The cat people army members posing in the imperial city, They seem like the pre-disapora Roman descriptions of blue painted picts and may fight nude, but the reason is quite different. At home also they only wear a few things given to them and if they do not lose them somewhere they will keep them until they are ragged and tied on with strings. They may look almost human but are an extreme modification of the human genome, they do not age and can regenerate from most wounds without a scar, hey can even regrow limbs,They are as intelligent as most sentient species and on this pre-industrial world are becoming the largest group. They live in communal clans often all in one huge room, cave or castle. Their army is multiple clans combined. Male cat people are rare, I've never seen one, and cat people may also have parthenogenesis.
