Where to Listen to Mouse and Rat Sounds
Rodent vocalizations provide insight into social hierarchy, predator avoidance, and reproductive status. High‑frequency squeaks typically accompany aggressive encounters, while low‑frequency chirps often signal affiliation or maternal care. Recognizing these patterns allows listeners to infer the underlying behavior without visual observation.. Date latest changes:

Rat litter: photos and features
The gestation period for rats averages 21‑23 days, with slight variation depending on strain and environmental conditions. A single pregnancy can produce anywhere from 6 to 14 offspring, and females are capable of conceiving again within a few days after giving birth, allowing multiple litters each year..
