Oh crap.


Kasia, I'm so sorry. I've been afraid to do that

Please, take a deep breath. Your life hasn't ended, and neither has theirs.


We need to think this through.


Okay. From what I see Jack was the original to test positive for FeLV, and he also has Lymphoma, which is currently being treated.  

Your other cats are now testing (Elisa?) positive for FeLV. According to this article;




there is a possibility that the others MAY not be persistently infected.


"The most widely used in-practice tests are antigen ELISA and

immunochromatography. As the prevalence of FeLV infection has decreased in

many European countries, also false positive test results tend to increase.

Therefore, a doubtful positive result in a healthy cat should always be confirmed,

preferably using provirus PCR (DNA PCR) offered by a reliable laboratory. A

positive test in a cat with clinical signs consistent with FeLV infection is more

reliable, as in sick cats the prevalence of FeLV is considerably higher.

Cats testing positive may overcome viraemia after two to sixteen weeks - in rare

cases even later. Therefore, every test-positive healthy cat should be separated

and retested after several weeks or months; depending on compliance of the

owner, retesting can be done still later (up to one year) when it is highly unlikely

that the cat will clear the viraemia."


It's the same thing I'm facing, if not to the same extent. I don't know if Gribble infected Mako, or vice-versa. Or are there other positives in this bunch, that will show up later, when they have health issues down the road.


It's all very complicated. Every tine I think I get a handle on it, something else happens.


So I'm trying to go one day at a time. I will make their lives as wonderful as I can, and as comfortable. I will try to make wise decisions, though there are no quarantees. Basically, I will do the best that I can.


Again, I'm so very sorry that this has happened.

Yesterday I had the rest of the cats tested for FelV, and they all turned out to be positive. I  have 6 cats suffering from FelV and one has lymphoma; I feel like my life has just ended. 

I unknowingly mixed two FelV cats into my group, and the two positive cats
are now 5 years old and in apparent good health in spite of being positive.
There were several other older cats (not kittens) who were exposed and only
one became very sick and had to be PTS.  The other 9 cats are still fine.
One has been tested twice and still remains negative. FelV is not always a
death sentence for older cats who are exposed, but sadly I have found that
kittens born to a FelV mother and testing positive almost always die at
a year or so old.  Good luck with your cats and welcome to the group.
