Coastal Colony
Cats that live near the ocean, or as they call it, 'The End of Beyond'.
They use the tidepools to communicate with their ancestors and can be seen decorating their pelts with bioluminescent algae for their 'celebrations'.
They tend to eat more fish, are fast swimmers, and have a new role called Current Chasers, whose job is to keep an eye on the strength of the tides and rivers and teach kits to swim and dive.
