Tiffany Two Tiffany Two (March 13, 1988 – May 22, 2015) was the world's oldest living cat, aged 27 years, according to Guinness World Records. This distinction is different from the oldest cat ever verified; Creme Puff lived for 38 years, 3 days.
Big Bertha (cow) Big Bertha (17 March 1945 – 31 December 1993) was a cow who held two Guinness World Records: she was the oldest cow recorded, dying just three months short of her 49th birthday, and she also held the record for lifetime breeding, having produced 39 calves. During her lifetime she helped raise $75,000 for cancer research and other charities.
