I may have some names -fake cough- Alright here we go: If female: Doli(Bluebird), Pamuya (Water moon), Pavita (Clear water), Rayen (flower), Sahkyo(Mink)/ If male: Odakota(Friend), Pachua (Feathered water snake), Pivane (weasel), Shikoba (Unisex name, Feather) or Tohopka (Wild beast)/ Theese are all native murican names btw XD
I feel like Frostfur would be a good name, but then that might be the name of a Warrior cat I'm not aware of. *never read that book series*
So for Kiswahili names (if you wanna go by fandom rules), I'm recommending: Theluji ("snow"), Frysa ("to freeze"), or Buluu ("blue").
And if you maybe want something more unique (borrowing from various languages here: Nix ("snow"), Heilla ("charm"), Testudo ("tortoise"), Zafiro ("sapphire"), or Helado ("frozen").
Hope that helps, and that you find one you like. :]
