Yes, I was just explaining what positive on the IFA meant. :) Positive on the snap and then positive again at least 6 weeks later is most likely positive. Tanya --- On Mon, 4/18/11, Pam Norman wrote: > From: Pam Norman > Subject: Re: [Felvtalk] Update on Poppy/IFA test > To:

Positive on IFA means it has reached the bone barrow and there is no clearing the virus. If she is positive on the snap test again (and it has been at least 6 weeks since she last tested positive) then she is FeLV positive, but you need to wait the full 6 weeks to give her body time to clear

nows, please correct me. So I'm gather that perhaps the antigens hadn't cleared yet at the time of the snap, and Linda seemed to agree with that. Anyhow, this is a 1.5 yr old cat, so the question is, with a light pos on Elisa snap test, and a negative on the followup IFA test, what

Hi Laura, In many cases I would say this is true, because those animals are going to be the easiest to find homes for, and lets face it the ones that have health issues are going to cost the rescues lots of money to "fix" and many if not most people who adopt from rescues don't want to

I would also like to add that the "picking and choosing" primarily occurs with dog rescues, not cat rescues. We've had cat rescues take FeLV+ cats from us, cats with one eye, cats with real problems, very senior cats. It's not all of them, by any means, but quite a few of the dog rescues who tak

Shelters don't kill cats. The public does. I work for a county shelter and yes, we do euthanize. As few animals as possible, but we do euthanize. It isn't the shelters' fault. They get incredible numbers of animals dumped on them every day. Most of our cats are friendly cats picked up as strays.
