Peromyscus eremicus
Mouse (Cactus)


They are found in Texas.


They live in the desert in rocky areas among cliffs.

Body Traits

They can reach 7 inches long (180mm), with their tail making up 4 inches of their length. They are dark colored with long hair and large ears.


They are great climbers. They go up trees to feed on seeds and climb cliffs to escape prey. They survive very hot temperatures by going into hibernation (aestivation).


They eat plants, seeds, beans, nuts, and insects. They don’t need to drink water to survive as they get enough moisture in the things they eat, but after a rain they drink!


They are eaten by hawks, coyotes, foxes, bobcats, and weasels.
