Negligerats
Negligerats are a fictional taxon used in speculative biology and urban folklore to describe a small, nocturnal mammal adapted to neglected human habitats. The name derives from the Latin neglego, meaning to neglect, reflecting their association with derelict or abandoned urban spaces. In typical depictions, negligerats resemble medium-sized rats, about 15 to 25 centimeters in body length with a tail of similar or slightly shorter length, and they have soft gray-brown fur, sharp incisor teeth, and highly sensitive whiskers. Some variants are imagined with elongated hind limbs that aid climbing and navigating cluttered environments.
Distribution and habitat: In fictional worldbuilding, negligerats are common in urban fringe areas, ruined buildings, rail
Behavior and ecology: Descriptions typically cast negligerats as nocturnal and wary, living in small family groups.
Reproduction and life cycle: Fictional accounts commonly describe litters of 2 to 6 offspring, with gestation
