The clan members also seem to be numbered in the hundreds and we do hear a lot about exchange of members between clans, which is probably sufficient by itself.
The minimum viable population (MVP) is 50/500 according to Wikipedia. But that number increases to thousands if there is inbreeding. Treecat clans have always seemed so small to me. I always think about some of the people I've interacted with in small, even somewhat, isolated cities. Let me tell you!

I can't recall a specific clan size being mentioned - but in A Beautiful Friendship just the portion of Bright Water Clan's scouts close enough to respond to Climbs Quickly's call was "over two hundred treecats". That seems to imply that a full clan is likely over a thousand 'cats since 200ish isn't even all its scouts and scouts are a minority of even its prime age adults (then add in the kits and elders).
And we know the 'cats practice some level of exogamy, and presumably that isn't new behavior since meeting human geneticists (given how limited the ability to communicate was until very recently). The one known survivor of Black Rock clan was (now called) Sorrow Singer - a memory singer who'd been in a nearby clan's range visiting her "litter brother" who'd married into that clan. So between the clan size and some level of leaving the clan to find a mate, there probably isn't a huge inbreeding concern.
I recall that passage and assigned it to clan size, that they all responded. But that shouldn't have been the case.
Also, a species would need some sort of way to identify relatives. Two-legs have ancestry.com LOL. Other species have ways to identify relatives as well, according to my initial post on the subject.
What about treecats? Well duh. They are an empathic species with Memory Singers! The genealogy is contained in a song. It goes a little something like this ...
