British rabbit owners Mike and Irene Womack believe their rabbit Hazel holds the record for World’s Oldest Living Rabbit at the age of 16. Currently, the title is held by George, a 15-year old rabbit from Massachusetts.
According to Mike Womack, “Our granddaughter Charlie brought him home when she was six years old, and she will be 22 this month, so he must be 15 to 16 years old.”
Before a new world record can be declared, Hazel’s age would have to be verified by witnesses and vets.
