Those two little babies are so adorable. I really hope they turn out to be negative. How did you manage to get them to be still to take such great photos? When I try to take photos of my fosters for our website they are too busy playing to sit still for a photo shoot.
I didn't foster the mama kitty or kittens that had FeLV but last I heard they waited like a month and a half and did the IFA on the mama kitty which turned out to be negative. They did individual snap test on the four kittens. Two of the four kittens tested positive on the snap test and the other two tested negative. So weird. They were able to adopt out the two negative kittens, same home I believe, although they did tell the adopters about the Mama and the two positive littermates. The other two littermates haven't been adopted yet. I'm not sure about the Mama cat. I'll have to e-mail them to find out what's going on right now. They really need to re-test the Mama and the two positive kittens and I don't know if they realize it. Good thing you sent this e-mail so I'd remember to talk with them. I have this book called "The Cat Owner's Home Veterinary Handbook" which is written by several different vets and I'll write exactly what they say about testing. It's a little long so just ignore this next part if you don't want to know. "Currently there are two tests available to detect FeLV infection. 1. The IFA test, performed by a reference laboratory, detects virus antigen in infected white blood cells. This indicates that the bone marrow is infected and there is a high probability that the cat is persistently viremic and is shedding the virus in his saliva, making him infective to other cats. About 97 percent of IFA positive cats remain viremic for life and never extinguish the virus. 2. The ELISA test detects virus antigen in whole blood, serum, saliva and tears. Blood is the recommended sample for testing. A rapid screening leukemia test kit is available for home and veterinary clinic use. The ELISA test is more likely to detect weak, early, or transient infections. The common practice is to screen for FeLV using the ELISA test. If positive, the cat may have a transient viremia from which he will recover completely, or he may be in the early stages of a progressive infection. A positive ELISA test should be confirmed with an IFA test. A positive IFA test indicates that the cat is shedding virus and is capable of infecting others. The ELISA test should be repeated in 8 to 12 weeks to see if the virus has been eliminated. The IFA test should also be repeated at this time because if the cat was in an early stage of infection, the IFA initially may not have been positive but may become so after 12 weeks." That's the direct quote from the book. The books also mentions about latent (dormant) type infections where the cat is able to eliminate the virus from blood and saliva but the virus still persists in the bone marrow and in T-cell lymphocytes. It says "over many months the majority of latent-infected cats overcome and extinguish the virus, so the incidence of latent infection after three years is quite low." During this period of latency though it talks about sometimes stress and illness can reactivate the virus. As far as testing to find out if a cat has a latent virus it says - "Cats with latent infection test negative on both the ELISA and the IFA tests. This is because the virus is absent in both serum and white cells. The only way to diagnose a latent infection is to remove a sample of the cat's bone marrow containing the dormant virus and grow the cells in culture." Well, that's what the book says anyway. Not that it is an absolute authority but most of the other reading seems to say the same thing. What's funny is that you could have a cat that has a latent infection and you would never know it unless the virus got reactivated and the cat became sick. So you could do 10 different test on the cat and they would all be negative but then a year later the virus could become reactived then the cat tests positive. I look at all my cats and my fosters and wonder if any of them have a latent infection. You just never know and that's the really scary part. One encouraging thing though is that only about 30% of the cats exposed to the virus actually become permanently infected and will die from the disease. Of course 30% is still too many. The problem we in rescue have is that keeping the cat for 12 weeks and doing several different test before trying to adopt out is not always possible. It sucks. As far as immune system stimulants, I'm not sure what to recommend. I hear of so many different things that I can't remember what does what and what is good for what. I would think a decent diet is a good basis to start with. Probably not the cheapest cat food they sell. But the supplements are just way too confusing for me. Natalie and some of the others might have some opinions. “I am not interested to know whether vivisection produces results that are profitable to the human race or doesn’t….the pain which it inflicts upon unconsenting animals is the basis of my enmity toward it, and it is to me sufficient justification of the enmity without looking further.” – Mark Twain > From: ana...@gmail.com > Date: Tue, 2 Aug 2011 13:15:18 -0500 > To: firstname.lastname@example.org > Subject: Re: [Felvtalk] doubts on two FeLV positive kitties > > John, > Thanks, that's the idea I had too...
