A post furryfication world

This is a base for future projects. But basically one day during the mid 2010s the majority of the world awoke to find themselves turned into ether a Furry or a Demi-human. (being called the shift) Scientist the word round were baffled by this. Scientists found that the type people became depended on in order of importance: if they had a fursona or similar alter ego, personality, whare they live(if someone lives near the ocean they are more likely to be a aquatic animal), family relations (so if your sister is a fox you will likely be a fox), personal opinions on an animal.
