Having reread this thread a bit...
We have 7 ferals, OP. Of our 9 house cats, 2 are semi-feral and come in and out of their own accord, and of the 5 remaining shed cats, they eat in the sheds and then bugger off out again and they are also semi-feral and "wild", with the personalities you describe of your BF's cats.
However, my caveat to that, is that I am very, very experienced with ferals and semi ferals, am used to dealing with them and have the space, time and inclination to actually be able to and more importantly, want to deal with them.
It sounds to me, like it is a management issue and your BF is not listening and coming to a compromise with you. Personally, I think that you are being a little hysterical because of my extreme pro-cat bias, BUT I also see your point of view, and I can see that your boyfriend is not helping matters by helping a) address your concerns and b) coming to a compromise with the cats.
It sounds like the cats are totally under socialised and are not domestic pets at all. I would suggest to the BF that at the very, very least you need to have cat free zones in the house. Then ask your BF to put up a shed, with a cat flap in to it, that is warm, dry, sheltered, with bedding and somewhere you can feed the cats outside with good shelter. They won't die, they'll probably adapt pretty easily. The secret to happy outside cats is a really reliable food source and very good shelter that they are happy to and like to use.
