I have a couple new arrivals I've been trying to trap and have fixed. I notice that one of them has become very thin the past couple of weeks and he/she has also become friendly we me all of a sudden. I've had FelV show up in my colony before so I was wondering if I have them tested and it comes back positive what should I do? I have 5 outside and 8 mostly indoor cats. The indoor cats have been vacatinate for FeLV and I understand it is only 80% effective.
