Which rodent is commonly found in California?

The house mouse is one of the most commonly found rodents in California due to its adaptability to human environments. This small rodent is often spotted in urban and suburban settings, where it can easily find food and shelter. Its ability to reproduce quickly and thrive in close proximity to humans contributes to its widespread presence.

In contrast, the Norway rat and roof rat are also significant rodent species found in California, but they tend to be more associated with specific environments, such as sewers or agricultural areas. The woodchuck, or groundhog, is not typically found in California, as it is more common in the eastern and northern parts of the United States. Each rodent has its habitat preferences and behaviors, but the house mouse remains prevalent across California due to its resilience and close association with human structures.
