The formula is as follows: if you want to know the age of a dog in human years, you must multiply its natural logarithm by 16 and add 31. When a cat has fully grown into an adult, each cat year is equivalent to 4 human years. The aim of the study, in addition to finding the formula for calculating a dog’s age in human years, was to establish an equivalence between the life stages of both species. The first year of a cats life is equivalent to 15 human years whilst the second year is only equivalent to 10 human years.

Converting dog years to human years depends on various. When your dog is one year old, they will be about the equivalent of age 14 to 15 in human years. Dog years are multiplied by seven to get a human age, as a dog lifespan is a seventh of a persons. Instead, you’ll find it’s quite variable. By that formula, a kitten is 3.5 years, which shoots holes into that 7-year theory. It’s generally agreed, however, that dogs age much faster in the first two years of life than any other time. A cat becomes sexually mature around 6 months, depending on the breed.
