In this alternative formula, Hotchner delves more specifically into the corresponding ages of young kittens to similarly young human children. Tracie Hotchner, author of The Cat Bible, offers a slightly different variation on the aforementioned calculation. However, some breeds take years to fully mature. How do you know when your cat has stopped growing? Most veterinarians agree that your cat is done growing between 9 months and 2 years old. In fact, healthy kittens grow 8 times their size in just about 8 weeks ! By approximately 1 year old, cats will weigh at or around their adult weight, which typically ranges from 7 to 15 pounds depending on the breed. If you’re having trouble grasping early maturation in cats, look at this way: Kittens do most of their growing in the first 6 months of life.

That would make a 5-year-old cat about 36 human years old. Then, for each year after the first two, equate each cat year to about four human years. That’s why a one-year-old kitten is the developmentally equivalent age of a 15-year-old human, and the physical maturity of a two-year-old cat is roughly equivalent to a 25-year-old human. And the little bit of work they do require can be done with a self-cleaning litter box. Domesticated house cats have a gestation period of only 66 days and give birth to kittens that require just a small portion of the kind of attention and care that human babies require. They are still much closer to their wild roots than us bipedal humans.Ī primary example of this is the way that humans have evolved to have long gestation periods and then even longer periods of intensive rearing and childcare. Your feline companion is your precious baby, we know, but you must remember that cats are still animals. Your cat's age in human years Early maturation
