This sounds like my area of expertise!
the lowdown. A couple hundred gigacycles ago, scientists figured out
the secret to genetic modification. After a couple cycles of tragic
accidents and poor standards, they perfected the process - it became a
standard of society and all.
Just a hundred gigacycles or so
ago, some crazy fuck decided to see what would happen if they went in a
more radical direction - he gave some poor sap gills (the guy promptly
suffocated.) This nutjob was loose for a while, mutating random people
in some sort of vigilante experimenting process. He was eventually
caught, but his research stayed on - and that's when the first
neo-furry was born. Guy spliced himself with a tiger, he grew fur and
claws and shit.
Before long, it was common practice among
certain people to splice yourself with animals, because they knew it
would just be an easier way to create the drama they needed to survive.
Eventually, the governmental collective decided "enough is enough" and
made it legal to hunt these fuckers down - they were making a mess of
society and humanity, not to mention making humanity look really
fucking awful to the rest of the universe!
Now we've got
government-sponsored hunting year-round, with bounties on particularly
annoying or notorious neo-furries. It's quite a lucrative business,
most people hunt 'em for a living.
