Re: [Felvtalk] Re anemia and negative IFA (Dave)
And the big problem is, is that the majority of the public isn't informed and hang on every word a vet says. They trust them for the best advice. It's up to us to spread the word as much as possible.

What is wrong with the vets? I was not as lucky as David, neither my River :((( Mine was killed by a no-kill animal shelter...Some of you might remember... By the way I sent a complaint letter, called a few of their top supporters, Executive Director called me and I was VERY accurate and not accepting their bs, the director of the faclities stepped down a while ago.

Re: [Felvtalk] Re anemia and negative IFA (Dave)
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!

Re: [Felvtalk] Re anemia and negative IFA (Dave)
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.

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. If both tests were negative then she is negative.

Re: [Felvtalk] Re anemia and negative IFA (Dave)
Thank you for not putting Tux down. Somehow the word has to get out there that it is totally unnecessary to euthanize positive cats. I tell everyone I know that has cats and hope they spread the word. This forum is awesome. They are intelligent, informed loving people that give hope when it is needed. And HOPE is so important with this disease. Good luck with Tux. My wish for her is a long happy life(-: Sent from my iPhone On Feb 6, 2013, at 8:34 PM, Dave Arthurs wrote: > Update on Tux.

Re: [Felvtalk] Re anemia and negative IFA (Dave)
Update on Tux. Recap: She tested positive for felv on the snap test in December and negative on ifa. She is a felv vaccinated house cat that presented with immune mediated hemolytic anemia. She was treated with prednisolone and doxycycline. She responded well to treatment tho no cause was identified because the vet was convinced she was felv+. This week we retested her. Weight is up 1 lb. and red blood cell count is normal. Negative on ifa. The cause of her anemia is still unknown but the vet has let the felv diagnosis go now. Thank you everyone so much for all the advice. It's heartbreaking to read about the struggles we all go through on this forum for the love of our pets. When we got tux the vet tested her for felv. She said if she was positive that she had to be put down right away. She was very insistent. I knew in my heart that was wrong and wouldn't let her do it. Of course if she were suffering that would be different...but I could never destroy a healthy kitten.

Re: [Felvtalk] Re anemia and negative IFA (Dave)
The official diagnosis/condition from the pathologist is immune mediated hemolytic anemia/IMHA. We don't know the cause yet. We're treating for parasites (doxycycline)...and with prednisone to suppress the immune response. We'll repeat the IFA in a month. She is responding very well to treatment...the immune response to her own blood has diminished, gained back 1/4 pound, her CBC increased 50% and her new blood cell count was up 5x. We get another blood test tomorrow. She was still barely below the recommended CBC for transfusion...but is doing well despite everything. She's active though she won't play. There are a couple of times she tried to rough-house with her sister and gave up (it was actually funny to watch...after a few minutes of chase, she gave up and laid on her back...her sister came over and gave her a very gentle little nip on the butt...to which Tux let out a whine of indignation). Our vet admitted some doubt about FeLV but is sticking with it for now. I read online that for 60% of IMHA cases it is never determined what the cause was. The cats did act like they had fleas about six months ago (and we treated, though we never saw any fleas). Tux is also the garbage collector...she eats everything on the floor...so it's also possible she at something toxic. Thanks again everyone. I will follow up with any new findings.

Re: [Felvtalk] Re anemia and negative IFA (Dave)
It's rather unlikely but not impossible that there was a false negative in the ELISA test, especially given the history of the cats. The IFA test is not perfect either. Have you considered any other possibility, such as Hemobartonella, which can be treated with doses of Baytril? I have had two cats who suffered from hemobartonella. It's difficult to diagnose but some of Tux's symptoms seem to be those of this disease. Fleas spread hemobartonella so you might want to treat Jet with Frontline Plus or Advantage for Cats. Tests can come up with all sorts of incorrect results. Several of my adult cats off the street tested positive for FeLv but had so many other issues like URI, mange, etc. that their immune systems were overwhelmed. After treatment for the other problems and after three months these cats tested negative for FeLv. You need to retest both cats but first bring the problem with Tux under control. Maybe you should seek a second opinion from another vet not associated with the woman who seems to test for a pre-determined opinion she has.

Re: [Felvtalk] Re anemia and negative IFA (Dave)
Dave, I have to agree with you. I have fostered many FeLV kittens who were positive from birth. Most died before they were 2 yrs old. Only one survived until 4 yo.

Re: [Felvtalk] Re anemia and negative IFA (Dave)
Well, the SNAP could indeed be wrong, Most vets now use the 3-way SNAP tests - FIV+FeLV+Heart Worm. Our shelter had horrible problems with these tests producing false negatives. We stopped using them. We got ahold of the old tests. Is the anemia better now? I think you said it was up to 15% from 10%, thought it's my understanding that that can vary, too by whether or not the cat is being given fluids.

Re: [Felvtalk] Re anemia and negative IFA (Dave)
The antibiotics are usually because they are treating for Hemobartonella, whether they know the cat has it or not - I guess it can be hard to see. Hemobartoella is supposedly more common in FeLV cats, though I had a negative cat who had it. Usually if a cat tests positive on a SNAP test they re-do it, to make sure the test was done correctly. Your cat could easily have been exposed to the virus before the original SNAP test years ago. It can take 3 months after exposure for a cat to test positive. If you re-test on the SNAP & Tux still tests positive, you can have an IFA done. The IFA is done to see what the progression of the virus is. If the IFA is positive it means the virus is replicating in the bone marrow & cannot be thrown off. A negative IFA with a positive SNAP test does NOT mean the cat is negative & the SNAP test is wrong. It simply means the cat still has a chance of throwing off the virus. Good luck. If Tux does have Hemobartonella she should respond quickly to the antibiotics.

[Felvtalk] Re anemia and negative IFA (Dave)
Dave, I'm no expert by any means, but I have had a bit of experience with FelV as I have 16 cats at home and more in my own rescue shelter in a building I bought in 2004 and made into a cageless sanctuary for cats. I have several FelV cats there. The only thing I can think of regarding Tux is that she may have been exposed to the virus before you adopted her. It can take about 6 weeks after exposure to the virus before the Elisa test shows a definite positive or negative. Anemia is something several of my FelV cats have died from, and a few of them were positive as long as 5 years before showing any symptoms. Usually positive kittens die within the first year, but not always. Approximately 1/3 of all positive cats carry the virus and never show symptoms, 1/3 die, and the other 1/3 have immune systems strong enough to kill the virus. As for the vaccine preventing FelV, if Tux had already been exposed before you adopted her the vaccine would not have kept her from developing FelV. At this time I have a litter of four 7 month old rescued kittens who all tested positive. There mother was feral and probably FelV positive. Sadly, one died last week and the other three still appear very healthy. I will retest them in a couple weeks and hopefully they will be negative. The difference in your Elisa test and your IFA test is puzzling. You wrote that her blood test showed she was having an immune reaction to her own blood, and this appears (to me) to be more of an auto-immune problem rather than FelV. Please keep us updated on Tux.
