Yeah I was pretty upset when I learned he had it. I think a lot of people don't realize it's out there and common.
So neutering isn't just to prevent street kittens but could help reduce the infection rate.
There are other viruses that are pretty bad for cats. Like the lukemia one. I'm not sure if it's transmitted the same. But probably since it's a virus.
There is an adolescent male with a collar on that comes up to my porch some times.
I've been trying to figure out who the owner is. Let them know that local outdoor cats around the neighborhood have FIV. They need to get him neutered and should honestly keep him inside.
