Cat year chart (5 interesting facts)

In this article of “Cat year chart,” we will calculate the age of a cat in human years along with this we will discuss the life stages of a cat and how we can determine the age of the cat or a kitten.

Cat year chart

The cat year chart tells you how old your cat is in human years. The old seven-year rule is not very accurate because the kitten grows rapidly during the first or second year of its age. The method of developing a cat year chart is accurate and it gives us an estimation of the cat’s age. 

The cat’s first year is equal to 15 years of human age and the cat’s 2 years is equal to 24 years of human age.

How to calculate cat age in human years?

There is a difference between the age of cats and humans. A cat year chart helps us to see the change in the cat’s body during different stages of his life. There are certain factors like weight, breed that affect the age of the cat.

If your cat is adopted or you adopt a stray cat you need to look for other things like the teeth but they are prone to changes due to health issues. The best way to determine the age of the cat is to visit a veterinarian. The above chart should be displayed on the wall in the form of a poster.

An owner must formulate a cat year chart for the correct estimation of his cat’s age.

Following are some factors you can use to calculate the age of your cat:

1-A cat muscles

The younger cats have muscular skeletons therefore they are more active than older cats. The older cats have bony prominences that give them a skeleton-like appearance. This factor varies among breeds and the exact age should be estimated from the cat year chart.

2-A cat eyes

Younger cats have bright, clear, and discharge-free eyes depending upon the breed of the cat. Older cats have their eyes rough and jagged. The older cats have cloudy eyes but there is a certain disease condition in which the eyes appear cloudy.

If you have a cat who has cloudy eyes you need to consult a vet to figure out why it happens. This character varies among breeds and the correct estimation of age should be from the cat year chart. It is easy to estimate from the chart.

3-A Cat teeth

An Older cat has stained teeth. A Younger cat of age less than 1 year has white teeth. The first teeth appear in a two to four weeks old kitten. Slight yellowness indicates that the cat’s age is in between 1 to 2 years. A Cat having tartar on his teeth has an age between 3 to 5 years.

Tartar on cat teeth

It should be noted that certain cats have more tartar on their teeth due to their food. Cats may not have tartar in their older ages due to proper dental care. A cat having missing teeth is an old cat between the age of 10 to 15 years, but there are certain conditions in which teeth are removed like dental surgery.

4-A Cat coat

Older cats have more thick and rough coats. Depending upon the breed certain breeds are having thick coats naturally. Older cats have grey or white patches on their coat.

Above are the factors that influence the statistics of a cat year chart, the owner should keep this in mind.

Average lifespan of a cat

The average lifespan of an indoor cat is 16 to 18 years or even 20 years which is equal to 96 years of human age in the cat year chart. The life expectancy of the cats depends upon certain factors like health status, diet, and physical activity.

The average lifespan of an indoor cat is more than a wild cat because in the wild there is a competition for food and there is always a threat of predators. Wild cats are prone to diseases more than an indoor cats.

There is also a breed difference in the lifespan of the cat. For instance, Manx and Siamese breeds can live longer than any other breed of cat.

The longest lifespan was 34 years which is equal to 153 years in cat age. This gives the idea that cat life expectancy has been increased during the past decade. Cats live more as compared to humans if we compare the size of both species.

Life stages for a cat

There are six stages for a cat:

  1. kitten-which is in between 0 to 6 months of age. In this stage, the cat is growing rapidly but is not sexually mature. The kitten learns from every animal or person around him and they groom his personality. Behavior and physical development are very rapid at this age. After 2 to 3 months the kitten leaves his mother and becomes more independent and starts to explore new things.
  2. Junior-is in between 7 months to 2 years. In this stage, the cat has attained full size and he starts learning about life and how to survive in life. Junior does not require as much care as a kitten. They also do not require as much vaccination as a kitten.
  3. Prime-which is in between 3 to 6 years. The cat is behaviorally and physically mature and is active. He can enjoy life and has the energy to play and do a lot of stuff. This is the energetic period but if there are some congenital abnormalities then the cat will suffer, so it is recommended to have a health check-up at a clinic. This is the base year of learning new things.
  4. Mature-which is in between 7 to 10 years. The cat is equal to the mid ages human like that of 40 or 50 years of age. At this age, you need to look for the proper nutrients intake and the diseases like kidney problems and joint problems in these cats.
  5. Senior-which is in between 11 to 14 years. The cat is equal to 70 years of human age. In senior cats, joint diseases are hidden. Proper care and regular health check-ups are necessary to keep the cat fit and healthy. There should be a change in the diet of the senior cat.
  6. Super senior-which is 15 years and over 15 years old. Many cats reach this age but they do not look like super seniors. These cats are also called geriatric cats. They are from 15 to 20 years. These cats should be visiting a vet every six months. These cats develop hearing and other abnormalities or decreased hearing ability. These cats are often on medications or special diets to support their life activities.

These stages help us to determine how old the cat is from the start and what he needs in his diet to get the best out of his life. We also know that like humans cats are also prone to diseases like arthritis in their older ages, so we can really care about them by knowing the stage of the cat.

The “International Cat Care” launched a program known as “Cat Care for Life”. This program provides health check-ups and recommendations according to the age of the cat.

The cat year chart is necessary to determine the possible diseases of cats at a particular age.

How to determine the age of your kitten?

Newborn kittens have their eyes closed and they are enabled to eat, drink, and cannot keep themselves warm. They rely on their moms for everything. One day kittens can stand and require bottle feeding after every two hours. Their eyes are closed and their ears are folded.

One week old cat

At the end of the first week of the kitten, they started to make sounds. They are still unable to do anything on their own. They rely on their mother to feed them and to protect them. 

One-week-old kittens are around eight-ounce in weight and are slowly becoming aware of their surroundings. Their eyesight is still not focused.

In the second week of their age, their eyes open and ears are uncurled, but they still require a caregiver or mother to feed them and protect them from harsh environments and predators.
