Synopsis: Chart and calculator provide quick conversion of a cats age in years to an approximate equivalent human age. Cats age much more quickly in their first two years of life and then the aging process slows down and continues more steadily in that for every human 2 years, each cat year equals approximately 4 human years. On average, indoor cats may live from 12 to 18 years, and many even survive into their 20's.
Unlike dogs - who have different human age equivalents depending on their size - the conversion method for cat to human age is universal because cats are all roughly the same size. However, when comparing cat years versus human years there is no "true" mathematical formula. Nor, does one cat year equal seven human years as the age of a cat does not follow a linear curve compared with human age.

Like many other animals, "childhood" and "adolescence" occur much faster than in humans. Kittens, when compared to newborn babies of human, grow very fast - especially in their first 6 months - before reaching puberty at about 6 to 8 months old. When they reach the age of 6 to 12 months, you can consider them to be the equivalent of at least 10 human years.
Cats age much more quickly in their first two years of life and then the aging process slows down and continues more steadily in that for every human 2 years, each cat year equals approximately 4 human years. Veterinarians generally agree that the first 2 years of a cat’s life are roughly equal to the first 25 years of a human life.
Keep in mind that felines who live outside (outdoor cats) tend to age far more quickly - sometimes twice as fast - than an indoor cat. On average, indoor cats may live from 12 to 18 years, and many even survive into their 20's. Whereas outdoor cats face greater threat of accident and/or illnesses, and average around 10 years of age.

How to Tell a Cats Real Age
Veterinarians can tell a cat's true age by studying their:
- Blood work
- Body condition
- Medical history
- Teeth and gums
- Physical examination
Cat Life Stages
There are considered to be six stages of life for cats:
|The Six Stages of a Cats Life|
|Kitten||0 to 6 months||The young cat is growing rapidly and is usually not quite sexually mature.|
|Junior||7 Months to 2 years||The cat reaches full size and learns about life and how to survive it.|
|Prime||3 to 6 years||The cat is mature physically and behaviorally, is usually healthy and active, looks sleek and shiny and making the best of life.|
|Mature||7 to 10 years||The cat is what we call "Mature", the equivalent to most humans in their mid-40's to mid-50's.|
|Senior||11 to 14 years||The cat reaches the equivalent of around 70 human years.|
|Super Senior||15+ years||Many cats will reach this stage, some do not show signs of being so old.|
