With dogs it is well known: One dog year is seven human years. But what about cats?

Convert cat years to human years

Cats age much faster than humans. This is understandable, because cats usually live 12 to 18 years, some cat breeds up to 20 years. In humans, puberty has just finished and the development into a young adult is progressing. A cat undergoes the fastest development in the first year. The first cat month after birth corresponds to six human months. At three months, the cat is already five human months old. At the age of six months the cat reaches an age of 10 years converted into human years. At the end of the first cat year, the cat is sexually mature and can reproduce. This corresponds approximately to a human age of 15 years.
