Doing a web search I come up with everything from they can be tested at any
time to it's not accurate till 6 mos. At what age do you usually test kittens? There are about 5 doctors at the veterinary practice I take my cats to. The vet I usually deal with told me (last fall) he couldn't test kittens until they were at least 12 wks. old. When I took the most recent litter up to be checked (when they had diarrhea and weren't eating) I saw a different (younger) vet who told me she could test them then (they were 2-3 wks old). She did and the results were negative. She warned that there could be a false positive at that age but if it was negative then they were negative. The rescue group we're fostering for told me I shouldn't trust the results because they were so young. So now I'm confused. The kittens are now 7 weeks old and are itchy to get out of the cat play pen I'm keeping them in. I don't want them interacting with my resident cats unless I'm pretty sure they aren't positive. So do I need to get them re-tested? Are they old enough yet? Thanks W |

I have another one who nearly died 2 months ago, tested out positive to FeLeuk -- did a CBC and it came back with low white count, 80% lymphocytes but NO NRBC's. He's alive and well on a regimin of non-steroidal anti-inflammatory. So I'd say testing again at 6-7 months and maybe even 6 months again after that. because they can hold the virus in their bone marrow which will giveyou a negatiove test, then it can suddenly "bloom."

Both shelters I foster for test them at 6 weeks of age, when they're old
enough for their first set of vaccs. Sorry that's all the help I can offer. "Wendy" wrote in message ...

The first doctor is telling you what I have always been told. A negative
result is pretty much assured, where as a positive might be a false positive from the mom's antigens. HOWEVER.. that being said, let me tell you that it takes six weeks to incubate. So test when they are at least six weeks of age, then retest after six weeks to be 100%. Or should I say six weeks past any possible exposure. This being said. Getting Felv is not easy. I have had it in my home twice, and my resident, well established cats have not gotten it. My younger (under a year) one did. However, he only ever tested positive, he never came down with symptoms, and with some loving care, high quality food, and high doses of vitamin C, he now tests negative. "Wendy" wrote in message ...

![]() This being said. Getting Felv is not easy. I have had it in my home twice, and my resident, well established cats have not gotten it. My younger (under a year) one did. However, he only ever tested positive, he never came down with symptoms, and with some loving care, high quality food, and high doses of vitamin C, he now tests negative. Just so you know your cat never had it, he tested positive because he was showing exposure to it but managed to fight it off and never got the virus which is why he is now negative. There is no cure for Felv so he could never have had the virus. As for when to test you can't really test kittens until their veins are big enough to get blood out of with a needle which is usually 6 weeks. To test before then you have to use a different test not a blood test which some vets don't think is as accurate. While its true that a cat can test positive and later negative because they have been exposed to the virus and fought it off, it is also true they can test negative and then turn positive if the test is done to quickly after exposure. All this makes it very confusing but its an extremely small percentage that will come down with felv after a negative test. On testing kittens and having experamented with tests I have never yet found a kitten less then 12 weeks to be positive where the kittens mother has been negative and I've also never seen a positive mother who didn't also have positive kittens. It might be a bit of a waste of money having to test all the kittens and put them through that where its possible to test the mother. |

It totally depends on the situation. An exclusive relationship between
mother and kittens I would tend to agree with you, but if there is any mingling of families, it happens. (aka a shelter environment or a large feral colony) On testing kittens and having experamented with tests I have never yet found a kitten less then 12 weeks to be positive where the kittens mother has been negative and I've also never seen a positive mother who didn't also have positive kittens. It might be a bit of a waste of money having to test all the kittens and put them through that where its possible to test the mother. |
