The oldest mouse ever is Patrick Stewart (USA, b. 14 July 2013) who was verified as being 9 years 180 days old on 10 January 2023 at the San Diego Zoo Wildlife Alliance in San Diego, California, USA.
Pat’s age is unprecedented for a mouse. He’s almost two years older than the previous oldest mouse ever recorded, Fritzy (1977-1985), who was owned by Bridget Beard (UK) and lived to the age of 7 years 225 days.
Pat was born on 14 July 2013 in the Pacific Pocket Mouse Breeding Facility at San Diego Zoo Safari Park, where he has lived his entire life.
