I am not sure on that, but I know almost all male cats are more cuddly then female. Also on top of that, out of all cats I ever had, tabby's seem more loveable then any other I came a cross. I know Calico's and Simese cats I have met all seem to have a bad tempers and attack or growl at you.
Interesting! My parents had two Siamese (brother and sister) who were not too bad, cuddle-wise. Daisy always loved my mom though and would constantly "groom" my mom, and Java snuggled quite a bit with my dad. Java never really cared for women much!
The color of the cat has nothing to do with determining the attitudes of the cat. Like with dogs, some cat breeds are naturally more loving; however, nurturing has more to do with it than anything else.
