It’s notable that only after one year of life, a cat reaches the equivalent of human adolescence, and at 15 cat years, it’s already in old age. From 2 years to 10 years, one year in a cat’s life equals 4 human years. This calculation continues in increments of 4 after the age of 12. Thus, you can determine your cat’s age in human years.
According to Guinness, the world’s oldest cat lived for 38 years and 3 days. Creme Puff the cat was born on August 3, 1967, and passed away on August 6, 2005, in Texas, USA.
