Like their wild cousins, house mice occasionally have which of the following?

House mice typically exhibit characteristics similar to their wild counterparts, and one of the most prominent features is the coloration of their fur. Wild mice commonly have gray or brown fur, but their bellies are often lighter in color, typically white or even cream. This lighter coloration helps them avoid predators by providing a form of camouflage against the ground.

The belly's white fur is a significant characteristic that differentiates house mice from other rodents and is particularly relevant when identifying these pests. The lighter belly also serves a functional purpose, as it can reflect less light, helping the mice to remain inconspicuous while foraging or moving about in their environments.

In contrast, the other options present different features that are either not specifically associated with house mice or pertain to different species. House mice can have varying shades of fur, such as gray or brown, but their notable white-furred bellies are a consistent and identifiable trait across both wild and domestic varieties.
