You recently acquired a new Siamese cat, a stunning blue-eyed ball of white fur, and you might be wondering what to expect as it develops into a full-grown, mature “cathood.”

These cats are a truly elegant cat breed. Their bodies with gorgeous spots and their muscular and slender bodies indeed make wonderful cats. On top of that you add bright blue eyes… and voila, perfection!

The Siamese cat, which originated in Thailand, was not well-known in the United States until the early 1900s. Only a few individuals found the Siamese cat’s unusual appearance to be appealing.

But by the turn of the century, it had become commonplace in many American homes. However, don’t anticipate the Siamese cat to behave in such a manner just because it appears aloof and sophisticated.

You might be surprised by how loving, attentive, and personable your new Siamese kitten is when you first bring it home. Let’s see the Siamese cat growth chart in order for you to learn what to expect at a certain age.

How Big Do Siamese Cats Get?

Kitten (0 To Six months)

Newborn Kitten

I think there is nothing cuter than a little kitten in its infant stage. The Siamese cat is similar in that it has a lot of adorable prominent newborn features, like folded ears and immature vision. With their possibilities, they will only look for the mother cat and her belly.

White Kitten

Your Siamese cat won’t exhibit the distinctive “point” coloring when it is young. Siamese kittens are entirely white when they are born, but by the end of the first week, you will begin to notice the very first traces of their adult coloration.

However, those enormous bright blue eyes will remain throughout adulthood, unlike the majority of other cat breeds. The points on their paws, tail, nose, and ears will slowly darken at three weeks of age, but we will not know the color of their points until they reach one year old.

Smart Kitten

Your little Siamese will have an active, demanding personality that will take up a lot of your time. This kitten is not the one for you if you want a calm lap cat. In comparison to other cats, Siamese are smarter and have more intricate vocalizations.

You should exercise caution because your kitten will take advantage of this by speaking to you frequently to get your attention. However, due to his intelligence, your kitten is perfect for training, so it shouldn’t be a problem to teach him new tricks or take him on a leash adventure.

Growing Kitten

The first few weeks will see rapid growth in them. By the second week, you should notice that your cat has gained weight and grown in size—typically by about twice what it was at birth. Additionally, you will notice their sniffer starting to function at this point.

Even though it sounds adorable, these kittens should be crawling around. When they reach the third week of their lives, you should notice that they are beginning to walk, though they will move a little jittery.

Their kitten teeth will also start to erupt around this time, and their ears should start to erupt. He’ll start displaying some of his adult characteristics. The light baby blue eyes of your kitten will gradually turn into the deep sapphire blue Siamese are known for.

You’ll notice that your feline friend’s personality will start to emerge once they reach the fifth week. This is an exciting time because you can observe how they behave and play as well as the attitudes they are forming.

You’ll notice the cat beginning to stop drinking milk and start concentrating more on food if it still has its mother cat. The owner should do this again if the mother is not present.

The color points will be much more apparent and almost fully developed once they reach the eight-week mark. Additionally important at this time, human contact should begin as early as five weeks and last up to 13 weeks.

A newborn kitten needs socialization at this stage, so you must approach it with playfulness and love. The veterinarian is essential right now for shots as well. By the age of five months, another significant vet visit should take place.

Siamese kittens will have large litters and can go into heat as early as five months. Therefore, talk to your veterinarian soon about having him spayed or neutered if you don’t want additional little kittens to care for.

As these cats reach sexual maturity at 6 months of age, maybe you should consider spaying or neutering them if you aren’t a breeder.

Junior (6 months To 2 years)

You’ll notice that these kittens start to get much more active and mobile around the age of six months at this point.

They are in an odd stage of development right now because they aren’t quite adults but are emerging from the kitten stage. It won’t be until your Siamese kitten is two years old that they are considered to be an adult.

At this point, their coloring will continue to darken, and the temperature of their body will influence how dark they turn out to be. He will become more inactive and gain weight, which will raise his body temperature.

Siamese Cat Eating Habits

Siamese cats are renowned for being picky eaters. They will nag their human parents for food and be picky about the food they’ll eat. Gladly we can offer you the 9 Best Tasting Cat Foods for Picky Eaters. Don’t let them starve themselves, since they tend to protest when they don’t like the food.

But it’s crucial to give your Siamese cat its own special food, particularly cat food that is created especially to meet their dietary requirements.

Your Siamese will quickly display weight gain. They can easily develop a pot belly from overeating due to their long, lean body, but their slim legs were not designed to support additional fat.

Siamese Cat Temperament

Siamese cats are renowned for being affectionate, sociable, and friendly. Expect your Siamese to have a strong bond with you as their human parent and to be loving and trustworthy.

However, they won’t enjoy being left alone and might become attached to just one resident of the home. (You might discover that your feline friend has developed intense jealousy toward specific people or any other pets you may own.

This is just a part of who they are, so don’t be alarmed. Siamese cats are typically sensitive creatures, and if they are ignored or upset about something, their feelings may be hurt.

Additionally, you should be ready for their energetic and somewhat unpredictable behavior. Due to their tendency to be territorial and protective, they may also have trouble interacting with strangers.

As they are highly intelligent creatures, they’ll need a lot of stimulation. They get along with kids, other cats, and even dogs who are tolerant of cats, though they bond more deeply with a single person.

However, they can be prone to mischievous exploits if they don’t get enough stimulation. Keep in mind that it is not the greatest idea to leave Siamese cats alone for a long time since they can develop depression and anxiety.

Some Siamese cats have incredibly loud, low-pitched vocalizations known as “Meezer,” which have been compared to baby cries. Additionally, these Siamese cats will always want your attention, no matter what, that’s why some consider them to be needy.


Siamese kittens enjoy jumping. The long, slender body of your Siamese will relish making graceful, high jumps from great heights. Height will fascinate him, and he won’t be afraid to climb up on every piece of furniture.

In order to keep your cat amused and active, make sure you have lots of perches, high surfaces, and cat trees. The Siamese breed is a highly intelligent, quick, and active one that enjoys playing as well as jumping.

Adult (2 To 10 years)

Your Siamese cat will become more laid-back and mellow as it gets older. They will still require people to pay them attention and toys to keep them occupied, though. Siamese cats that are adults are patient and tolerant, and they get along well with new people and pets.

In addition to being quite attached to their owners, adult Siamese also have a tendency to follow their human parents around the house.

Siamese are not typically lap cats, but older Siamese will want to cuddle with their owners. They might also be overly needy in their constant quest for attention.

Siamese Cat Health Issues

A Siamese cat will have a higher chance to get sick as they are older. One of the main issues with Siamese cats is their poor night vision.

Siamese cats have trouble picking out details in the dark. This issue is brought on by the pigment in their stunning blue eyes.

They lack a layer on their eyes known as the tapetum lucidum that aids other cats in night vision. Siamese cats frequently experience other health issues besides poor vision. The adult Siamese cat faces additional health risks, such as:

• Glaucoma

• Breathing difficulties

• Feline OCD

• Calcium oxalate bladder stones

Feline Hyperesthesia Syndrome

• Crossed eyes

• Chronic renal failure


• Vestibular disease

Senior (10 To 15 years)

Your Siamese cat will reach senior citizen age when it turns 10 years old. No need to worry; many cats today live well into their early 20s.

It’s perfectly normal for your Siamese cat, who is 10 years old, to not be as agile or able to leap as high onto the kitchen counter. Your Siamese cat could not jump as high as usual, has more napping time, is less playful, slow pace, and so on.

Your cat might become anxious in unfamiliar surroundings if they are meeting new people or are in a strange place. Early on, this might not have been the case, but as cats age, they become less receptive to change.

Siamese cats are a very distinctive breed. Their vocalization increases as they get older. Even as they age, they develop a greater sensitivity to loud noises, strange sounds, and strangers. Unfortunately, they will be more likely to develop a variety of illnesses, including diabetes and kidney disease.

Geriatric (Over 15 Years)

When a Siamese cat reaches the age of 15, just like us, they start to become much slower and less active than when they were younger.

As they age, it’s important to keep in mind that they could experience vision and hearing loss, as well as lessen their ability to perform well in outdoor environments.

Senior Years

Additionally, as they age, you’ll notice that they begin to sleep more, become less active, and possibly even become moody.

All of this is typical for an aging cat, just as it is for us as we age. It’s important to keep in mind that as they age, they will also become less sensitive to things like startling or loud noises. An older pup’s tendency to distance itself from others is another characteristic.

Don’t be alarmed if it appears that they are drifting away from you; it is perfectly normal for them to grow accustomed to spending more time alone as they age.

But you can help improve their spaces where they rest and relax and make them as comfortable as you can, rather than letting them grow distant.

You’ll also need to work hard to continue spending a lot of time with them, just like you did when they were infants. It is crucial to maintain this because Siamese cats require attention throughout their entire lives.

Living Beyond 16

For a Siamese cat, living past the age of 16 is truly a blessing. They are now well into the latter part of their life’s twilight.

Everything that was mentioned earlier in the senior years still applies here, albeit with a few more sophisticated elements, like movement and energy levels. They may be older and have a variety of health issues that are related to aging.

Additionally, they are likely less attentive and responsive than they once were, and she occasionally may come off as very confused.

Your Siamese cat probably sleeps more frequently even if it is still in good health. It is expected that they are less playful and do not interact as much with humans. They can easily forget to use the litter box and they won’t groom as much as they used to.

Make sure to keep an eye on their behavior, if you see something really unusual in their behavior, maybe you need to see the vet. Your feline friend needs you to feel comfortable, secure, and stress-free so make sure to offer him all of that.

Their daily routine should remain the same, and it’s critical to ensure that they maintain a healthy lifestyle for as long as they can. Even at this point in their lives, consistency is essential to ensuring that they maintain their levels of happiness.

Siamese Cat Appearance

Siamese cats come in two different varieties, traditional Siamese and modern Siamese cats. Every type is distinct in some way. Specific characteristics define both the Siamese cats of today and the breed standard. These qualities consist of:

Muscular, slender and elongated body

• Gorgeous blue, almond-shaped eyes

• Long neck

• Short, fine and glossy hair

• Slender tail

• Large and wide-based ears

• Triangular head shape

The pointed color pattern is the Siamese cat’s most distinctive characteristic. Due to a mutation in the enzyme that produces melanin, a pointed color pattern is a type of partial albinism.

The coolest areas of the cat’s body develop dark coloration (points) as a result of this heat-sensitive enzyme becoming active.

The majority of Siamese were born with “seal” points, which are extremely dark brown, almost black, but on rare occasions, they were also born with blue points” (cool gray), “chocolate,” or lilac” (pale warm gray) points.

Anything other than a “seal” was initially thought to have inferior coloring and was ineligible for breeding or showing.

Many of the Siamese cat’s hues eventually gained official recognition from the various breed associations. These then spread throughout the different programs and started to appear more frequently.

Following this, we observed a variety of patterns being bred, from tortoise-shell points to red and cream points, which began to gain popularity among both amateur and professional cat lovers.

The majority of the Siamese breed that originated in Thailand would have a kink in their tail, which many people considered to be a flaw and still do today. Although many breeders have now largely eradicated it, it is still present in some areas of Thailand.

Siamese Cat Personality

These cuties are so empathetic that they will sense any of your emotions and try to comfort you. Extremely sociable, they’ll make friends with those who they decide to trust. Even as adults, they still seek out social interaction and are playful.

Compared to other cats, they frequently behave more like dogs. Siamese cats can experience depression if left alone for an extended period of time because of their need to be around people. To address this issue, they are frequently purchased in pairs.

Being extremely talkative and opinionated is one of the most significant characteristics of the Siamese cat. When they talk in their raspy and loud voice, they want you to pay close attention to them. They act as though they are watching everyone’s every move while following people around.

Siamese Cat Overall Health

Sadly, compared to many other cat breeds, the Siamese breed of cat generally has a higher mortality rate.

This is quite low compared to other breeds, who typically live into their late teens or even early 20s if they lead active, healthy lives. However, a number of health problems, including tumors and digestive issues, are connected to Siamese cats.

The same albino genotype that results in their colored points also prevents Siamese cats from having the tapetum lucidum, a component of their DNA that contributes to the development and enhancement of the dim light in other cats’ eyes.

This was a recurrent mutation, and sadly, Siamese cats frequently experience these health issues.

Life Expectancy Of Siamese Cat

The average lifespan of a Siamese cat is roughly 15 to 20 years, more or less, when you take into consideration a few parameters. However, a number of health problems could develop and contribute to them dying even earlier than the average lifespan.

As was previously mentioned, a variety of issues might arise, but they might also live longer, so it could go either way. Although there is no surefire way to predict how long your cat will live, there are always things you can do to ensure its longevity and healthy lifestyle.

To have a healthy Siamese cat for a long time these parameters need to be respected:

Proper nutrition

• High-quality and balanced diet

• Regular exercise

• Fun playtime

• Unconditional LOVE

Wrapping It Up

Now that you are aware of what to anticipate, keep in mind that we are merely providing you with averages based on the statistical data we have access to. As each cat is an individual, it’s possible that DNA and other factors, such as spaying or neutering, will have an impact.

However, this Siamese cat growth chart will help you observe your kitten’s healthy weight and height. Additionally, because each cat is unique, it’s perfectly normal for them to occasionally be smaller or larger.

If you are worried about your Siamese cat’s weight, you can always go for a vet check-up to rule out any health issues and if a diet change is necessary, you’ll be able to take care of it right away.

Keep in mind if you love your cat unconditionally and take great care of her health and up-to-date vaccinations, your Siamese cats should have long lives.
