In the Guinness Book of World Records, the oldest cat is 34-36 years old. In human years, a 30-year-old cat is over 130, and a 34-36-year-old cat is between 150-160. Typical Indoor Cat Lifespan. If a cat resides indoors exclusively, the typical lifespan ranges somewhere between 13 and 17 years, according to the ASPCA. However, it isn't uncommon for indoor cats to live to at least 20. The lifespan always depends on the individual cat. Some cats pass away well before 13, while others live long past 17. Today cats live longer than ever.
