The "seven cat years per human year" rule is a myth. Cats mature very quickly: by their first birthday they are roughly like a 15-year-old human, and by two they are like a 24-year-old. After that, each cat year counts as about four human years. This calculator follows the chart used by International Cat Care and the American Association of Feline Practitioners. It interpolates between the milestones for kittens, so a 6-month-old kitten is about 10 in human terms. Life stages follow the same guidelines: kitten, junior, prime, mature, senior and super senior.
From about age 11, cats benefit from twice-yearly vet checks, blood pressure and kidney screening, and softer, warmer resting places.
Indoor cats commonly live 13 to 17 years, and many reach their 20s. Outdoor cats face more risks and often have shorter lives.
About 15 human years. At two it's about 24, and it adds about 4 human years each year after that.
No. That rule is inaccurate for cats. They age fastest in their first two years and more slowly afterward.
From about 11 years old (about 60 in human terms). Cats 15 and older are called super senior.
The record is Creme Puff, who lived to 38 years. Most cats live 12 to 18 years.
Only slightly. The chart applies to cats generally. Some breeds tend to live shorter or longer, but they follow the same pattern of maturing early.
