Burrowing, nesting, and hoarding are species-typical activities that mice readily perform in the laboratory. This article describes how they can be easily and cheaply assessed. These protocols are extremely sensitive to mouse strain, brain lesions and diseases. Moreover they constitute “environmental enrichment” for the mice, and embody the “Refinement” aspect of the “3 Rs”18.

FAQs
The measured behavior does not map to a single biological process. Reduced removal may indicate diminished motivation, impaired motor performance, or poorer well-being, so the result is informative but not self-explanatory. This distinction matters when comparing animals or interpreting a phenotype: a low score should be treated as a signal requiring additional behavioral evidence, not proof of one specific deficit.
Substrate choice and presentation are central experimental variables. A typical arrangement places food pellets or another loose substrate inside a tube, giving the animal material it can displace. Researchers should keep the container arrangement, substrate type, and testing duration controlled across conditions because the assay's value depends on comparing removal under equivalent testing circumstances.
Complementary behavioral measures help separate motivation from movement and general condition. If burrowing falls, parallel observations can help determine whether the animal is less willing to engage, less able to perform the digging action, or showing reduced well-being. This interpretive approach is especially important in biology studies where several changes may produce the same reduction in removed material.
The assay focuses on an innate tendency rather than requiring animals to learn a complex task. That feature makes the readout useful for detecting changes in naturally expressed behavior, while still leaving open which biological function has changed. Investigators can use the amount displaced during a defined period as a functional behavioral outcome alongside broader phenotype characterization.
A basic workflow uses a tube filled with food pellets or another loose substrate, places it under controlled testing conditions, and measures how much material the rodent removes during a specified interval. Consistent timing and setup are important because the assay compares displacement across animals or experimental groups. The resulting quantity provides the primary behavioral measurement.
Biologists and neuroscientists apply the assay to characterize phenotypes associated with neurological disease. It can reveal whether affected animals show altered performance in a motivated digging-related behavior, adding a functional dimension to disease models. Because the measure is behavioral, it can complement broader biological observations rather than serving as a standalone description of neurological status.
Treatment studies can use burrowing performance to evaluate whether an intervention changes a functional behavioral outcome. A difference after treatment may indicate altered motivation, motor performance, or well-being, but the assay alone cannot identify which explanation is responsible. Pairing the result with complementary behavioral measures improves interpretation and helps distinguish a broad functional effect from a specific behavioral change.
