Cats! Here's the male again, being irritated by a sassy old lady cat.
Her ear is mostly missing on this side, which is why it looks so short. Also, she's got a mane. Yep, a mane. Females of this species grow manes as well.
The lineart was really originally the sketch layer, which is why it's so thick. I liked the sketch enough to refine it as I went. Plus, I'm lazy.
