AWWW what a wonderful "love" story. I would definitely bring this cat in but take some precautions first.
You indoor cat only needs to have an updated distemper vaccine and rabies (if county required only). I would not give the FeLK vaccine. There is much risk IMO involved in most vaccines. You can google "vaccinosis" to get more information about vaccines and the effects on our pets. It is a money making business also for drug companies and vets. After most initial dosing's as kittens and puppies, they are immune for many, many years.
Make sure when and if you decide to bring in the feral, take him directly to the vet from the carrier, have an appointment already set up. If he is not neutered, then get that done too. Have him tested for FeLK/FIV and all of his shots. Wormings and flea preventative as well. When you do bring him home, have a separate room for him to stay for a couple of weeks to make sure he healthy before even considering introducing him to your indoor cat. He will have worms, I am sure, so you want to make sure he is worm free before you let your other cat near his litter box. Do lots of scent swapping back and forth during that first week after his two week quarantine in his room. Then he can be let out for short periods under your supervision only. I would keep him in his room at first when you are not home, at least in the beginning. As they become friendly, then you can leave him out more and more, and let your cat into his room to investigate (after a negative fecal

). Good luck and yes, cats are absolutely wonderful little creatures
