Is there a difference in personality between males and females?
No more so than there is in people. There is a wide diversity of personalities in dogs. Each puppy will have its own unique personality which was formed in the early stages of its rearing. The genes a puppy inherits from each of its parents and the environment in which it was raised both play a role in personality development. Traits like dominance, bonding, trainability, aggression, shyness, etc. are not sex linked, and so will not appear exclusively in males or females.
A. Of course this is only my opinion and other breeders may disagree, but I firmly believe that the male kittens are more mellow and affectionate. Whenever I have a favorite kitten in a litter, it is almost always a male! I can also honestly say that in my experience with multiple-cat households, multiple males get along better than multiple females. The females tend to be more territorial and ‘bossy’. I get several requests for females, and when I ask why they prefer a female, lots of people answer that they “have always had females”, or they have heard males spray (see next question), etc. Due to the fact that I will always have more males available than females, I suggest being flexible when it comes to choosing a gender.
