Fleas - if your
cat ever goes outdoors or comes in contact with animals that
do, you are probably familiar with these pests. Given the
right conditions, these tiny brownish insects can quickly
multiply and turn into a horrible infestation.
Many cats are allergic to fleas. For them, even a single
fleabite can trigger an acute response of dermatitis. For
cats that are not allergic, fleas can be just plain itchy
and irritating and also a source of tapeworm infection.
Kittens and sick cats are particularly vulnerable to fleas.
Left untreated, hordes of fleas have been known to cause
severe anemia in kittens and even death.
Know the Enemy
Fleas are small parasitic insects that feed on blood. There
are dozens of species of fleas, each adapted to a particular
host. The cat flea, Ctenocephalides felis, is the most
common type found in modern homes. The cat being their
preferred host, these fleas can also suck blood from humans,
dogs and other animals.
The flea's life-cycle consists of four stages. An adult
female flea lays several thousand eggs in her lifetime at a
rate of as many as 50 eggs a day. Eggs usually fall off the
host and then hatch into larvae.
Flea larvae prefer warm dark places, such as carpets and
soft furnishing, where they feed on flea droppings for
several days. Then they weave a small cocoon where they turn
into adult fleas.
The adult flea can lay dormant in its cocoon for many weeks,
waiting for a potential host to pass by. Triggered by heat,
movement and exhaled carbon dioxide, they come out of their
tiny silky shells and jump onto a passing animal or person.
It can be hard to tell whether or not your cat carries
fleas. These insects prefer to be in dark places and hide
deep inside the cat's coat. If you part your cat's hair, you
may just glimpse a flea as it scurries away into safety.
What you are more likely to notice are tiny black specs -
easier to spot on white cats. Wipe those black specs with a
wet tissue and note how they turn into small red dots. These
are in fact fleas feces made out of dry digested blood.
Treating the Problem
The fleas that are actually on the cat represent only a
fraction of the flea population present in the house, so
treatment must include the surroundings as well as the cat.
Regularly vacuum your house, giving particular attention to
carpets and upholstery. Because vibrations trigger fleas to
come out of their cocoons, they often come alive right after
vacuuming, while inside the vacuum bag. To prevent them from
returning to your home, make sure the bag is sealed and
quickly disposed of.
If you have a major flea infestation you should consult a
professional exterminator and treat the house with special
anti-flea products. Make sure you use only products that are
not toxic to cats.
As for treating your cat, there are several good products on
the market that are very safe and effective. Available from
your vet, these products can be used orally (Program) or
topically (Advantage or Frontline) to inhibit various stages
of the fleas' life cycle. There are other products in the
form of drops, sprays, collars and shampoos that can be used
to fight fleas. While cheaper and available over the
counter, many of these are either not safe enough or simply
ineffective.
