The first year of your cat's life is considered the equivalent of 15 human years. The second year adds nine more human years to the total, which means 2 cat years are approximately 24 human years. After this, each additional human year is around four 'cat years'.
While their growth may slow down after 6 months, the development and growth phase will usually continue until the cat is roughly one year old, which is why many veterinarians treat the 12-month point as the age when a kitten becomes an adult.
Indoor cats generally live from 12-18 years of age. Many may live to be in their early 20s. The oldest reported cat, Creme Puff lived to be an amazing 38 years old. Outdoor cats generally live shorter lives due to being more likely to be involved in traumas such as motor vehicle accidents or dog attacks.
Although a cat is considered an adult by one year of age, developmentally speaking, kitten adolescence typically lasts until a cat reaches eighteen months or so.
The best way to determine a cat's age is to consult a trusted veterinarian who can determine an approximate age of the cat by examining its teeth, eyes, fur, and overall maturity. Still, be aware that your vet cannot pinpoint an exact age, just provide an educated guess as to how old your cat is.
Cats are considered "full-grown" when they reach 18 months, which is equivalent to the age of a 21-year-old human, according to PetMD. Between the span of those 12 to 18 months, a cat can continue to grow in size. Some breeds do not even reach full size until they are 2 years old, says PetMD.
The transition to adulthood ordinarily occurs from 1 to 2 years old. At this time, and possibly after neutering, a cat may retain a lot of energy but should be notably calmer with it reaching full maturity at 2. From 3 to 10 years old, a cat is relatively calm but remains active.
The answer is clear when you realize that the average lifespan of an indoor cat ranges from 10 to 20 years, whereas cats who go outdoors typically live only 2 to 5 years.
If this sounds familiar, they might be going through the 'Terrible Two's' phase! Cats are juniors until the age of 2, and like human children, may start to show a different temperament between 6 months and 2 years old, even progressing from the (sometimes) defiant 'Terrible Two's' to becoming a stroppy teenager!
The first year of a medium-sized dog's life equates to about 15 human years. Year two for a dog equals about nine additional human years, making the dog about 24 in 'dog years'. After age two, each human year adds around five dog years.
For example, if your cat is 7 years old, it is 45 years old in cat years.
In most cases, cats will purr when they are in a relaxed environment, sending out waves of calmness. This may also occur when you stroke them, and if this is the case, your feline friend is feeling happy or sociable. However, cats purr to communicate other emotions and needs, too.
Let's talk about Cat Teeth:
Teeth may start to dull around the 2 year mark. Between the ages of 3 and 5 years, the teeth may start building up a little tartar around the gum line (especially the molars) and tooth wear may be visible.
By one year old, your kitten will be an adult cat. She may still act like a mischievous kitten, but her needs will have changed. Now that she's fully grown, she'll require an adult cat food that will provide her with the appropriate levels of nutrients, vitamins and minerals she needs through adulthood.
Of course while some cats get more affectionate as they age, this is not true for all cats and can depend on a number of different factors such as personality, environment, breed and more. Age also comes with physical effects that often cause cats to decrease activity and become less playful.
When Do Kittens Become Adults? Most kittens are considered adults around their first birthday. For some larger breed cats, like Maine Coons, it can take up to 18 months to 2 years to reach their full size. Between eight months and two years of age, kittens reach their full size.
Mature. As your cat grows older, you will start to see behavioral changes. From 7-10 years of age, your cat begins to lose their drive to play and is less active. This is a normal shift in activity as your cat is comfortable in their environment and routine.
At 26 years old, Teddy is Australia's oldest living cat, and his owner, Fran English, is applying to the Guinness Book of World Records to make it official. English adopted Teddy in 2014 when his elderly owner could no longer care for him, and was shocked when Teddy's microchip revealed that he was born in 1991.
Cats tend to favor one person over others even if they were well-socialized as kittens. Cats are expert communicators and gravitate towards people that they communicate well with. Look for communication cues from your cat, such as your cat approaching you in search of food or petting.
As in humans, female cats tend to live for longer than male cats. Neutered cats are also likely to live for longer than intact ones, and pure breed cats are less likely to live as long as crossbreeds.
