How Long Do Siamese Cats Live?

Siamese cats tend to live fairly long lives compared to other cat breeds. I’ve had two Siamese cats in my life, and they both lived longer than any of my other cats — one was 18, and the other was nearly 20 years old. How long do Siamese cats live typically?

Siamese cats live about 15 to 20 years on average. Siamese cats have a long average lifespan, being one of the sturdier and healthier breeds of cats. The length of their lifespan depends on many factors, including genetics, whether it is an outdoor or indoor cat, diet, and exercise.

Read on to learn more about Siamese cats, where they come from, how long they live, and what we can do to make them live longer.

What Are Siamese Cats?

Siamese cats are one of the well-known cat breeds. One of the most iconic portrayals of these cats may be from the classic film Lady and the Tramp. They have very distinct features that can help identify them from the other cat breeds.

These felines have light fur, ranging from white to cream color. As they grow older, their light hair can darken. Their body is elongated, muscular, and slender. They also have dark parts in their fur called points. These include their face, ears, and extremities.

These points are of the same color and can range from chocolate to lilac. They are also easily distinguished by their facial features; they have blue-almond eyes, large ears, and triangular faces. They are also very vocal, having a unique voice.

Siamese cats are one of the oldest cat breeds. There are many speculations regarding this cat breed’s origin. One of the earliest mentions of this cat breed is from an ancient manuscript in Ancient Siam, now called Thailand, dating between the 1300s and 1700s.

It describes a pale cat with a dark face, dark ears, and dark feet. During that time, people believed that these cats are as rare as gold, and having one can make you wealthy. Due to the discovery of the manuscripts, many believed that the Siamese breed came from Thailand.

The company of the lovable Siamese cat breeds can now be enjoyed as common house pets. And as owners of these beautiful cats, we want them to live as long as they can. So what are the factors that can affect their lifespan? What can we do to make our cats live longer?

What Factors Affect How Long Siamese Cats Live For?

how long does a siamese cat live

Asian cat breeds, such as the Siamese, tend to live longer than most breeds. They live typically up to 20 years, and commonly even more than 20 years, given the right conditions and care. A Siamese cat named Scooter holds the Guinness Book of World Records for being the oldest tomcat (male cat), dying at the age of 30.

Here are some factors that can influence cats’ lifespans, including the Siamese.


In general, purebred cats tend to live a shorter life than crossbred cats. Purebreds are more susceptible to diseases. This is the side effect of many years of selective breeding. According to a study conducted by the Royal Veterinary College, the average lifespan of purebred cats is 12.5 years, while the typical lifespan of crossbred cats is 14 years.


A cat’s longevity or lifespan is also largely determined by their genetics, just like any other living creature. If your cat’s parents live a long life, your pet would likely be the same. Unfortunately, your pet can also inherit certain conditions from their parents, such as heart disease and asthma. 

Outdoor or Indoor Cats

Outdoor cats are more prone to the dangers outside than indoor cats. These risks include car accidents, pollution, diseases, and other animal attacks. In the UK, car accidents are the top cause of death in cats under one-year-old. Despite the risks, some owners and veterinarians believe that outdoor cats live a more interesting life, and keeping them inside all the time is too cruel.

Deciding whether you want your cats to be indoor or outdoor depends on your preferences. Before deciding, take careful consideration of the place where you live, whether it is safe for the cat to be outside or not. Also, it is always a good idea to seek the advice of a veterinarian.

Even if you decide to keep your Siamese cat indoors, you can make a space for them to roam. You can even train them to walk with a leash, just like dogs. That way, your feline can still enjoy outside activities while minimizing the risks.

Overall Health

The biggest factor that can affect how long Siamese cats live is their overall health. Siamese cats are a naturally healthy breed. However, as most pets do, they require frequent check-ups with the veterinarian.

Read on to learn how can we, as pet owners, promote good health for our cats, so they live as long as possible, to age 20 or longer.

What Can I Do to Make My Siamese Cat Live Longer?

As with any other pet owner, we love our pets very much, and we want them to live for as long as they can. Fortunately, there are many things we can do to help them live a longer life.

Proper Diet

Obesity is an all-too-common health problem among cats, including Siamese cats. On average, an obese cat will live up to five to ten years fewer than a normal cat. Promoting a healthy and nutritious diet for your Siamese cat is the best way to help them achieve a better quality of life. The Siamese breed is also prone to dental problems. Poor dental health will reduce their quality of life and, therefore, potentially lead to a shorter life.

Regular Exercise

Siamese cats need regular exercise, just like all cats do. Most of them like to stay indoors, making them less active than most cats. To keep them fit, regularly encourage your pets to play, run, jump, and stretch. It’s also possible to train your cats to do walks as dogs do.

Give Them All Your Love

Siamese cats are friendly and crave attention. They like to spend time with their loving owners. Not spending enough time with them can make them depressed and destructive. This often leads to complications that can shorten their lifespans. So show them some TLC, and they will stay longer with you.

Common Health Problems Among Siamese Cats

How long a Siamese cat lives depends on many factors. Despite their sturdiness and longevity, they could still develop health problems which could shorten their life. Like any other purebreds, Siamese cats can suffer from serious conditions resulting from years of inbreeding.

Detecting and preventing these complications can help lengthen their lifespan considerably. Here are some of the common health problems that your cats can develop as they grow older.


Amyloidosis is a genetic disease that is more prevalent in Siamese cats than any other cat breeds. The condition occurs when a substance of folded proteins, called amyloids, is deposited throughout the parts of the body. This can damage the normal cells in the cat’s body. This condition can lead to serious complications, such as liver damage and internal bleeding.

How can you detect amyloidosis? The symptoms of this ailment are similar to progressive liver damage. This includes lethargy, weight loss, poor coat quality, inflammation of the gums, and excessive drinking and urination. It can be confirmed by checking the number of amyloids in the liver. Consult a veterinarian if you suspect that your cat is suffering from amyloidosis.


Cancer is one of the top causes of death among middle-aged and older cats. Cancer can be treated as long as it is detected early. The most common type of cancer that Siamese cats suffer from is Lymphoma. This causes the body to form abnormal white blood cells. This condition is fairly easy to detect through blood-testing.

Siamese cats can also suffer from adenocarcinoma. It’s a form of cancer in which tumors grow around the intestine. When the tumor gets bigger, it can restrict the natural flow of the digestive tract, leading to multiple complications. 

To avoid and prevent the risk of cancer, it’s best if your feline friends undergo a medical examination every two or maybe three years. It’s also recommended to have their blood tested every year.

Respiratory Diseases Such as Asthma

Asthma is a deadly condition common even among cats. Cats with asthma suffer from chronic inflammation of their respiratory tract. During asthma attacks, your Siamese cat may find it very difficult, or in some serious cases, impossible to breathe.

Common signs of asthma are wheezing, heavy breathing, and persistent cough. Schedule a visit to the veterinarian’s office once you notice these signs so that they can give the proper treatment for your cats.

Behavioral Disorders

Socializing is a must for breeds like Siamese cats. Not having enough time to socialize with others can cause depression and other behavioral disorders. Stress-out cats can further develop compulsive disorders, such as psychogenic alopecia. Cats with this condition over-groom themselves, and a bald patch is often an obvious sign.

To avoid these problems, regularly interact with your pets. Encouraging them to play can also help to prevent such conditions.

Siamese Cat Diet for Long Life

A healthy diet always contributes to a long and good quality of life. For our beloved Siamese cats, giving them the right kind of food is crucial to their longevity. Here are the things you can feed your cat to make them live to 20 or more years.

Dry Pet Feeds

There are various feeds for cats depending on their age. For Siamese kittens, it’s best to go with high protein and high-fat food. They will also require food with vitamins and calcium. This can help them to become strong and healthy as they go.

For adult Siamese cats, well-balanced feeds are recommended, preferably with fiber and omega fatty acids. As for older cats, it’s recommended to cut the fat and the protein to a minimum, as they don’t need them as much as when they were younger.

Canned and Wet Food

Canned and wet food is also suitable for Siamese cats. However, veterinarians strongly advise against feeding your pets canned food too often. Too much of this can cause dental problems and can affect their digestive tracts. Issues with their digestive tracts can shorten their life, depending on how severe the issue is.

If you’re going to feed your cat with canned foods, make sure they have high protein and low carbs. It should also contain essential vitamins and minerals, such as iron, potassium, and calcium.

Homemade and Fresh Foods

A portion of homemade and fresh food is a good addition to your cat’s diet. Siamese cats love meat that is rich in protein and fat, such as turkey, ham, salmon, and chicken. Always cook the meat properly before giving them to your feline companion. Cats can also eat fruits but do not feed them too much.

Ideally, your cat should eat a combination of these three food types. Their diet should mainly be composed of food rich in fat and protein. Omega-6, Omega-3, potassium, iron, calcium, and taurine will also do wonders for your cat’s health and make them live as long as possible.

As they grow older, you can feed them less protein and fat, as they no longer need those nutrients as much as they did.

These are the foods that they can eat, but what food shouldn’t you give to your cat?

Foods to Avoid When Feeding Your Siamese Cat

When choosing what to feed your Siamese cat, there are a few foods that you should watch out for. The following foods should be given with caution or not at all in order to maximize the life of your Siamese cat.

High Sugar

Feeding your Siamese cat with food high in sugar can cause some complications such as diabetes and obesity. It could also affect their dental health. Cats can sometimes eat fruit, but avoid overfeeding them as most fruit contains a lot of sugar.

Avocado and Grapes

Certain kinds of fruits can be harmful to cats. Avocados contain Persin, a substance that can cause vomiting, diarrhea, and poisoning to most household pets. Consumption of avocados can be very fatal to your pets, including dogs, birds, and cats. Grapes and raisins can also harm your pets, causing kidney problems in cats.

Excess Carbohydrates

Cats are carnivores, mostly meat-eaters, so they do not need a lot of carbohydrates. Carbohydrates are a common source of energy, but not with cats. Their bodies, like other carnivores, cannot fully use carbohydrates as an energy source. As a result, consuming too many carbohydrates can cause obesity and digestive problems in cats.

Garlic and Onions

Garlic, onion, and herbs can cause gastrointestinal irritation in cats. This can lead to a more serious problem, like red blood cell damage. Occasional small consumptions, whether from the snacks they eat or the food they consume, will likely have no adverse effects. However, feeding them large quantities can pose a serious health risk.

Caffeine and Chocolate

Coffee and Chocolate contains a substance called methylxanthines. When ingested by pets, they cause vomiting, diarrhea, and excessive urination. When cats ingest large quantities of methylxanthines, it can cause serious medical problems, such as abnormal heart rhythm, seizures, and even death.
