Erin's Cosmetic Genes

A large pack of purely cosmetic genes for you to mix and match to your hearts content! They also automatically switch colour if certain fur genes are detected! Currently only the Anthrosonae and Auraeyl.

More content may be added at a later date depending on requests and my own motivation. Keep an eye out!

Currently 31 purely cosmetic genes including ears, tails, and horns!

Check the preview images to see them all! There's far too many to list here.
