I say mix, no need to vaccinate healthy adult cats. The FELV vaccine is MORE apt to CAUSE vaccine associated sarcoma (cancer) than it is to improve immunity against FELV in adult cats. In other words, there are more BAD things against the VACCINE than there are bad things against mixing adult cats with FELV+ cats.
And yes, I can back that up with facts if needed. That is, of course, MY personal advise, and it will vary between members here.
