Calculate Your Cat’s Years to Human Years

Trying to figure out your cat’s age can be a very frustrating exercise. If you have adopted a cat or taken in a stray and wondering how old your feline pal is in human years, then this article is for you. It will help you convert your cat years to human years.

A common misconception is that one year of a cat’s life is equivalent to seven years of human life. In fact, a cat’s aging is a lot faster during the first 2 years of its life. Cats reach the estimated human age of fifteen years during their first year, and then 24 when it is two years. After that, each cat year is about four years of each calendar year.

Although there is no reliable scientific method to calculate the relationship between cat years and human years, it is generally accepted that the first two years of a cat’s life are equal to the first 25 years of human life. After that, each additional year is approximately four cat years.

One thing to consider when converting your cat’s years to human years is early maturity. For example, the way humans developed to have long gestation periods, which also include longer periods of childcare and intensive rearing. Domesticated indoor cats have just 66 days of the gestation period and give birth to a kitten that needs only a small fraction of the type of care and attention that human babies need.

This is the reason why a one-year-old kitten develops equivalent to a 15-year-old human, and the physical maturity of a two-year-old kitten is almost equivalent to a 25-year-old human. Then, for each year after the first two, each year is approximately four human years. This makes a 5 years old cat equivalent to a 37 human years.

A well-exercised and well-fed indoor cat will likely live longer than many indoor and outdoor cats. While indoor and outdoor cats will live longer than stray and feral cats. Nowadays, the average cat lifespan is approximately 14-17 years. Although there are some who lived up to twenty years and beyond. According to the Guinness Book of World Records, Creme Puff is the oldest cat ever. She was born on August 3, 1967, and lived until August 6, 2005.

It is worthy to note that a cat that lives outdoors ages much faster, maybe twice faster than an indoor cat. Outdoor cats can have a much shorter lifespan than indoor-only cats, which often live about two to five years. Cat owners in urban and suburban areas are strongly advised to keep their feline pal indoors.

Cats are generally long-lived, although mileage varies according to genetic predisposition and owner maintenance. In some documented cases, cats have surpassed 30 years in age. In general, indoor cats can live 12 to 18 years, and many lived to their 20s. Therefore, a 5 years old cat would be about 37 human years and a 21-year-old cat will be approximately 100 years old in human years.
