Well, let's see...I have two males and 6 females. The females tend to be cleaner and pay more attention to what is going on around them. The males on the other hand, marking territory seems to be the only thing on their mind. When I want to go in, it is suppose to be now, not try to mark every blade of grass on the way into the house. The girls just run in, they are sometimes distracted by the last time the boys past this way, but usually not, they just want to get inside where it is warmer. Now don't get me wrong, I really like my boys, but if I had to chose, I would chose a female over a male. Sorry Guys....
