Because they have to deal with the males ignorance..and you.
Because male cats don't want to be called pu... nevermind.
because the male cat is male and the female cat is FEMALE
Same reason male and female humans are that way I guess.
My roommate's male cat is seriously like the Ted Bundy of cats. ******* sociopathic bastard.
lol male cats fight a lot(or if you only have one, are sort of dominating as in more likely to not respect personal space/personal time) and female cats are picky about things. I've never had more than one female cat at once so I can't comment on how they are with other females. Female and male cats put together are either really cute, or really funny in the lengths they go to avoid each other.
I've noticed more of a difference in temperament when it comes to the color of the cat.
I like luckypickle's answer!!
