The 2010 Guinness Book of World Records lists Cream Puff, a cat owned by an Austin, TX man named Jake Perry, as the oldest cat to ever live. Cream Puff was born on August 3, 1967 and died on August 6, 2005. She lived 38 years and 3 days.
Perry also owned another long-lived cat named Granpa, who died after 34 years and 2 months. Most cats live an average of 12-15 years.
It's unclear why Perry's cats were able to live so much longer than average, but many suggest that the cats' diet had something to do with it. Every morning, Perry would feed Granpa and Cream Puff a meal consisting of bacon, eggs, broccoli and coffee.
Perry was featured in the short documentary "South Paws," which depicts him and his relationship with his cats.
