first of all, i know you probably can't, but i really want to have kits as a girl except both mate options in brambleclan are girls too! also, how do you get to fireclan? also, how do you become the leader?
in order to go to fireclan ( there is no mate options there) you have to be leader, talk to breezy, make her leader of fireclan, say yes to meeting up, talk a lot.
in order to become leader you have to talk to Moonheart as a warrior (she is a grey she-cat) grab the moss to lure moss-kit from the warriors den, when you see her bring her to the leader and get 80 reputation. After that, go to fireclan and kill firestar. He has 200 health
