We don't have specific decors for mutations, it is a known fact and it is perfectly understandable.
What we do have is decors for poses - and that is what I want to use for that suggestion.

In my opinion felis females are a bit of trouble - you want them to look pretty, but all the decors are... Out of place. Nepheline wings looking like the Heaven's experiment reject are one of the things that made me think "maybe for decors felis should be coded as kind pose, so some of the decors can fit".
It wouldn't cost more time of our artists and require not as much coding as it could if we were to look up every decor version and code it for felis.

Tl;dr: Match the mutation with the closest pose in code, for example:
Primal (felis) -> Kind pose

Why I didn't make this only "felis decor tweak"? Because I have not checked other mutations and how should they be coded in the term of poses, so if you guys think one of the mutations should be better in another pose, let me know in the comments!
