i feel guilty, but i'm not going to try to talk you out of this, quite the opposite! with apologies--

it's entirely possible that this little black guy will settle down after neutering, and with a little extra special tlc for all concerned and a careful introduction, i bet he would work in nicely with your kitties. i have 7 black neutered males, and they seem to be the lovingest and most laid back of my herd. all of them love kittens--Omar, Midnight, Tissot and Foo Foo actually let them suckle. they're real daddy cats! Omar in particular has been a godsend with feral kittens--a couple hours with him and they are so gentle. he's a miracle worker. Midnight had been a farm cat all his life, though neutered since age one, and adjusted quite well to a life indoors starting at age 11. all these black kitties have a fine sense of humor, too.

i share your concern about black cats and Halloween.
