I have both male/female. Close to 1 year apart. They're both affectionate but if I had to pick one, I'd say Zoey's the more affectionate one. Also the more "mama's girl". Basically, she doesn't care of anyone (human & non human) except her pack (my parents, me, her fur brother). But even within our "pack", she favors me the most. Along with it, comes affection.
My mom gets bit jealous sometimes. lol
