Rescued a very friendly stray neighborhood 2 yr old male cat july 2020. He is very loving. Not a lap cat but snuggles. Plays well. But still wants to go outside, made him an indoor only cat. So many questions, should we let him go back out? He has 3 windows he sits at all day. Should we get another cat or dog for companion? We are a couple in late 70 s. He eats well. Naps frequently. Wanted to sit at an open door even in winter!
