The Jaliscan cotton rat or Mexican cotton rat (Sigmodon mascotensis) is a species of rodent in the family Cricetidae. It is found only in Mexico. They commonly have brown fur with white fur on the belly. They are ground-dwelling and prefer open habitats.
The Mexican cotton rat is endemic to Mexico and is distributed along the western coast of the country. This area is located in the tropical deciduous forest biome, and the Mexican cotton rat prefers to reside in the open, grassy areas with dense areas of ground-level vegetation and little to no trees. However, these rats will occupy a variety of habitats when their populations grow in size. The Mexican cotton rat coexists cooperatively with other similar rodents in the ecosystem.
The Mexican cotton rat belongs to the family Cricetidae in the order Rodentia. While it used to be considered a subspecies of Sigmodon hispidus (Hispid cotton rat), the Mexican cotton rat was designated as its own species after an ancestral karyotype study. The Mexican cotton rat and the Hispid cotton rat can be distinguished chromosomally as well as by different skull characteristics.

GBIF citizen-science records
It is estimated from how often the Jaliscan cotton rat is recorded against all the mammals logged in Guadalajara (22 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
