Um, is it intentionally or a mistake that I can make dead cats mates??? I just realized I could do this...Yeah, my StarClan cat and DF cat are mates now??? Can they have kits????
you can, i consider it a roleplaying option and no they cannot have kits once they are dead. (as far as i am aware) for example if you want to roleplay it as 'these two cats were mates in life and were separated in death by their actions in life, they still meet up and the starclan border and consider eachother mates even now'
but that is up to you
