I don’t think so
Viewing post in Kit to Leader: 8 Year Anniversary comments
Well, like... You can adopt kits with her! But you need to be her mate, so when she's an apprentice, catch 20 preys then talk to after, when she asks to go to the beach with you, say yes, then accept being her mate! (must be female for this to work). When you become leader and defeat Firestar, when you talk to her about becoming FireClan's new leader, say yes to meeting up with her, then after talking to her enough, go to FireClan and she'll talk to you about Ryeheart being your father, him saying "I have no kits." -- yeah, yeah. Leave and then return, click on her, she'll look upset, then she'll say she's found 2 kits on the territory and their parents are nowhere to be found, when she asks if you wanna adopt them with her, say yes, she'll let you name them, and then you've officially (kinda) got kits with Breezesong/Breezestar! And yes, they do grow up! You can't choose their suffix; it'll randomly generate one for them both.
