Have you ever wondered how old your cat was? There is an updated formula which replaces the outdated 7 human years per cat year which provides a more accurate assessment of a cat’s development. The first year of a cat’s life is equivalent to 14 human years, the second year is equivalent to 10 human years, and every year thereafter is equivalent to 4 human years. For example, a 18-year-old cat would be equivalent to an 80-year-old human.

In recent years, feline life-stages have been redefined as well to more accurately reflect their growth and development over the years. Kittenhood is defined as the period from birth to 6 months of age, a junior is between 7 months to 2 years of age, a young adult is between 3 to 6 years of age, a mature cat is between 7 to 10 years old, senior cats are between 11 to 14 years of age, and super senior or geriatric cats are 15 years old or older.

Mixed breed cats tend to live longer than purebred cats, with an average lifespan of 14 years compared to 12.5 years for purebred cats. The most common cause of death in cats over 5 years old is kidney disease, with over 13% of cats succumbing to kidney failure. Out of the 13 cats I have had over the span of 37 years, three of them passed away as a result of kidney disease, so I am acutely aware of this statistic.

However, I met two cats in the past who beat the averages, with one cat at 25 years of age, and another who was a ripe old 29 years of age. Both cats were extremely frail and only had the energy to sleep, eat, drink, and take care of excretory functions, but it was impressive to see that they were still alive at such advanced ages.

Supposedly, the oldest cat was Creme Puff, who lived 38 years, from August 3, 1967 until August 6, 2005. There are several cats who are still alive at this point, the oldest of whom is Great Grandma Wad who is 36 years old. The oldest cat who is still alive who was verified by Guiness Book of World Records is Flossie, who was born on December 29, 1995.
