is cat years like dog years

For cats, one human year is roughly equal to 6 – 7 cat years. For dogs, it’s slightly more complicated, as size and weight also have an impact. Generally, the heavier and larger the dog, the more swiftly they age.

The 5 cat life stages:

Now that you know how old your cat is in human years, what does that figure actually mean? Well, cats typically live between 20 and 25 years, and during that time, they go through different life stages in a similar way to humans, but much more quickly than we do.

In 2021, the American Animal Hospital Association and the American Association of Feline Practitioners updated their guidelines on cat life stages into a five-stage grouping (simplified from the previous six stages).

Which life stage is your cat experiencing?

Kitten: From birth to 12 months of age: During this time, they grow quickly.

Young adult: 1-6 years old: During this phase, cats reach their maximum size and physical well-being. They also learn about social structure and behavior.

Mature adult: 7–10 years old: This age range is comparable to human middle age.

Senior: Over the age of ten: Cats at this age need extra attention and regular check-ups because they are more vulnerable to different health problems. This stage is also known as geriatric.

End-of-life: A cat’s final stage of life encompasses the changes it experiences as it approaches its expiration.

Generally speaking, the best chance for your cat to live a long and healthy life is to assist them in maintaining a healthy weight, diet, and schedule of frequent veterinary visits!

True cat age was found in a study published in 2017 by iMedPub Journals, while true dog age was discovered in a study published in 2020 by Cell Systems. Unfortunately, these equations aren’t as simple as the seven-year rule with the new equation for cat age being

The primary issue with these calculations arises during the first year of life, when the development of smaller animals such as dogs and cats surpasses that of humans, even after taking into consideration their reduced lifespan. According to the original seven-year rule, a one-year-old dog or cat is equivalent to a seven-year-old human. A one-year-old dog is actually equal to a 31-year-old human, while a one-year-old cat is equal to a 16-year-old human. 6-year-old human. Remarkably, the old seven-year rule is not too far off because as dogs age, their aging process slows down and approaches the original seven-year rule result. The 1950s saw the introduction of the original seven-year rule, and it was not until recently that new research led to the development of new formulas.

These kinds of studies do more than just refute the seven-year rule or provide an accurate estimate of the human age equivalent of your beloved pet. When you discuss the oldest dog or cat, these studies provide some fascinating information. The oldest cat ever lived to 34, which is 155. The oldest dog lived to be 29 years and 5 months old, or 85 years in dog years, while the oldest cat was 64 years old. The dog study reflects our recent advances in genetic technology. The dog study guides veterinarians’ treatment decisions and helps us create a new epigenetic clock for dog cells to measure their age. Additionally, these new findings represent a breakthrough in our knowledge of how various species age. These kinds of findings advance our knowledge of the fundamental causes of aging and may one day enable us to slow down the aging process in humans.

The majority of us are familiar with certain formulas that can be used to convert the age of our favorite animal to that of a human. Most of these formulas are linear conversions, and the most well-known one says that a human year is equivalent to seven years for a dog or cat. It turns out that this isn’t the case, and that people age differently from dogs and cats.

How do I calculate my cat’s age in human years?

The answer to the question, “How old is my cat in human years?” is not too complicated. The process for figuring out a cat’s age is fairly standard, unlike that of a dog, whose age is determined by size and breed.

According to the American Animal Hospital Association(AAHA), these age guidelines have been created and agreed upon by the AAHA, the Feline Advisory Bureau (now known as International Cat Care), and the American Association of Feline Practitioners (AAFP):

  • A cat’s first year of life is roughly equivalent to 15 human years.
  • A cat’s second year of life is equivalent to nine more years.
  • Every year a cat lives after the second is roughly equivalent to four human years.

Is cat years similar to dog years?

In reality, a one-year-old dog is equivalent to a 31-year-old human whereas a one-year-old cat is equivalent to a 16.6-year-old human. Surprisingly, the old seven-year rule is not too far off as the dog aging process slows down as they get older and gets closer to the original seven-year rule result.

Who ages faster cats or dogs?

It mostly just appears that dogs age faster because they exhibit more obvious signs of aging compared to cats. Plus larger breeds of dogs simply don’t live as long as cats, or even their smaller dog breed counterparts. “Lifespan and aging are all related to the animal’s genetic makeup,” says Dr.

Is the cat or dog older?

It seems the that the cat family branched off first, 10.3 million years ago, before the family of dog-like mammals, 7.8 million years ago.
