I like the detail that the cats in warriors only have words for direct family relationships and only refer to any relative more removed by a chain of those direct relationships. It can suggest how the cats' society views family relationships and how important (or not) they are in the clans. Direct relationships are special, or at least noteworthy enough to have their own words. Beyond that you're just vaguely family. It's maybe a fun detail to share the chain of how you connect, if you know it, but it isn't anything more than that. Ultimately you're all clanmates, which matters more to them (or is supposed to), so tracking families beyond one relationship away isn't useful to them at all. The way the cats act in canon sure seem to fit this sort of interpretation, anyway, I think.
