FIP is a viral disease of that is
brought on by some strains of the feline coronavirus. There are
several strains of this virus, only of few of which cause
FIP.
Many cats infected with the feline coronavirus do not show any
symptoms during the initial viral infection and actually have a
natural immune system response during which they develop
effective antiviral antibodies.
However, 5-10% of infected cats develop full blown FIP as a
result of a virus mutation or because of misfired immune system
response. FIP is almost always fatal.
What happens when there is an errant mutation / immune system
response is that the white cells that are supposed to protect the
cat are themselves infected with virus. These infected white
cells then carry the virus throughout the cat's body. This
results in an inflammation around vessels within the tissues
where these infected cells go (abdomen, kidney, or brain).
WHAT ARE FIP SYMPTOMS?
Fevers unexplained by anything else are common. In fact cats that
develop FIP often appear to have a very sudden onset of symptoms.
These then develop quickly and increase in severity over the
course of several weeks, ending in death. Otherwise, there are no
unique symptoms that unrelated to other illnesses (loss of
appetite, weight loss, lethargy /
depression,hair / skin problems,
fevers).
CAN MY CAT GET FIP?
Any cat that carries the coronavirus can be at potential risk of
then developing FIP...However, most often it is immune
system compromised cats (kittens, cats infected with feline leukemia, and older cats) that actually develop the
disease.
Most cats that develop FIP are less than two years old (cats are
most commonly infected as kittens by their infected
mothers).
FIP is not highly contagious...however it can be transmitted
through cat to cat contact and exposure to feces. If your cat has
FIV it is probably better to isolate him from your other
cats.
Note that the virus can also live outside in the environment for
several weeks so thorough cleaning is important in an area that
has housed an infected cat.
The good news is that FIP is not relatively uncommon in the
broader cat population. When found it is most commonly located in
multiple cat settings like shelters / catteries.
HOW TO PREVENT FIP
Keeping cats healthy and minimizing exposure to infectious agents
is the best way to lower the chances a cat will develop FIP.
Especially in multiple-cat environments, litter boxes should be kept clean and
located away from food and water dishes. Litter should be cleaned
daily with the box regularly thoroughly cleaned and
disinfected.
Cats suspected having FIP should be separated from other
cats.
The bad news is that there is no good and conclusive test for
FIP! This is because cats that carry the coronavirus will test
positive. Remember that most cats with the corona virus carry a
non-FIP inducing strain or are sufficiently healthy that they
will not develop FIP....As a result, a positive test means only
that a cat has had a prior exposure to coronavirus and nothing
more.
TREATING FIP
The bad news is that there currently is no known cure or
effective treatment for FIP. FIP is a fatal disease. - Simba
