Printable Cat Age ChartCats Age Chart
Last updated
This is a print-friendly version of our cat years to human years chart, built to fit on a single sheet of paper. It covers cat ages 1 through 25 using the same AAHA veterinary formula as our cat age calculator: the first year counts as 15 human years, the second adds 9, and every year after that adds 4. Unlike dogs, cats need no size adjustment, so one column covers every breed from Sphynx to Maine Coon. Every figure is documented on our methodology page.

| 1 | 15 | Junior |

catsagecalculator.comHow to use this chart
Find your cat’s age in the left column and read across. That’s it. The life stages follow the framework our calculator uses: Junior through age 2, Adult from 3 to 6, Mature from 7 to 10, Senior from 11 to 14, and Geriatric from 15 on. If your cat’s age falls between years, the calculator on our homepage handles months precisely, and our senior checker adds a 12-sign checklist for cats approaching their senior years.

The chart fits on one portrait page in every major browser, in full color on color printers and clean grayscale otherwise. Hit the print button above (or press Ctrl+P / Cmd+P), and the page automatically strips the navigation, buttons, and everything else you don’t need on paper.
