Yes, an IFA only tests if it is circulating in the bone marrow, which means 
they are beyond the point of being able to throw it off.
A positive Snap still means they have FeLV, as long as it is administered 
correctly.
There seems to be a lot of confusion about that.

Still, thank you for keeping her.I currently have 4 FeLV's & wouldn't trade 
them for the world!

Only IFA. I'll ask that she be retested with the Elisa too. Thanks for pointing 
that out. I thought the IFA was the definitive test but may not be positive 
right away when acute symptoms present.

Also a clarification, my Tux as a kitten story was 5 years ago. She's now an 
adult. Even back then the vet was ready to destroy her if that snap test came 
back positive. Of course the current vet wanted to put her down at the first 
positive snap test with anemia. She may not even be infected with FeLV...but 
even if she were infected we wouldn't consider that option until her quality of 
life was so bad to warrant that (and treating her condition to give her a 
fighting chance at some recovery). 

Thanks. again. Dave

Dave was she just retested on the IFA, or on the Snap test also? A positive 
Snap with a negative IFA is still a positive cat.

 different...but I could never destroy a healthy kitten. I am very happy to see 
an entire community on this forum that feels as I did (and reinforces what I 
thought was right at the time). Unfortunately most people will do what the vet 
says...and that is very sad.
