There is no problem with giving a FeLV positive cat the FeLV vaccine.  Some
would say it was just a waste of money (for the positive cat) but there are
people on the FeLV lists that have given their positives cats the vaccine
every year and some claim to have some very old cats with FeLV.  I believe
one had had a cat that lived to be 22.  I don't think there is any hard
evidence as to whether it helps or not, but it won't hurt them.

I'm sure you will hear from others who do it.

I have several cats who are 5+ years old, and all tested FelV
negative years ago when I adopted them.  However they are inside -
outside cats, and are also exposed to rescued cats I bring home
to be adopted out. These cats also tested neg.  but there is always
that window area where FelV may not show up yet or the test may be

I want to have my home cats vaccinated for FelV just in case. Please
give me some info. on this...... Do I need to retest them all first,
or is it safe to give them the vaccine without testing them. They all
appear to be in excellent health, but if they should be pos. would
the vaccine hurt them??

Thanks for your help,
