Ratbats were a non-sentient species that lived on Despayre, a prison world in the Atrivis sector of the Outer Rim Territories. The ratbats were caught by the prisoners working on the surface of Despayre and roasted, contributing to their meager diet. All the ratbats on Despayre perished with the destruction of the planet by the first Death Star that occurred in 0 BBY.
