Of course, I had to add this to my “cat lore” at once. The patterns are obtained by carefully shortening the hair, revealing the darker color unerneath, or by cutting the hair altogether exposing the pale skin. I’d imagine this would be more common among catfolk who have a monochrome fur coat, without many spots and such.
Aside for that, not much to say about this sketch. Just two Ajshari warriors resting a bit after some training. In general, every Ajshar male is forced to serve in the army for roughly three to five years depending on the country, and some choose to remain full time in the army even after that. That generally means a high pay and a high status, and in case of death their family would still receive a regular payment. Also, you can expect more art of these “pattern cats”.
