I think personality just depends on the cat. I've had both male & females over the years. Currently, I have two of each. The tabby female is a love sponge. If we could hold and cuddle her 20 hours a day she would ask for more. The calico female is cold, aloof and fearful. The longhair male was cold and aloof until he was about 2, now he is very interactive, but less cuddly than the female tabby. The shorthair male (male litter-mates) is the alpha male and is agressive and somewhat affectionate and loving, but in a different way than his brother.

My theory-it just depends.
