Three years have passed since humanity was dealt its biggest blow and all females were transformed into animals. From newborn babies to 100 year old senior citizens, there was no longer a single female human left. Panic occurred immediately in not only did love ones get transformed into beasts, but the fate of humanity was suddenly in the balance. Without females, humanity would cease to exist within the next century. Scientists quickly tried to to find solutions, with no success as of yet.
Things began to change drastically worldwide. The women that were transformed still had human intellect and memories despite smaller brain capacities.

These people became very popular with the men that wanted to remain straight. In fact, many transsexuals became prostitutes (which was also legalized) and became millionaires out of it. Due to the huge money they made, many men underwent sex change operations just make good money. Of course none of them could get pregnant although that was a process scientists were working on.
It seemed humanity was doomed to extinction. Until a lucky someone found the animal ring...
