FeLV is worse than FIV, in that most cats infected with it do not live to old age. Some do, though, and some live to middle age. There are people on this list who have positives who are 10 and older. But many of them die as kittens or before age 2. I have lost 3 so far-- at 18 months, 3 years, and 4.5 years. I have two around 4 and one around 6 still with me at home. Basically, it varies a lot, but it is more common for them to die fairly young than to live past 5 or so.
You should contact Best Friends Animal Sanctuary in Utah. They have an FeLV house. While they are often full, they are more likely to take animals from a rescue group like yours than from individuals. They might be willing to do a trade-- take your two positives if in exchange you take 2 or more adoptable animals from them to adopt out in your area. For instance, if you take 4 adoptable cats they might take your two positives. I would check ASAP. Michelle
