The laboratory mouse or lab mouse is a small mammal of the order Rodentia which is bred and used for scientific research or feeders for certain pets. Laboratory mice are usually of the species ...
For example, researchers have found that many rats and mice in laboratories are obese from excess food and minimal exercise which alters their physiology and drug metabolism. [30] Many laboratory animals, including mice and rats, are chronically stressed which can also negatively affect research outcomes and the ability to accurately ...

[1] It is the main federal law in the United States that regulates the treatment of animals in research and exhibition. Other laws, policies, and guidelines may include additional species ...
Species of rats are found throughout the order Rodentia, but stereotypical rats are found in the genus Rattus. Other rat genera include Neotoma (pack rats), Bandicota (bandicoot rats) and Dipodomys (kangaroo rats). Rats are typically distinguished from mice by their size. Usually the common name of a large muroid rodent will include the word ...
