I have always preferred females over males because of what I'd heard about the marking, but ever since I got Kalani I have totally changed my mind! I absolutely love my little boy - he is such a little cuddler and very smart. I had him neutered at 5 1/2 months before he started any marking behavior and he was way easier to potty train than my female
He does like to lift his leg to pee sometimes but I have one side of the potty pad up against the wall and that is the 'only' place he will lift his leg.
Good luck on your search!
