Well, if I woke up and found aliens had stolen my nutsack, I wouldn’t go out anymore either.
LOL! The neutering thing is always something of a moral dilemma for me. But we couldn’t keep him unless we did it (we lived in an apartment at the time, no yard) and he had been pretty badly injured by a car, which was why we took him in in the first place. Unneutered toms are simply not fit to live with indoors. (IMHO, of course.)
