The cat-years converter

Cat time runs fast at first, then settles to about four human years per birthday. Here is where Her Fluffiness stands, plus a converter for any cat you know.

~14

human years old

~9.9 months old in cat time, which makes Picha a teenager (this explains a great deal).

The nine-lives itinerary

  1. Kitten

    0 to 6 months

    Chaos in its purest form. Everything is prey, including feet.

  2. Junior

    6 months to 2 years she is here

    Full size, teenage judgement. Every house rule gets tested twice.

  3. Prime

    2 to 6 years

    Peak cat: maximum glamour, minimum tolerance.

  4. Mature

    6 to 10 years

    The executive years. Naps are meetings; meetings are naps.

  5. Senior

    10 to 14 years

    Gracefully unbothered. The staff remain on duty.

  6. Super senior

    14 years and up

    Legendary status. Every sunbeam in the house is reserved.

The official route for life number one. The other eight are expected to reuse the itinerary.

That cat is a teenager (this explains a great deal).

The common veterinary rule of thumb: year one counts as 15, year two brings it to 24, and every year after adds about four. Kitten months are interpolated from the standard chart. For bragging rights, not for medical decisions.
