Hello I have a 3-4 year old male cat and I believe he is lonely. I have had him for 2 years now and over the past month or two it would seem as though he is lonely. There are two people in my apartment and he was always more attached to the other person living here however he now comes to me for attention. From when he was born to when he was 1 or 2 he lived with two other cats his sister and his brother. Does he need to live with other cats because of this reason? The previous owners said it seemed like he didn't like it much but still. Thanks!
