For every year of the cat's life after age 2, one cat year equals approximately 4 human years. This is based on how cats mature - for example at around 10 - 11 human years most cats start to slow down quite a lot... This is when they're getting to about 60 years old in Kitty terms.
At 14 cat years old, an indoor only cat would be 72 human years old, an outdoor cat would be 120 years. This rate of aging kicks in around the 3 year mark. Whether indoor or outdoor, a cat ages a lot the first 2 years. When a cat is nearly 1 year old, they are approximately 15 human years old. When the cat reaches 2 years old, he is approximately 24 years old. An indoor cat will age approximately 4 human years for every 1 cat year and an outdoor cat will age approximately 8 cat years for every 1 human year.
