Bianca and momo are not chopped liver (love them), but they are just not as cuddly and interactive as baby Boo. Is this true of female vs. male cats in general?
I believe that in general, male cats are more outgoing and effusive. I know that Harvey is exponentially more snuggly than Samathea, or any other female I've had, to the point he often seems very demanding. But as far as interactive play goes, they both seem equally inclined to include us two-leggers in their games. As both a long-haired cat and one that had a very rough start to life therefore a bit of a spaz, Sammie does not like to snuggle. The thing is, Sammie IS affectionate and loves to play with us. Its more like, for her just being in the same room with someone says about the same for the level of trust and affection as Harvey expresses by jumping up onto your shoulders. Harvey often snuggles up with me while I sleep - lying on top of my legs, usually in some spot that makes it impossible to move or be comfortable. Sammie will sleep next to me - in summer, she sleeps on the chair next to the bed, in winter, she sleeps on the bed. She usually spends about three minutes kneading her claws and purring oh, so softly then moves away to her spot. It's very comfortable and companionable. Harvey wants to be held for hours at a time. Sammie won't stay still in my arms for more than 20 seconds except at the veterinary clinic. Harvey paws at my leg when he is hungry or wants me to play with him. Sammie sits in my line of sight and stands up on her hind legs, which if caught on video would cause many people to be utterly ded of teh cyute. I see Sammie as comfortably affectionate, and Harvey as overwhelmingly so. The differences you note in your cats may well be sex differences combined with personality differences, informed by life experiences.
