Ventral (belly) surfaces whitish-grey or yellow, usually uniform but may be finely speckled with black. Throat whitish-grey, usually finely speckled with black.

Note: trapping that removes larger predators such as weasels, ferrets, stoats, and cats has the potential to increase the population of mice, which can have a devastating effect on reptiles and invertebrates.
