- crowfang belongs to me, rosesong to ~nan~
this is assuming that rosesong is tortoiseshell under all that whitespotting. if she's genetically black (brown) tabby then all their kits will be either black or black (brown) tabbies with various degrees of whitespotting; as she is fully white and crowfang is a black bicolour it is very possible that some of their kits will be totally white too.
