Hi Lorraine

What I have suggested to many in this group, for treatment of FeLV, is the 
following combination of medications:

Winstrol (Stanazolol) - 1 mg twice a day

Doxycycline - 1/5 to ¼ tablet (100 mg) twice a day

Prednisolone - ½ 5 mg tablet, twice a day

If there are problems with the intestines (vomiting, constipation, slow moving 
stools, stools of large diameters, all of which might be indicative of the 
effect of the virus on the intestines) you can try adding ¼ tablet of 

If the haematocrit level is REALLY REALLY low - like below 5-8, you might 
consider starting the Winstrol at 2 mg twice a day for a week, to try and 
kickstart things quickly, but given that there is going to be a likely increase 
in liver enzymes with the use of Winstrol, recognize that this might also 
increase the liver enzymes faster.

Lorraine, you will very likely encounter great resistance or skepticism 
regarding the use of the Winstrol. It is an anabolic steroid, associated with 
some doping scandals in professional athletics, so it has a bad rap in the 
sports world. I haven't yet figures out why this should matter in the animal 
world, especially since NOTHING else works to turn back on the red cell 
production in FeLV, but I am just warning you that you may get an unexpected 
reaction from the vet. If not, terrific - carry on. If you do, many people in 
this online group have managed to procure it themselves.

I also suggest blood work up front, so you can gauge how well the Winstrol is 
working to address the anemia. The other thing to resist, however, is that 
Winstrol may well bump up liver enzymes - sometimes dramatically. Vets will get 
alarmed at this and will often tell you to discontinue the Winstrol, but I 
would resist this. The liver enzymes almost always go back to normal once the 
Winstrol is discontinued, with no lasting harm to the liver, and there is 
really nothing else to use for this disease.

How long you need to stay on this regimen will depend on the lab results. Once 
the anemia is resolved (haematocrit, haemoglobin and reticulocytes back to 
normal) you may need to continue with the Winstrol for a more time. My 
experience was that every time I wanted to wean my cat off the Winstrol, his 
haematocrit would immediately drop. I kept him on the Winstrol until I didn't 
see a drop in haematocrit when I began to wean him off. My cat's results were 
horrible, before starting the Winstrol. (His haematocrit was FIVE, with ZERO 
percent reticulocytes, and I had given him several blood transfusions, which 
obviously were only a temporary fix.)

I hope this helps.

Subject: [Felvtalk] Baby's intro

I'm a new member. While caring for my cousin's cat Baby here in my home during 
his 2-week vacation in Mexico, we had bloodwork done ahead of the dental 
cleaning that my husband and I agreed to have done for her.  She turned up 
positive for FeLeuk on ELISA, IFA, and PCR--the triple whammy. She's already 
slightly anemic.
Baby was first vaccinated against FeLV in Jan. 2018 before her first-ever stay 
with us.  But the booster due at week 3-4 was missed. This was followed by a 
bite puncture in Dec. 2018. So I suspect that first vaccine was worn off by the 
time of the bite.
Baby is 11 and in otherwise good health, so I hope there's a good chance she'll 
still live her "normal span" --and perhaps even die of something unrelated. But 
the anemia is not a  good sign, I'm told.
I am putting together information for my cousin to try to take the edge off of 
the terrible shock this will give him. I'm of course including cautions about 
keeping her indoors, etc., and following up on any symptoms, etc. I hope to put 
off telling him until just before he flies back to the US.
I suspect my cousin would prefer treatments that are oral as opposed to IV. But 
his wife is trained as a nurse, so perhaps they would be willing to try 
difficult-to-administer treatments. I'm not sure how much room their budget has 
for expensive, imported treatments like feline interferon omega.
On general principles: in our home, Baby has been kept entirely separate from 
our own six cats, who are vaccinated against FeLV except for one little guy who 
has FIV whom we avoid over-vaccinating. We have always hand-washed after 
handling Baby or her dishes, even prior to this diagnostic info.
I think I've drawn the complete picture, but please ask if I've left out 
something important.
FWIW, I have a degree in biology and am a medical writer, so I don't scare 
easy, and I understand big words...mostly. (-:
