Rats are also associated with human dermatitis because they are frequently infested with blood feeding rodent mites such as the tropical rat mite (Ornithonyssus bacoti) and spiny rat mite (Laelaps echidnina), which will opportunistically bite and feed on humans, [57] where the condition is known as rat mite dermatitis.

Various aged naked mole-rats. The naked mole-rat (Heterocephalus glaber), also known as the sand puppy, [6] is a burrowing rodent native to the Horn of Africa and parts of Kenya, notably in Somali regions. [1] It is closely related to the blesmols and is the only species in the genus Heterocephalus. [7]
Kangaroo rats, small mostly nocturnal rodents of genus Dipodomys, are native to arid areas of western North America.The common name derives from their bipedal form. They hop in a manner similar to the much larger kangaroo, but developed this mode of locomotion independently, like several other clades of rodents (e.g., dipodids and hopping mice).

[1] It likely originated in the Indian subcontinent, but is now found worldwide. [2] The black rat is black to light brown in colour with a lighter underside.
The breeding season of eastern wood rats depends on the climate. Those in warmer climates (e.g. Florida and Georgia) can reproduce all year, while eastern wood rats in higher latitudes (e.g. Kansas and Nebraska) breed from early spring to mid fall. Their estrous cycle lasts between 3 and 8 days, while gestation lasts between 32 and 38 days. [11]
These rats form small colonies with nesting areas, a network of underground runways and many conspicuous latrines. Latrines are large fecal piles the rats deposit on protected flat rocks. [6] In some cases, researchers have found dried leaves placed around the nesting area which appear to act as alarms to warn the rats of approaching danger. [9]
