This is a fanart for my wonderful friend AstroGriffin's beautiful graphic novel "The Breathing Ridge"! If you love stories that focus on animals, I urge you to check it out! She posts a new page every Friday on DeviantArt and ComicFury:

On the left is the story's protagonist, Yuxin, who is a ferox (a species of carnivorous non-mammalian synapsid endemic to the world of the Breathing Ridge).

On the right is Amice, who is a type of large cat called a gigil.
