It is difficult to accurately estimate the total number of mice in the world, as they are found in a wide range of habitats and environments and their populations can fluctuate significantly over time. In the scientific setting, the term “mouse” refers to any of the 38 species that belong to the genus “Mus”.
These species are small, usually weighing under 30 grams and measuring less than 12 centimeters. Mice, as mammals, are closely related to rats.
Are Mouse and Rats the Same?
Rats and mice are both rodents, and though they share some physical traits, they differ significantly. Rats are larger and heavier. Mice have smaller, slender bodies, while rats are bulkier. Learn more.
Another key difference is their tails. Mice have long, slender, hairy tails. Rat tails are shorter, thicker, and hairless. These size and tail differences help distinguish them, though there are other physical and behavioral markers too.

Habitat and Distribution of Mice
The 38 species of the Mus genus are native to Eurasia and Africa. These mice thrive in various habitats, from lowlands to mountaintops.
Mice are adaptable animals that can live in forests, fields, and urban areas due to their ability to thrive in varied environments and climates.

Reproduction and Life Cycle of Mice
Female mice are receptive to mating every 4 to 5 days. If they conceive, they give birth to pups about three weeks later.
Mice reproduce rapidly, with a single female birthing 6 to 8 pups up to 10 times a year. This high reproduction rate leads to dense populations and quick repopulation in areas where their numbers drop.
