The most common method of infection is
through the uterus of the mother cat. Scientists have learned
that the dormant, microscopic larvae present in the mother become
active when she's about 42 days pregnant. The larvae migrate from
the mother's tissues to those of the kittens while they are still in
the uterus. Another method of infection is through mother's milk.
Signs of Roundworms In Cats
Kittens infected with roundworm are often thin and suffer from
diarrhea. They sometimes look pot bellied. Often the most
obvious sign is presence of the worms in the kitten's stool or vomit.
Treatment For Roundworm In Cats
Many over the counter products are available, including Drontal and
Drontal Plus, Heartgard Plus, Panacur, and Revolution. Sometimes
two and even three treatments may be necessary to completely solve the
problem.
Hookworms
Hookworms are small parasites (less than half an inch long) that
affect cats of all ages. The parasites live in the small
intestine and attach themselves to the lining of the intestine. Hookworms are bloodsuckers, and if there are enough of them they can cause severe anemia (deficiency of red blood cells) and even death. All a cat has to do to become infected is walk
on soil where the eggs or larvae are present. The larvae can
penetrate the skin directly, or the eggs can enter the cat's system
when he licks them off his feet and swallows them.
Sign Of Hookworms In Cats
Cats infected with hookworm (especially kittens) tend to look
very thin, and their fur is scruffy and dull. Diarrhea tinged
with blood is common in both young and older cats. The vet
diagnoses hookworms by microscopic examination of the stool for the
parasite's eggs.
Treatment Of Hookworm In Cats
Products available for treatment of hookworm include HomeoPet
Worm Clear, Drontal Feline, and Heartgard30. More than one treatment
may be necessary to eliminate the problem.
Tapeworms
Tapeworms are flat and actually got their name from their shape, and their resemblance to pieces of tape. It is possible to see them moving in the cat's stool after it has passed. Tapeworm infections occur
when the cat eats an infected intermediate host - usually the flea (If
a cat happens to have fleas, it may accidentally swallow one when
grooming itself). Mice, rabbits and fish can also act as hosts
for the tapeworm, and a cat that eats raw meat from any of these hosts
can become infected.
Signs Of Tapeworm In Cats
Tapeworms seldom cause much real trouble beyond mild diarrhea and some rectal itching.
You're most likely to spot them by examining the hair around the rectum
for the rice-like segments that contain the tapeworm eggs, but because
cats clean themselves so thoroughly, this is not always possible.
Treatment Of Tapeworm In Cats
As with so many parasite problems, treating tapeworms is a two part task - you
have to rid the cat of tapeworms and rid the environment of the
intermediate host, most likely fleas. So, once you get rid of the
tapeworms, be sure to get rid of the fleas! See the section on
fleas for more information. Products available for the treatment
of tapeworm include Tape Worm Tabs-Cat (praziquantel), Drontal Feline,
Droncit, and Cestex (epsiprantel).
IMPORTANT!
Don't
try to solve a worm or flea problem by yourself with "over the counter"
medication, as many of these medications have caused fatalities in
cats. ALWAYS consult your vet for his/her recommendations!
Roundworms
Roundworms are long, white worms that look like spaghetti, and
they are easy to recognize in the cat's stool or vomit. It's
probably safe to assume that most kittens will contract roundworms from
their mother, but older cats usually become resistant to them.
Under normal sanitary conditions these parasites are not such a serious
problem as other, faster-developing parasites.
Internal Parasites In Cats: Roundworm, Hookworms, Tapeworms And Heartworm
Heartworm
Heartworm in cats is caused by a worm that lives in its adult stage in
the right side of the cat's heart. Heartworms are transmitted
from one cat to another by mosquitos, and do all their damage in the
adult stage, by which time the worms can be up to 12 inches long.
Heartworm in cats is a serious matter and can be fatal.
Signs Of Heartworm In Cats
Severe infection by adult heartworms can cause coughing, breathing
difficulties, fatigue, and general weakness. As the disease
progresses the cat's heart, liver, and lungs become severely damaged.
Visible symptoms of the disease do not usually appear until the
advanced stages, by which time the disease may be irreversible.
Diagnosis of heartworm disease is based on the cat's history, clinical
signs, chest x-rays, and blood tests to locate the presence of the
parasite.
Treatment Of Heartworm In Cats
Heartworm
in cats is generally more rare in cats than in dogs, primarily because
cats spend a lot more time indoors, with less exposure to mosquitos.
However, the disease in cats is very difficult to treat, and about 70%
of cats will die from the disease once any obvious symptoms are
present. Your best course of action is prevention using once a
month Heartguard for cats, or Revolution.
