I get the concern about outside cats (even if I don't entirely agree with it), but at the same time, my only choice with this guy was to put him outside or take him to a shelter, where it's likely he would've either been returned, been put down, or ended up outside anyway. It was clear he did not want to be inside. He's a great cat, but he responds to being trapped inside by marking and nervously shredding everything. He's fixed, on flea meds, fed twice a day, and has shelter. Even outside, he tends to attack our legs. I did not want to put him outside, but a friend who works at a shelter relieved my mind by pointing out I basically neutered and released a feral cat, which is not a bad thing.
