The plains pocket mouse (Perognathus flavescens) is a heteromyid rodent of North America.

[1] It has soft silky fur and grows to be 5 inches (13 cm) long, although nearly half of that is the tail.

They often live directly underneath Spanish bayonet or prickly pear plants.

Even those caught in grain fields usually have their pouches filled with weed seeds.

Their breeding season is mainly July to August and the females tend to have 4 embryos at a time.
