Fayse belongs to a Norwegian subset of fae-folk referred to as Fairy Cats

Fairy Cats are a surprisingly peaceful race of fairies that have the ability to shapeshift into whatever they can establish eye contact with; some Fairy Cats are better at this than others

Fayses shapeshifting abilities are less than stellar, being only able to shift his head and no other part of his body; this has led to a lot of horror stories about "human faced cats" walking around in the snowy forests.
