Siamese cats are naturally skinny. The average weight of a male Siamese cat is between 8 – 12lbs with female Siamese cats weighing less at 7 – 10 lbs. Fully grown Siamese cats weighing less than 7 pounds may have underlying health issues contributing to their low weight.

It can sound like a lot of work to manage your cat’s weight, but that doesn’t mean it has to be a chore for you. We can all use more information about a healthy weight for your Siamese cat, so you can learn more if you keep reading!

How Much Should A Siamese Cat Weigh

Siamese cats have a different weight depending on whether they are male or female, but all Siamese cats should weigh between 7-12 pounds.

Male Siamese cats are larger than female Siamese cats, but only a small difference between the genders.

A full-grown, adult Siamese cat about two years old should weigh anywhere from 7-12 pounds at a healthy weight. 

Cats will fluctuate between this scale, and you should only be concerned as your cat starts to dip below 7 pounds or go above 12 pounds.

What Is A Good, Healthy Weight For A Cat

As you can see from the section above, it isn’t easy to know precisely what a good, healthy weight for a cat is.

Your cat’s weight depends on various factors, like cat breed, age, sex, size, and activity level.

Cat breed is an essential aspect in knowing if your cat is a healthy weight.

A Siamese cat will be lighter than a Maine Coon cat or another kind of cat breed.

There is also no one particular weight that a cat should be. If you are looking to see how heavy your cat should be, you’re going to see a scale that can span more than a few pounds. 

If your cat goes above or below what is known as a “healthy” weight, you should speak to your vet before making any drastic changes to your cat’s diet. 

Siamese Cat Weight Chart By Age

Siamese cats will have different weights based on their age, so let’s look closer at that in the following chart:

Kitten1-4 pounds over the first few months of life; Kittens will gain weight fast as they grow
Adult7-10 pounds (Female) 9-12 pounds (Male)
SeniorGenerally the same as Adult; Weight may go up as your cat becomes less active with age

Kittens are going to be the age group that your cat is going to start quickly gaining weight. Your cat will not stay a pound for more than a few weeks. 

By the time your cat is an adult, you will usually not see a significant fluctuation in your cat’s weight because they are already fully grown.

Why Is My Siamese Cat So Skinny

Siamese cats are naturally skinny, but your Siamese cat should not be too skinny.

It can be challenging to know what it means that a cat is skinny but can’t be too skinny unless you’re an expert on the cat breed.

There are a few reasons why your cat may be too skinny, including

Thyroid issues

Thyroid issues are a leading cause when it comes to cats being too skinny. The thyroid hormone is produced in the thyroid glands. When a cat is dealing with Hyperthyroidism, they actually end up with too much thyroid hormone. This can in turn cause issues like weight loss; sometimes rapidly.

This situation is more present if you have an older Siamese cat; not as much in younger cats. Hyperthyroidism typically affects cats that are 10 years or older. The only way to know if this is the true issue is to get your cat’s blood levels tested. The test will look for elevated levels of T4.

Not liking the food that you’re buying

Siamese cats can be finicky sometimes; especially when it comes to their food. If you notice your cat’s weight loss started after a food change, then they probably don’t like the food. They may nibble at it at best, and in some cases not eat it at all.

This is more present when taking a cat off of a primarily wet diet and transitioning to dry food. Dry food might be more convenient to feed, but once a cat gets hooked on it, it’s tough to make that change.

Your cat has some issues with his teeth

Health issues with the teeth can cause cats to eat less due to pain. This includes tooth sensitivity, tooth decay, and general soreness in the mouth area. While a cat will still try to eat, the entire process is simply too painful for them.

Have a look at your cat when they attempt to eat. Are they meowing and chewing slowly? Has the weight loss been a recent event?

You need to feed your cat more food than you are currently giving

You might be surprised, but it’s not uncommon to underfeed your cat. It’s best to follow the labels on the food packaging, but even in those situations, you might still find that you are underfeeding your cat.

Things to consider are your cat’s current weight, age, and length. Generally, male cats are going to need to be fed more than female cats. In addition, your cat should be fed multiple times per day (unless they are free-fed).

Your cat likes to be active and is burning too many calories

Hyperactive cats tend to have a problem with weight. Their daily activities might include too much play and as a result, they burn off all the food they consume. In this case, you’ll want to limit your cat’s playtime when you notice it getting out of hand.

The food you purchase your cat doesn’t have the best quality ingredients for your cat

Cheap food might be a good idea for the pet owner, but it’s terrible for your cat. Cheap food is usually filled with cheap ingredients. Rather than quality proteins, your cat is instead of eating tons of food with fillers. It’s essentially empty calories that do not give your cat the nutrients it needs for the body to function properly.

If you find that you are struggling to manage your cat’s weight by yourself, you should seek help from your vet.

Can Siamese Cats Get Fat

Siamese cats, like any other cat, can get fat.

Nothing in a Siamese cat breed prevents them from getting fat, even though most Siamese cats that you see are usually skinny.

As Siamese cats get older, they will become less active, which means a higher chance of becoming fatter.

Young Siamese cats will also be fatter than lean, healthy adult cats because they grow so quickly. This is similar to the baby fat that humans have when they are younger.

One of the easiest ways that Siamese cats get fat is by leaving cat food out all day. Your cat can begin overeating during the day if the food is unrestricted.

How To Make Your Siamese Cat Fat

Although some cats can stand to gain more weight, it should never be your aim to make your Siamese cat fats.

Since cats are relatively small animals, additional weight can negatively affect your cat’s health very quickly. 

If your cat can stand to gain a little more weight to make him healthier, here are some things you can try:

  • Feed your cat more often, especially if you find that he does not like to eat large meals.
  • Give him some more treats. These are not healthy nutrients, but they can help your cat gain some weight. 
  • Find proper food for your cat. You may be able to find cat food with a high protein content that will allow him to gain more weight. 
  • Speak with your vet. Underlying medical issues, like thyroid disease, can be causing issues with your cat. If so, medication may be the way to go. 

Is It Necessary To Manage A Cat’s Weight

It is not necessary to manage a Siamese cat’s weight, but it can be helpful if you find that your cat is either too skinny or too fat. 

For the most part, cats stay a consistent weight through much of their adult life. 

Barring any medical conditions, your cat’s weight will not fluctuate as easily as a human’s weight can. If your cat’s weight does change, it will only be by a pound or two.

It will become necessary to manage a cat’s weight as they get older. 

Older cats are not as active as younger cats, which can mess up their routine. They are playing less and eating the same amount of food as they did when they were younger. 

Much of the time, cat food can be enough to help you manage your cat’s weight, but you may also need to play an active role in increasing your cat’s activity level.

What Is An Unhealthy Cat Weight

An unhealthy weight can look different for different cats, but two or three pounds above or below their target weight of 7-12 pounds can be considered unhealthy for Siamese cats. 

A Siamese cat below weight at 4-6 pounds can struggle to get proper nutrients. Their fur may not be as shiny, and they might not have as much energy as other Siamese cats.

Most people think of overweight cats as a bad thing but being below weight is not good either. 

On the other hand, it can also be unhealthy when a Siamese cat is above its ideal weight. 

Being overweight has many more common risks associated with it, such as diabetes and heart disease.

Do not automatically believe that higher weight is bad, though. For instance, a male, muscular Siamese cat may be heavier than the bracket because they have more muscle than other cats.
