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. ----- Original Message ----- From: Kelley Saveika<mailto:[EMAIL PROTECTED]> To: felvtalk@felineleukemia.org<mailto:felvtalk@felineleukemia.org> Sent: Friday, June 29, 2007 8:14 AM Subject: Re: FIP Facts - WAS - Suzie crossed the bridge 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. http://www.alleycat.org/pdf/test.pdf<http://www.alleycat.org/pdf/test.pdf> Whenever our feral cat program gets started, that's the way we will operate.

(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.)

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. -- Belindahappiness is being owned by cats ..Be-Mi-Kittieshttp://bemikitties.com <http://bemikitties.com/> Post Adoptable FeLV/FIV/FIP Cats/Kittens http://adopt.bemikitties.com<http://adopt.bemikitties.com/> FeLV Candlelight Service http://bemikitties.com/cls<http://bemikitties.com/cls> HostDesign4U.com [affordable hosting & web design] http://HostDesign4U.com<http://hostdesign4u.com/> ------------ BMK Designs [non-profit animals websites] http://bmk.bemikitties.com<http://bmk.bemikitties.com/> -- Spay & Neuter Your Neighbors!
