Siamese Cat Life Cycle & Growth: Caring for Kittens, Adults & Seniors

Ultimate Siamese Cat Life Cycle Guide


Siamese Cat Life Cycle

The Siamese cat is an amazing cat with a rich history and one of the oldest known breeds of cat. These cats have many aspects to their appearance and personality, ranging from their cream-colored coats to their cerulean blue eyes and their vocal disposition.

 They are also known for being one of the most intelligent breeds of cat around, able to understand concepts that most cats would find too puzzling or boring to care for.

Choosing to adopt a Siamese cat is a choice that should have some thought put into it, as should all decisions that involve taking in the care of any animals. 

Naturally, this means that you should work on researching what you should expect, especially if you are raising a newborn Siamese cat.

What to Expect as Your Siamese Cat Grows Up

First things first; you should have a sense of what you should expect when your Siamese cat is done growing. 

All cats grow at slightly different rates, so it can sometimes be more helpful to know what to expect by the end of the growing period rather than stressing over which specific growth period your Siamese cat is in.

How Big Do Siamese Cats Get?

The Siamese cat itself is a moderately sized cat with a sleek coat that doesn’t add much to its size. Most male Siamese cats will weigh between 9 and 13 pounds, or about 4 to 6 kilograms. Some Siamese cats may be heavier-set than others or may be skinnier than others, but this is the general weight range for a male Siamese cat.

The female Siamese cat is a fair bit smaller, with an average weight between 5.5 and 10 pounds, or between 2.5 and 4.5 kilograms. Likewise with their male counterparts, some female Siamese cats may be slightly larger or smaller than this, but this is the expected weight range for a fully grown adult female Siamese cat.

How Tall Do Siamese Cats Get?

Interestingly enough, the height of the Siamese cat does not show the disparity between size the way that weight does, leaving most female Siamese cats to appear skinnier and sleeker than males, depending on how the cat carries the weight. Siamese cats of both genders share a similar height range, with that being between 10 and 12 inches high, or between 27 and 31 centimeters in height. Males will often not be quite as short as females can get, but there may be some outliers that are somewhat short.

How Long Do Siamese Cats Live?

Siamese cats are known to have one of the longer lifespans of most purebred cats, partially because of how long these cats have been around. They have a natural lifespan range of between 15 and 20 years, with some people knowing their cats to live beyond this range. 

Keep in mind that it is relatively rare for cats, especially purebred cats, to live beyond 20 years so you should not expect this of your Siamese cat. This does, however, go to show that these cats are a robust breed that will stick with you for decades to come.

How Do You Know When a Siamese Cat is Full-Grown?

A full-grown Siamese cat, or a Siamese cat that has stopped having its fur change color, will typically have the traditional Siamese coloring pattern of white or off-white fur with dark brown or black markings on the tail, legs, face, and ears. 

One thing to keep in mind is that there are certain subsets of the Siamese cat breed because of how long it has been around, and there are some differences in how these cats change compared to the Modern Siamese that most people are used to.

The Thai Siamese cat is the second most common kind of Siamese cat, and it is slightly larger and fairly heavier than the standard Siamese cat and tends to live slightly longer. Aside from this, they are much the same.

Caring for a Newborn Siamese Kitten

While most places that adopt cats or sell them will not sell kittens under a specific age, as it can cause problems due to the kitten being taken away from its mother, you might find yourself in a situation where you are caring for a newborn Siamese cat. 

During this stage of life, it is almost always best to leave the kitten in the care of the mother cat, if that is possible. Much as with human babies, kittens rely almost entirely on their mothers for the first stages of life.

Siamese Kitten Eyesight

As with all kittens, Siamese kittens are born blind and without their sense of smell. They tend to open their eyes between 6 and 10 days after birth, and by two weeks of age, will be able to fully rely on their sight. Because of this, kittens rely entirely on their mother’s mews and chirps to squirm around until they learn how to walk. 

The mother cat will be responsible for feeding and nourishing the kittens as well as protecting them. During this first stage of life, Siamese kittens aren’t too different than other newborn cats.

Siamese Kitten Fur & Eye Color

Typically around the end of your kitten’s first week of life, you will see coloring develop. All Siamese cats are born with some genes being related to albinism, and this is why these cats are born without their usual stark coloring. 

All cats will progress differently, but they will typically obtain their coloring starting at roughly three weeks of age and progressively intensifying until the kitten reaches one year of age.

The pattern of the Siamese is known as “point coloring” as all the “points” of the cat are what is colored. The points are the legs, nose, tail, and ears of the cat. 

A unique feature of Siamese cats is that, unlike other cats, they keep their blue eyes all throughout their life.

Siamese Kitten Temperament & Vocalizations

Depending on whether or not the mother is a large part of your kittens’ life yet, you will find that newborn Siamese cats are surprisingly demanding. 

From a young age, they use their wide range of vocalizations to get what they want, when they want, and this is all the more true for the youngest kittens. Siamese cats will typically start to mewl from a very young age and as they grow up, they will turn these sounds into more concrete vocalization, ranging from bold meows to chirps and everything in between as they learn how to talk with you.

How to Feed a Siamese Kitten

Again, the care for a newborn kitten should typically come from the mother cat. If the mother cat is not present or is unable to care for the kittens, then you will have to take on this role, which can be complicated. 

Thankfully, there are many guides to properly feeding newborn kittens until they are of an age they can begin eating solids.

Siamese Kitten Growth Rate

Baby kittens will begin growing at an exponential rate, much the same way that human babies do. By the second week of life, they should be double the size they were at birth. They should begin to teethe and their ears should begin pointing up. It takes about five weeks for Siamese kittens to really show their personality beyond the first stage of life.

Siamese Kitten Learning and Play

This is also the point in time where their intelligence begins to shine. They will want to play, explore, and learn how the world works far more than other cats would, and this is an optimal time to begin training your Siamese kitten, if you are interested in doing so. 

Siamese cats are capable of learning a number of different tricks and the younger you begin teaching the cats, the better they will be able to grasp the concept of training before the standard aloof attitude of cats has time to set in.

Further Development

By about eight weeks, you should be able to get a good sense of not only the color points of the coat, but exactly what variation and color they will develop into. The full strength of the coloration may not have developed quite yet, but it should be easily noticeable. 

Between 5 and 13 weeks is the best time for kittens (of all types) to be introduced to people rather than only the mother.

This is also around the time the kitten should receive its vaccinations. The exact time does not matter as long as it is before five months of age, which is when Siamese cats reach sexual maturity. At this point, you need to consider getting the cat fixed, unless you are looking for more kittens.

Developing From a Newborn to a Baby

Cats are considered babies from about six months to two years of age. 

They will be more mature, be more curious, and have more energy than they were before this age. After about two years, they will settle down into their more adult personalities. 

Young Siamese Cat Eating Habits

By this point, your kittens should be on kitten food and you should see their temperaments develop. Keep in mind that Siamese cats are known for being incredibly picky about food, so it might take a few tries to get the right kind of food.

Developing Their Signature Fur Color

As they draw closer to the one-year mark, they should have developed their full coloration. The main body of their coat should be a rich white, cream, or off-white color that relates to the coloring of their points. 

Siamese colors can range from blue, chocolate, and lilac to more exotic colors such as red, cinnamon, and apricot. Their main body of fur will often have tinges of this color throughout, often close to their legs and tail.

At this age, their coloring should be fully developed, encompassing their paws, tail, snout, and ears. You shouldn’t expect much else in terms of coloration after the one-year mark, aside from age-related greying of the fur as the cat approaches 15 years of age.

Growing Sassy

This is also the time that Siamese cats develop their energy and attitude the most. They will demand your attention, even emitting cries that aren’t dissimilar to baby cries if you don’t give them your full undivided attention. You can make use of this energy through training, tricks, and other mentally stimulating activities that really show off how smart Siamese cats are.

If there are multiple people in the house, there’s a good chance that the Siamese cat will latch onto one person as a “favorite” and bug that person the most, and may even become jealous if you spend time with the cat’s chosen person. 

If the cat is too persistent in its jealousy, this is also the best age to work on training out unwanted behaviors, so notice how your cat acts when you aren’t with it.

Caring for an Adult Siamese Cat

Your Siamese cat will likely mellow out somewhat once it reaches about two years of age. To put it in human equivalent years, this is about the time your cat would be out of school and looking for jobs, settling down in a house, and so on. 

It is simply the stage of life where your Siamese cat will not be so full of wild energy and will be calmer.

Keep in mind that Siamese cats are still vocal, clingy cats even if they aren’t showing it quite as much as they otherwise would. 

They can still get sad and depressed if they aren’t played with enough, and it might be even harder to see that as their aloof attitudes set in. 

They will, however, be much more tolerant to letting new people into their lives and even letting new people spend time with their chosen person.

This is a good age for large life changes to happen, such as moving households. At this age, your Siamese cat will still enjoy activities, toys, and plenty of other mentally stimulating objects. Chances are that your cat will enjoy these kinds of toys throughout its life, as these cats always seek to have a good time.

Be Mindful of Health Issues

This is also around the age where you will want to be mindful of the health issues that Siamese cats can develop. 

Siamese cats are notorious for poor eyesight, especially in the dark, and you may need to make adjustments to your house to cater to this. As adults, Siamese cats can also develop kidney, bladder, and heart problems that you will need to be mindful of.

Caring for a Senior Siamese Cat

Despite the fact that many Siamese cats will live into their early 20s, Siamese cats are considered to be seniors once they reach the age of 10. 

Senior cats, much as with senior people, can’t move around as easily as they were once able to. Because Siamese cats love to jump high, you may find that you need to move toys and activities a bit lower for an older senior cat to get the most out of them.

Senior cats will often be even more mellow, opting to take more naps and not always wanting to play. You should make sure to still provide enrichment if your cat wants it. 

Be mindful that senior Siamese cats are far more prone to stressors, especially sounds and new people, and that they are more at risk of developing kidney conditions.
