I have mixed FELV positive cats with negatives for at least 8 years and no problems. My vet said that as long as the negatives were vaccinated, all would be okay. In the last 2 years, no one has received any vaccinations and no problems. Could be that as Lance said, the adults have developed an immunity. All 4 of my cats are healthy. I lost 3 last year due to old age (17 years), not felv..
