Julia,
I think potentially any cat that has had the virus for too long and
the virus hasn't gone to the bone marrow can become negative. However I
do recall a story from years ago where someone whose cat had the virus
in the bone marrow and had been + for 3 years supposedly turned
negative. I don't even remember where I heard the story and therefore
can't put much substance to it.
There are some things you can do to build up the cat's immune system to
help them be stronger and hopefully help them fight the virus off.
Interferon is a good immune booster, a good quality food, no stress,
there is something called Mega C Plus that one lady I spoke with said
turned all 10 of her positives negative. They are according to her
negative to this day. She was referred to me by a rescue that I had
called about a positive. The thing with the Mega C Plus is the cat
takes as long to turn negative as it has been positive (for instance if
the cat has been + for 10 months it will take 10 months for it to turn
the cat negative), I have not used it for that because when I found out
about my Bailey had been + for 11 years, there wasn't a chance he would
probably live long enough to turn negative, but it is suppose to be a
good immune booster also.
In my honest opinion stress is the biggest thing that sets the virus off.
