Ticks
and fleas
Ticks are small spider-like
acarids and fleas are insects, but these two tiny
creatures have at least one thing in common—they are
both parasites that feed on your cat’s blood and can
cause a lot of discomfort and more serious health
problems.
Flea bites may go unnoticed on some pets, cause slight
irritation in others and produce extensive itching, red
lesions, hair loss and even ulcers in those animals with
flea allergy dermatitis, which is the result of extreme
sensitivity to flea saliva. Severe flea infestations can
cause anemia, especially in kittens. Fleas can also
transmit several diseases, as well as tapeworm. Ticks
are “vectors” or carriers of a number of diseases,
including Lyme disease and Rocky Mountain spotted fever
which can sometimes be transmitted to humans.
About
fleas…
Adult fleas are wingless insects,
generally smaller than a sesame seed, who feed on the blood
of animals. Their proportionately enlarged back pair of legs
gives them an extraordinary jumping ability. Hanging on to
your pet’s fur with their claws, their needle-like mouth
parts bite through the skin to suck up blood—in quantities
of up to 15 times their body weight daily in the case of
female cat fleas.

If one flea finds your cat an attractive food source, you
can be sure that other fleas will, too! They mate, with
females laying 30–50 eggs per day. These eggs will drop to
the ground within 8 hours and, as soon as 2 days later flea
larvae will hatch and hide in dark places on the ground, on
carpets or in upholstery. After about a week of feeding on
adult flea droppings, crumbs, flakes of skin, etc., the
larvae spin cocoons to become pupae. The pupae can remain in
this stage for very long periods of time. As early as a week
later, the pupae develop into adult fleas and emerge from
their cocoons when they sense that a cat or other animal
host, is near. The cycle—which can take as little as 12 days
or as long as 180 days—can then begin again.
And ticks...
Ticks are wingless creatures
that live exclusively on the blood of animals for three of
the four stages of their life cycle. They are equipped with
an apparatus called Haller’s organ which senses heat, carbon
dioxide and other stimuli to allow the ticks to locate the
presence of an animal food source. Once found, they crawl on
and embed their mouth parts into the animal’s skin and
proceed to suck up its blood.
You
should inspect your pet regularly for ticks, especially if
they have been outside in areas where there are woods or
tall grasses. A thorough combing within 4 to 6 hours of
exposure to such environments can help prevent ticks from
attaching themselves to feast on your pet. Should you find a
tick, it should be removed immediately, as the longer it is
attached to its host, the greater the chance for disease. Do
not touch the tick. Wear gloves and use tweezers to
carefully grasp the exposed section of the tick’s body near
your pet’s skin. Gently pull until the tick lets go. To
dispose of the tick, wrap it in several tissues and flush it
down the toilet. Do not crush, burn or suffocate it, as any
one of those actions may spread infectious bacteria.
Controlling fleas and ticks
The best way
to control flea problems is to prevent them from happening
in the first place. Fortunately, developments in veterinary
parasite control in recent years have made the twofold goal
of eliminating fleas on pets and preventing further
infestations much easier to achieve. Available for both cats
and dogs, new insecticides and insect growth regulators in
easy-to-use topical or oral forms not only eliminate any
existing fleas, but also work long-term to prevent future
infestations. This is accomplished either by killing the
parasites before they can reproduce or by preventing their
eggs from developing into normal adult fleas. Consult your
veterinarian for advice about the proper product for your
pet. Furthermore, thorough daily vacuuming of high-traffic
areas and frequent washing of your pet’s bedding will also
go a long way in reducing the flea population in your home.
Some of the same types of topical or oral products used to
control flea infestation are also effective against ticks.
Such treatments should be combined with daily examinations
and tick removal for those pets, especially cats, who are
frequently outdoors in areas with high tick populations. Ask
your veterinarian for information about the situation in
your locality. Clearing brush and long grasses and removing
leaves, grass clippings and other organic debris will also
help reduce the presence of ticks by disturbing their
natural outdoor habitats.
When a parasite picks
your pet for a meal
If, despite your best efforts at
control, you find that fleas or ticks have crawled (or
jumped) on board your pet, you will have to use a product
that will kill and/or repel the parasites. These include
once-a-month topical treatments, or more regular use of
sprays, powders, dips, shampoos, collars and, to combat
fleas, oral or injectable medication. Once again, you should
ask your veterinarian for advice about what the most
appropriate product is for your pet . And remember, it is
perfectly normal to see live fleas or ticks on a pet
immediately after a topical treatment, spray, shampoo,
collar, etc. is applied. Many believe that this means the
product is not working, but the fleas or ticks have to fully
absorb the product before they will be affected, which may
take from a few hours to a few days.
Facts about fleas
Worldwide, there are about
3,000 different types of fleas, but the cat flea
(Ctenocephalides felis)
is the most common to be found on cats and dogs.
Adult fleas can jump 600 times an hour. Each jump, in
terms of the flea’s size, is the equivalent of a person
clearing a 50-story building.
The record jump for a flea is 13 inches.
In just 30 days, 25 adult female fleas can multiply to
250,000 fleas.
Tips
about ticks
A female
tick can lay up to 3,000 eggs.
Except for eggs, ticks need a blood meal to progress to
each stage of their life cycle.
Some ticks can live for more than a year without a meal.
In very rare cases, toxins secreted by ticks can cause
pet paralysis.
