How is cat age calculated?
Cats mature very rapidly in their first two years. Year 1 is equivalent to approximately 15 human years, year 2 adds 9 more (24 total), and each year after that equals about 4 human years. Unlike dogs, there is no significant size variation in cat aging.
This formula is based on guidelines from the International Cat Care organization and is widely used by veterinarians worldwide.
