its interesting but....i feel that its wrong to do that to a kitty....the poor thing should just be left alone. its not natural for cats to glow and it should prob just be left that way
i recently gotten a stray cat (milo) the sweetest thing ever! if i were you...yes definately keep him if you get the chance. a way to get him u might just need to let him warm up to you then maybe trap him lol .Good luck!
