This is Spotless, a character from my NaNoWriMo story. He's a creature known as a Wirrsa - a canine/feline hybrid. In this case, he is a king cheetah/jackal mix.
Spotless is part of a small and upcoming pack of five, in which he is the only other male and the younger brother to the pack leader. Spotless lives up to his name when it comes to his coat, having been born with a rare genetic mutation that kept his coat free of markings. The only exception to this is the black tear marking that all the cheetah/jackal wirrsa possess. He is a very serious character who is often pointedly rude towards those he doesn't know.
