Don't be sad. Much safer for cats to be indoors or watched closely while being out doors. If in city/burbs cars can easily kill them. In country animals can eat them. I know some here think it's dumb, but other than bringing mine out with me and only at my side I don't do it. One cat doesn't like it at all which is fine by me. She's nearly 15 so I won't complain.He's an indoor cat.
