Very often, the basic ratio of feline and human age is considered to be 1 to 7, i.e. A 1-month-old kitten should correspond to a 7-month-old child, a one-year-old to a seven-year-old, etc. But this method of recalculating the age is not entirely accurate, because. in the first months and years of life, a kitten develops much faster than a child. By the first birthday, a fluffy pet can be considered a teenager, by the second – a full-fledged representative of youth. Further maturation of the cat becomes smoother: 1 cat year can be equated to 4 human years, and after 15 years – to three.
Below is a table of the age of a cat by human standards: from 1 month to 20 years.
