Cat years are a way to calculate a cats age in human years. The comparison between cat years and human years changes as cats grow up. Cats mature quickly in the first year of their life, and this first year is equivalent to 15 human years. As they continue to mature into adolescence and adulthood, their second year equals around 9 human years. This means that a two-year-old cat is roughly 24 years old in human years. Once cats reach their third year, it’s approximately four human years, and it carries on like this for the rest of their life. The following table shows the equivalent human age for each cat year:

• 1 month = 1 year old
• 3 months = 4 years old
• 6 months = 10 years old
• 8 months = 15 years old
• 1 year = 18 years old
• 2 years = 24 years old
• 4 years = 35 years old
• 6 years = 42 years old
• 8 years = 50 years old
• 10 years = 60 years old
• 12 years = 70 years old
• 14 years = 80 years old
• 16 years = 84 years old

Its important to note that not all cat years are created equal, and cats can live to be anywhere from 20 to 25 years old.
