As far as I'm aware rescues will take FIV cats because it's harder to spread but FeLV can be spread just by noses touching, CP rehomes FIV cats but not FeLV, as well as most I called, I guessed it's because FIV they can live without issues just like normal cats but with FeLV, when the cat starts to go downhill it's a horrible crash and rehoming cats with FeLV means that somewhere down the line, the owner knows that they've going to have their heart broken and the cat will be in pain, no matter how short it'll still suffer a little and as I'm sure at least some people here agree, sometimes it's kinder to put the animal down if you know for certain they've eventually going to be in pain but of course at the same time you'll always think "yeah but what if it lives until it's 18 and dies of something unrelated to FeLV?" that's why this is hard for me, he seems tired and like he's given up but I also feel that if by any chance I could find someone to just love him or somebody to take and test him so my mother can love him as she's infatuated with him, that'd be great for him but the only thing I'm certain of is he can't stay here, the garden isn't big enough to have a pen installed otherwise I would get one.
But yeah, FIV isn't as contagious as FeLV, feeding bowls, drinking, litter trays, grooming, nuzzling, scratches, biting, FeLV appears to be able to be passed through every type of contact and my cats are very loving, they'd try to get to him even in a cage and it's not fair to keep them locked out of half their house, I don't want them to start stressing out, they already try to race through the door when I go through it, it terrifies me that by trying to keep them out I'm going to catch one of them in the door.
