Wasn't sure where to post this. I have a 3 y.o. neutered male cat and at times he seems bored even though I do play with him. I am considering getting another cat for him to play with. My question is would another male or a female be better? Would a younger or an older cat be better? My cat is an indoor/outdoor cat and I have been told by neighbors that they see him playing with another cat that is brought to the neighborhood on occasion. I'm not sure what sex it is but I am guessing a female because I know every once in a while another male comes around and they don't get along. Appreciate comments from those who can. TIA
