I'm so sorry to hear this. I've been meaning to create a thread on my FeLV+ kittens I trapped last year, but I need to tell you now.

Two of the four had a "soft positive." My vet strongly encouraged me to wait and retest with the IFA test. This is the blood test that Moosmom referred to.

That's because (according to my vet) almost 25% of the positives reported by the elisa test (snap test) done in the office are FALSE POSITIVES!

It is also possible for the kittens to fend off this infection and be negative for the remainder of their lives.

(My kittens tested negative with the IFA test twice, almost five months apart. They went to a happy home. My vet was so disgusted by the false positives that he refunded the snap test cost.)

Like you, I was absolutely devasted at first. But instead I got to see two darling kittens grow up. They grew up in my bedroom/bathroom but ultimately they were OK.

I have a lot of good information on FeLV if you should need it. Let me know.
