I highly recommend checking out the shop in my sig. She is great with horns but is also very good with cat and fox ears so she'd do great with your characters. She even said they sounded fun to do and that she'd probably do them within a day since she'd enjoy them a lot. An example is my sig but there are many more at the shop ^^
I'm gonna sell you my art~ ♥
