Try looking for a FIV cat
It's a cat with the feline equivalent of the HIV virus. These cats turn up an awful lot in rescue centres, as once they've got FIV, they can only be around other FIV-positive cats.

Chances are you won't get a kitten, but rescue centres would be very pleased to let an FIV cat go to a good home, and I think they're ok with letting them go to a place without outside access, simply because it then won't come into contact with other cats, and therefore won't pass the virus on.

Try cat's protection league, I think they're meant to be quite good.
