Catgirls have had a symbiotic relationship with humans since time immemorial. Many young men long to become breeders, humans who are responsible for quelling a catgirl’s lust when they go into heat. Chris Redford was just a normal college student attending San Diego University for his PhD in Catgirl Physiology and Medicine to become a catgirl doctor, but when he runs across an abused catgirl, Chris will find his purpose in life shifting to accommodate his new responsibilities. He may also be forced to confront the darker side of humanity when he learns about what happened to Silva, the young catgirl now in his care.
