Two-legged mammals have not been immune to the charms of
catnip. Veterinarian Jeff Grognet cites the historical use of catnip by humans:
the versatile herb was used to make tea, juice, tincture, poultice, and
infusions. Catnip was also smoked and chewed for its reputed therapeutic,
Hallucinogenic, or euphoria-inducing properties.
Scientists, like our reader, have also been curious about
the effect of catnip on other cats, and other types of animals, Dr. N. B. Todd’s
conclusion was clear” Although a few individual animals of almost every type
reacted in some way to catnip, cats responded most often and most intensely.
Out of sixteen lions tested, fourteen had full household
cat-type responses. Almost half of twenty-three tigers tested had no response
at all, but many had incomplete responses: Some sniffed: fewer licked: only a
couple chin-rubbed” and none exhibited head-over rolling. But young tigers had
violently strong reactions to catnip. Most leopards, Jaguars, and snow leopards
had strong, full-cycle reactions to catnip. We know that bobcats and lynx love
catnip, for the herb is sold commercially to lure these
cats for trapping
purposes.
Non-cats, such as civets and mongooses, were mostly
indifferent to catnip, although a few exhibited sniffing reaction. An earlier
study that predates Todd’s concluded that
dogs,
rabbits,
mice, rats,
guinea
pigs, and fowls were indifferent to a powdered form of catnip that seduced
domestic cats. Yet many
dog owners report that their pets respond to catnip.
For some anecdotal evidence, we contacted several of the
largest American zoos to see if they exposed their big
cats to catnip. We found
cat keepers almost as curious about catnip as the
cats themselves.
We spoke to one cat keeper who fed
jaguars catnip
directly. “ They like it,” he said. “ They get goofy.” But the same keeper
reported that a snow leopard wasn’t interest. Another keeper reported the tigers
responded “to some extent.”
Rick Barongi, director of the Children’s Zoo at the San
Diego Zoo, reports that although most pet owners usually spray catnip scent on a
favorite toy of their cat, zoo keepers cannot. A jaguar or
lion will simply rip
apart and then eat the toy, so instead they spray a piece of wood or a log that
a big cat can claw or scratch. Barongi shares the belief that all cats respond
to catnip to some extent but that younger
cats respond more than older
cats, and
that all cats react more on first exposure to catnip than in subsequent
encounters.
After a thrill or two with catnip, the San Diego Zoo
keepers have found that big cats are more entertained in the long run by scratch
posts, boomer balls. Larger cages, or-most expensive, but most satisfying of
all-the pleasure of the company of a cage mate.
