How Long Does a Shrew Live

Shrews live a life on the fast track. Within 1 or 2 years, these small mammals go from birth to sexual maturity, mate, raise offspring, and die. As a consequence of their high metabolic rate—exemplified by 800–1000 heartbeats/min—shrews have to be almost constantly in search of food.

How long can a shrew live without food?

Water shrews can live without food for up to 3 hours, but captive shrews have been found to feed almost every 10 minutes. The amount of food required by a water shrew has been estimated to be 0.95 g/day.
