I read in multiple literature that 2/3 of cats who were expsed to the virus
will thrwo off the Felk virus as well. One I saw is in the peteducation web
page in felk section about it does not tell where the back up study came from..
Also, one of the medical book I have for cats also say the same thing --
Here's what I copied from the website..from the peteducation.com
What happens to a cat after being exposed to FeLV?
If the cat becomes infected from the exposure, 2-4 weeks later, in the
acute<javascript:popupWin1('/dictionary_term.cfm?term=acute&cls=1', 50, 50,
350, 300)> stage of infection, large numbers of the virus can be found in the
bloodstream (viremia). Cats in the acute phase usually do not show signs of
disease. If they do, the signs are usually mild fever, slight lethargy, and
swollen lymph
nodes<http://www.peteducation.com/article.cfm?cls=1&cat=1352&articleid=318>
(lymphadenopathy). When an adult cat is exposed to FeLV, four things can happen:
1.. Approximately 30% of adult cats will not be infected due to inadequate
exposure.
2.. 30-35% of adult cats have a transient infection; over the course of 6
months or so, the cats will eventually kill all of the virus.
3.. 5-10% of adult cats will develop
latent<javascript:popupWin1('/dictionary_term.cfm?term=latent&cls=1', 50, 50,
350, 300)> infections; these cats will not be able to kill all the virus, but
will be able to hold it in check. This is called a latent infection. These cats
usually show no signs of infection and usually do not shed virus in their
saliva or other body secretions.
Queens<javascript:popupWin1('/dictionary_term.cfm?term=queen&cls=1', 50, 50,
350, 300)>, however, may still pass the virus in utero or through the milk.
4.. 30% of adult cats will become persistently infected; these cats will not
develop an adequate immune response and will remain permanently infected with
FeLV. These are the cats who will become ill and die of FeLV-related diseases,
usually within 2-3 years of infection. These cats will shed large amounts of
virus in their saliva.
Age is a very important factor in determining what will happen after a cat is
exposed to FeLV. Almost all FeLV-exposed kittens less than 8 weeks of age will
have persistent viremia and show signs of disease during the acute phase. As
kittens get older, there is the probability of becoming persistently infected
after exposure lessens, until it reaches approximately 30% in adulthood.
The prevalence of FeLV infection is highest in cats between 1 and 6 years of
age, with a mean age of 3 years. Males are 1-½ times more likely to be infected
than females. This may be due to the frequency in which intact males roam and
fight.

Hey MC,
I, too, need to track down that 70% figure. And my understanding is that
that is 70% of healthy, *unvaccinated* cats can throw off the virus. So with
vaccinated cats it would be even better.
Is that your understanding as well?
Alley Cat Allies has some good documentation on how spaying and neutering
more animals is a better answer to stopping the spread of FELV than is testing.
They recommend *not* testing healthy, asymptomatic cats.

Whenever our feral cat program gets started, that's the way we will operate.
If only there were 48 hours in the day:)

the most important info, i believe, in the last few years, is the research
showing a genetic predisposition for the mutation from the usually benign
corona virus to the horrible FIP. when i was still involved with VIN (the
parent of www.veterinarypartner.com<http://www.veterinarypartner.com/> that
belinda references), this relationship was just starting to come out, through
the Feline Genome Project results from UC Davis and other participants. the
winn feline foundation (whose link i don't happen to have right at hand but a
search will pull it up, has current position papers on FIV, FeLV and FIP.
personally, i disagree with their overly pessimistic stats on both FIV and
FeLV, but that's me.)
as belinda says, the information is out there and we have a responsibility
to make sure that what we don't add to the confusion by repeating stuff that is
NOT accurate.
(and yes, i STILL haven't found where, exactly, the oft-quoted figure that
" 70% of healthy adult cats can throw off the FeLV virus." but i'm still
looking.)

Here are some sites with info about FIP. Just because the same
misinformation keeps getting repeated isn't going to make it true. To many
cats pay with their lives when incorrect information is tossed about. To say a
cat is suspected to have FIP is one thing, to say is is confirmed without the
proper verification procedures being followed is in my opinion criminal.
----------------------------------------------------------------------------------------------
This is from the VeterinaryPartner.com website written and maintained by
vets, it is from 2002 so even this is probably no the most accurate info:
http://www.veterinarypartner.com/Content.plx?P=A&A=232<http://www.veterinarypartner.com/Content.plx?P=A&A=232>
FIP effusion fluid is thick, tenacious, straw-colored to deep golden,
and clear to slightly cloudy.
From another Vet Website, again written in 2002:
http://www.vetinfo.com/cencyclopedia/cefip.html<http://www.vetinfo.com/cencyclopedia/cefip.html>
When cats have the "effusive" form of FIP in which abdominal fluid
accumulation occurs, the thick, straw colored fluid has characteristics that
strongly suggest FIP. It is possible to run a more specialized lab test, a
polymerase chain reaction test for FIP, on this fluid. This type of testing is
more accurate than FIP antibody testing but still is not definitive. Blood
tests to compare the various protein levels in the blood can be very suggestive
of FIP infection, as well. High immunglobulin levels are very suggestive of FIP
in the presence of clinical signs. Despite all of this, there is no clear-cut
way to make a sure diagnosis of FIP prior to death.
This person does Dr Addie's website and probably has some of the most
current and factual info on FIP:
http://www.orionfoundation.com/Information.htm<http://www.orionfoundationcom/Information.htm>
3) Verify FIP through histopathology. Simply necropsy is not enough.
Microscopic evaluation of tissue from biopsy or necropsy by a trained
pathologist is considered the only diagnostic proof of FIP. Where available
request immunoperoxidase examination of tissue to verify presence of Corona
virus in suspect tissue.
