Brachycephaly is a mutation characterized by a broad, shortened skull, often paired with bulging eyes and/or teeth that don't quite fully fit in the mouth! (Persian cats and pugs are a perfect example of this.) I was thinking it could be nifty to have some snub-nosed lions ingame!

-edit-
Since brachycephaly effects the airways by shortening the nasal passages, this could also effect how they hunt/patrol! Females could have a shortened amount of hunting turns, and males can take fewer steps while patrolling! (suggested by #157507)
