The Felinea Virus is a contagious pathogen that transforms humans into neko cat girls. It alters their physical appearance, behavior, and even some aspects of their physiology. Spread through bodily fluids and airborne particles, it causes flu-like symptoms before gradually manifesting distinct neko cat-like features. Infected individuals experience enhanced senses, behavioral changes, and altered physiology. Currently, there is no cure, but research is ongoing.
