Cat years to human years

Cat years to human years

New-born kittens reach adolescence at a rocketing rate, making it hard to keep track of their actual age. How many years old is your cat, and how to calculate into human years?

Cats go through various changes as they grow up, and it can be hard to recognise at what point in their life they have reached based on their behaviour. Knowing your cats' biological age will help you understand why they act as they do. For example, when your kitten is 6 months old, it will have reached the equivalent of 10 human years. And by the time your cat is 1 year old, it will have the biological age of 15 human years.

In other words, a 1-year-old human baby will still behave like a baby. But a 1-year-old cat will act like a teenager.

Cat years to human years | 'Will my cat be 100 cat years old after only 5 human years?'

No. Cat years rapidly increase when they are kittens, and then the rate of their biological age-growth slows down as they get older. A cat that has reached 6 human years will be 40 years old in cat years.

Cat years to human years | Cat years are difficult to understand; how do I calculate my cat's age?

It is hard to calculate cat years. lilcat has investigated the topic in the name of science. The result is a table that maps out the cats' biological age for you. You can also see how many times faster the cat ages compared to humans and how it slows down when they get older.
