My elderly neighbor came to me yesterday and wanted to know if he thought he should get a cat or a dog. He is a widower and very very loney. I just worry about his ability to take proper care of an animal......he has no family to speak of and he just wants something for companionship. I couldn't stay to talk to him about it because I was on my way out, but he says he will talk to me about it again tonight.........what do you guys think I should tell him?
