I have had 2 males cats before, first one was a rescue and didn't really have time for me but cuddled my other half. Second male had wobbly cat syndrome and was a mummies boy.
I now have 2 females and I always thought they were aloof and not affectionate, but I was wrong, Bella is a snuggle bug and loves cuddles, all the time and she is so friendly and likes everyone. Rosie ignored us all the time and would run away from us, however other the last couple of months she is now my best friend, she comes in and chills with me in the couch, loves cuddles and she likes it when I hold her paw.
So I would say based on the cats I have had, females are more loving.
What's everyone else experiences?
