Why You Sometimes See a Mouse on the Street
Mice venture onto sidewalks primarily when their usual food sources become insufficient. Urban environments present gaps in natural foraging areas, and rodents respond by seeking alternative supplies in human‑occupied spaces. Factors that drive this behavior include:. Date latest changes:
Do Mice Fear the Smell of Cat Urine?
Mice rely on an acute olfactory system to locate food, identify conspecifics, and detect predators. Olfactory receptors in the nasal epithelium bind volatile compounds, transmitting signals to the olfactory bulb and higher brain centers that trigger instinctive responses.. Date latest changes:
Which grass mice dislike in the garden
Mice in garden ecosystems rely on a limited range of plant material, seeds, and insects to meet their nutritional needs. Their foraging behavior is shaped by the palatability and chemical composition of available grasses. Species that contain high concentrations of silica, bitter alkaloids, or dense fiber are typically avoided, reducing their value as food sources.. Date latest changes:
