How old is a chipmunk 22 with a serial number17455?

The age of a chipmunk cannot be determined solely by a serial number like "17455." Typically, chipmunks have a lifespan of about 2 to 3 years in the wild, although some may live longer in captivity. If "22" refers to the age of the chipmunk, then it would be exceptionally unusual, as it far exceeds the typical lifespan of the species.
