Russian Blue age in human years
Cats keep their own clock. The first year counts for 15 human years and the second adds 9, so a two-year-old russian blue is already 24. Every year after that adds 4, the slowest rate of any pet on this site. A five-year-old russian blue is around 36, and cats are generally considered seniors from about 11. Most live somewhere in the 12 to 18 range, and a 15-year-old at 76 is impressive but not unusual.
