The life of a grey squirrel is variable. Some die within a year or two, yet others live for up to 10 years. The typical life however is more like 4 to 6 years for females and 2 to 3 years for the males
A lot of mean comments on here - grey squirrels didn't ask to be 'introduced' into our country. They were probably quite happy where they were ! And, what's the biggest vermin, a rampant phaedophile, the monster who murdered that 93 year old lady or the scum who beat and starve animals ?? Give me squirrels any day of the week !
