Detailed Siamese Cat Growth Timeline

So, you’ve got yourself a new Siamese cat – a gorgeous cat with blue eyes and white fur – but you might be curious about what to anticipate as your little Siamese kitten develops into a fully grown adult cat.

The Siamese cat is a really fancy-looking breed of cat, with its slim and athletic body shape and its pretty white body with dark markings – and let’s not forget about its captivating bright blue eyes.

The Siamese cat, which originally came from Thailand (formerly known as Siam), didn’t gain popularity in the United States until the early 1900s. The unique look of the Siamese cat wasn’t appreciated by many people.

  • With its Triangular face
  • The Siamese cat has color points on its feet, tail, ears, and face.

However, by the year 2000, it had become a common feature in many American households.

However, don’t assume that the Siamese cat will behave in a sophisticated and distant manner just because it looks that way. When you bring home a new Siamese kitten, you may be pleasantly surprised by its affectionate nature, attentiveness, and vibrant personality. Here is a timeline that outlines what you can anticipate at each stage of your Siamese cat’s life. You can find more information about the average lifespan of a Siamese cat here.

Phase 1: Kitten (0 – 6 months)

Newborn Kitten

The early stage of a lovely little kitten is always delightful. The Siamese cat is no exception, displaying several adorable characteristics as a newborn, including folded ears and limited vision. Despite their limited mobility, they manage to navigate their surroundings by wiggling until they locate their mother’s tummy to nurse.

White Kitten

As your Siamese cat is still a baby, it won’t have its distinctive “point” coloring yet. Siamese kittens are born all white, but by the end of their first week, you’ll begin to notice faint signs of their adult coloration. However, unlike many other cat breeds, their big, vibrant blue eyes will remain throughout their adult life.

When a Siamese cat is about three weeks old, its ears, nose, tail, and paws will begin to darken in color. However, it will take approximately one year for the full colorization to become visible.

Smart Kitten

In terms of personality, your Siamese cat will be energetic and needy, needing a significant amount of your attention. If you prefer a relaxed and easygoing cat, then this kitten may not be the right choice for you. Siamese cats are highly intelligent and have more intricate vocalizations compared to other cats.

Watch out, because your Siamese cat will use this to their advantage, communicating with you often to grab your attention. However, their cleverness makes them perfect for training, so teaching them new skills or taking them on a leash adventure should be a breeze.

Growing Kitten

During the initial weeks, the growth of Siamese cats is quite remarkable. By the second week, you will notice a significant increase in their weight, usually around double their size as newborns.

Additionally, this is when you’ll notice their sense of smell starting to develop. These little kittens will also start crawling, which is incredibly cute. By the third week of their lives, you’ll see them taking their first steps, although they might be a little unsteady.

At this time, their kitten teeth will start to appear, and their ears will also begin to rise. They will start to exhibit some of their adult characteristics. The light blue eyes of your kitten will gradually change to the deep sapphire blue that Siamese cats are known for. By the fifth week, you will notice their personality starting to emerge.

This is a thrilling period because you can observe their behavior, playfulness, and the type of personality they are developing. If the kitten is with its mother, you will notice it gradually weaning off milk and becoming more interested in food. If the mother is not present, the owner should replicate this process.

By the time Siamese cats reach eight weeks old, their color points become more prominent and are almost fully developed. It is important to start introducing human contact as early as five weeks and continue until they are 13 weeks old. Socialization is crucial during this period, so it is essential to interact with the kitten in a playful and affectionate manner.

It’s important to take your Siamese cat to the vet for shots during this time. Another crucial vet visit should occur when the cat is five months old. Siamese kittens can start going into heat as early as five months and may have many kittens. So, if you don’t want to deal with extra little kittens, talk to your vet soon about getting your cat spayed or neutered.

Phase 2: Junior (6 months – 2 years)

When Siamese cats reach around 6 months old, you’ll notice that they become more energetic and agile. This is a strange time for them because they are not fully grown yet, but they are outgrowing their kitten stage.

Your Siamese cat won’t be considered an adult until they turn two years old. During this time, their fur will continue to darken, and their body temperature will also affect the intensity of their color. Reduced activity and weight gain can contribute to an increase in body temperature.

Siamese Cat Eating Habits

Siamese cats are well-known for being choosy when it comes to their meals. Similar to dogs, they will plead for food from their human caretakers and have specific preferences. They can be so selective that they may go as far as refusing to eat until they receive the desired food.

It’s important to give your Siamese cat its own special food, especially cat food made specifically for their nutritional needs. Your Siamese cat will gain weight quickly. Because of their long and lean body, they can easily develop a round belly from eating too much, but their slim legs aren’t built to carry extra fat.

Siamese Cat Temperament

The Siamese cat breed is well-known for its friendly, sociable, and affectionate nature. You can expect your Siamese cat to be loving and trusting, and to form a strong bond with you as their human parent. However, they don’t enjoy being alone and may become attached to only one person in the household. (You might notice that your cat gets jealous of certain individuals or other pets you have. But don’t worry, this is just a part of their personality.)

Siamese cats are typically sensitive creatures and may feel hurt if they are ignored or upset. Additionally, their behavior can be unpredictable and energetic. They may also struggle with unfamiliar people because of their protective and territorial nature.

Siamese cats are playful and smart, requiring plenty of engagement to keep them amused. While they form stronger connections with one individual, they also get along well with kids, other cats, and even dogs that are friendly towards cats. However, if they don’t receive adequate mental and physical stimulation, they may exhibit mischievous or destructive behavior. Additionally, if left alone for extended periods, Siamese cats may experience anxiety and depression.

Some Siamese cats are really talkative, making a loud noise called “Meezer” that sounds like a crying baby. These Siamese cats are also very clingy and always want attention.


Siamese kittens are fond of leaping. Your Siamese cat’s slim and elongated physique will take pleasure in executing graceful and elevated jumps. They will be captivated by heights and will not hesitate to climb on any furniture. Therefore, it is important to provide ample perches, elevated surfaces, and cat trees to keep your cat engaged and physically active.

The Siamese cat, known for its intelligence, agility, and athleticism, enjoys playing and jumping around.

Awesome ways to keep their minds engaged and productive include:

  • Puzzle toys
  • Engage in physical activities by playing with teaser toys to stimulate your cat’s interest and encourage them to chase after them.

Phase 3: Adult (2 – 10 years)

As your Siamese cat grows up, they will become more laid-back and chill. However, they will still require toys to keep them entertained and people to give them affection. Adult Siamese cats are peaceful and patient, and they will easily get along with new people and animals they encounter.

When Siamese cats become adults, they are very attached to their owners and will often follow them around the house. Although they are not typically known for sitting on laps, older Siamese cats will still enjoy cuddling with their owners. They may also constantly seek attention, sometimes even to the extent of being needy.

Siamese Cat Health Concerns

As your Siamese cat grows older, he may experience an increased risk of health problems. One particular issue to be aware of is their reduced ability to see clearly in the dark. This is due to the pigment in their striking blue eyes, which lacks a layer called the tapetum lucidum that aids other cats in seeing in low light conditions.

Siamese cats face various health risks as they grow older, not just limited to poor eyesight. Some of these health concerns include:

  • Breathing difficulties
  • Glaucoma
  • Bladder stones made of calcium oxalate
  • Chronic renal failure
  • Crossed eyes
  • Feline OCD
  • Vestibular disease
  • Cat Hyperesthesia Syndrome

Phase 4: Senior (10 – 15 years)

When your Siamese cat turns 10, it enters the stage of being a senior citizen. But don’t worry, many cats nowadays are living happily until their early 20s.

It’s totally normal if your Siamese cat, at the age of 10, isn’t as quick or able to jump as high onto the kitchen counter.

Your Siamese may:

  • Slow down
  • Take more naps
  • Not jump as high
  • Not frequently engage in play on elevated surfaces
  • Not be as playful

As cats grow older, they may become more stressed when encountering new people or being in unfamiliar places, which might not have been a problem when they were younger.

Siamese cats are a really special kind of cat. As they get older, they start meowing more. When they’re older, they also get more cautious and afraid of loud noises and people they don’t know. Sadly, they’re more likely to have health problems like diabetes and kidney disease.

Phase 5: Geriatric (over 15 years)

When a Siamese cat reaches the age of 15, they start to slow down and have less energy, similar to humans. They may also experience vision and hearing loss, and may not handle outdoor conditions as well as they used to. It’s important to consider these changes as they age.

Senior Years

As cats age, they tend to sleep more and become less active, which can also make them moody. This is a normal part of the aging process for cats, just like it is for humans. Additionally, older cats may become less sensitive to things like sudden noises, so it’s important to be mindful of this when interacting with them.

Another thing about an older puppy is that they will start to keep their distance. If it seems like they are becoming less attached to you, don’t worry, because it’s completely normal for them to get used to being alone more as they get older.

Instead of letting them become distant, you can improve the places where Siamese cats rest and relax to make them as comfortable as you can. Additionally, you should make sure to continue spending enough time with them, just like you did when they were kittens. Siamese cats require attention throughout their lives, so it’s important to remember this.

Living Beyond 16

Getting past the age of 16 is really amazing for a Siamese cat. By this time, they have reached the later stages of their life, and even more.

All the things mentioned earlier in the senior years still apply here, but they are a bit more advanced in certain aspects, like movement and energy levels. They may think a bit slower now and might face various health issues related to their age. They are also not as alert or responsive as they used to be, and sometimes they may appear quite confused.

Even if your Siamese cat is still healthy, it’s likely that they are sleeping more and being less interactive with family members. This is a normal part of their growth timeline. They may not be as well-groomed as they used to be, and even the most well-behaved older cat may sometimes forget to use the litter box.

Be vigilant for any noticeable or abrupt shifts in behavior or health, but avoid being overly intrusive, as your Siamese cat may prefer attention on their own terms. During this stage and beyond, make sure to prioritize the comfort, safety, and most importantly, the stress-free environment of your Siamese cat.

It’s important to keep their daily routine unchanged and ensure they maintain a healthy lifestyle for as long as possible. Consistency is key to keeping them happy, even as they get older.

Siamese Cat Lifespan

The lifespan of a Siamese cat can vary depending on different factors, but on average, they live for about 15-20 years. However, there are certain health issues that may arise and potentially shorten their lifespan. On the other hand, they could also live longer than the average. So, it’s uncertain and can go either way.

It’s difficult to predict exactly how long your Siamese cat will live, but there are things you can do to help them live a long and healthy life. Some of these factors include:

  • Balanced Diet
  • Exercise
  • Play Time
  • Proper nutrition
  • Love

Now that you know the entire timeline of Siamese cats, let’s explore some interesting facts about their history and how they are perceived in today’s world.

Siamese Cat History

The Siamese cat is one of the earliest known types of Asian cats. It comes from a group of cats called the Wichianmat landrace, which are originally from Thailand (formerly known as Siam). During the 19th century, the Siamese cat became very popular in Europe and North America.

Siamese cats with a white or light-colored coat and dark paws have existed for many years, even centuries. They are originally from Thailand. However, it wasn’t until the 19th century that they gained popularity as pets in the western world.

Although not everyone initially embraced their distinctive appearance, Siamese cats eventually gained worldwide popularity. Even President Rutherford B. Hayes and his wife, Lucy, received a Siamese cat named “Siam” in 1878. The cat was sent to them by David B. Sickels, the American Consul in Bangkok. The Siamese breed is classified as a “natural” breed, meaning it originated from a genetic mutation.

As a result, additional cat breeds have been developed from Siamese cats, including:

  • Tonkinese
  • Havana Brown
  • Oriental

All cat organizations acknowledge the Siamese cat. The International Cat Association also acknowledges this beautiful cat and highlights its Thai origins. These cats are very popular in their home country of Thailand, as you might have guessed.

Siamese Cat Features

Siamese cats come in two distinct types: traditional and modern. Each type has its own unique characteristics.

Siamese cats are known for their distinct characteristics, as defined by the breed standard and through careful breeding.

These features include:

  • Blue, almond-shaped eyes
  • The Siamese cat has a head shape that is triangular, creating a perfect shape from the tip of its nose to each ear tip.
  • The Siamese cat has a long, slim, and strong body.
  • The Siamese cat has big ears that are set wide apart on the sides of its head.
  • Long neck
  • Slender tail
  • Short, glossy, fine fur

The Siamese cat has a unique appearance with its pointed color scheme. This color pattern is caused by a mutation in an enzyme that affects melanin production. The enzyme is sensitive to heat and becomes active in cooler areas of the cat’s skin, causing dark coloration in those parts of the body.

In the beginning, most Siamese cats had dark brown points known as “seal,” but sometimes they were born with lighter brown, cool grey, or pale warm gray points. Initially, anything other than “seal” was seen as less desirable and not suitable for showing or breeding.

Over time, the different colors of Siamese cats were recognized and approved by breed associations. As a result, these colors became more common in breeding programs. This led to the development of various patterns, such as red and cream point and tortoise-shell point, which gained popularity among cat enthusiasts and experts.

Many Siamese cats from Thailand used to have a bent tail, which was seen as a defect by some people and still is today. Nowadays, most breeders have eliminated this trait, but it can still be found in certain areas of Thailand.

Siamese Cat Personality

Siamese cats are loving, smart, and super friendly. They love being around people and stay playful even when they grow up. They act more like dogs than other cats.

Siamese cats can experience feelings of sadness if they are left alone for extended periods of time because they enjoy being around people. To address this issue, people often choose to purchase two Siamese cats instead of just one.

A key characteristic of Siamese cats is their tendency to be vocal and expressive. They communicate using a loud, raspy voice and desire attention from people. They often accompany individuals and appear to be overseeing their every action.

Longevity and Health

Unfortunately, Siamese cats have a higher mortality rate compared to many other cat breeds. On average, Siamese cats live for about 11 years, although this can vary. This lifespan is relatively short compared to other breeds, which often live into their mid to late teens, and some even reach their twenties if they lead active and healthy lives. Siamese cats are prone to various health issues, including tumors and gastrointestinal problems.

Siamese cats have blue eyes because of a genetic mutation that also causes their colored points. However, this mutation means that they lack tapetum lucidum, which helps other cats see in dim light. Unfortunately, these health problems are common in Siamese cats.

Popular Siamese Cats

If you have a Siamese cat, you’ll have many happy years ahead with a beautiful and attention-seeking pet. Siamese cats are well-known for their unique appearance and charming personalities, making them beloved figures in popular culture. Some famous Siamese cat icons include:
