Calculator Cats

Cat age calculator

How old is your cat in human years, and which life stage is that?

32in human years

Life stage: Young adult

Care tips for this life stage

  1. Book a checkup at least once a year.
  2. Use year-round parasite prevention; indoor-only cats are at risk too.
  3. Watch for weight gain and keep play, toys and scratching posts in the routine.

How this calculator works

The calculator uses the International Cat Care conversion. The first two years of a cat's life equal 24 human years, with 15 reached at the first birthday. Each year after that adds four. Cats under 2 years are read from the same chart, which starts at 1 month. The life stage shown follows the 2021 AAHA/AAFP Feline Life Stage Guidelines. Those guidelines group cats by age and give no human-year equivalents.

Questions

Is one cat year equal to seven human years?

No. A cat reaches the equivalent of about 15 human years in its first year and about 24 by the end of its second. After that each year adds about four.

When is a cat a senior?

The 2021 AAHA/AAFP Feline Life Stage Guidelines place cats in the senior stage when they are over 10 years old.
