Siamese Cat Gender Differences: What You Need to Know

When it comes to Siamese cats, gender can play a significant role in their appearance, personality traits, training, and health. While both males and females can make wonderful pets, there are some key differences to consider before bringing one home.

1. Appearance


One of the most noticeable differences between the two genders of Siamese is the cats size and appearance. In general, males tend to be larger and heavier than their female counterparts.

  • Male cats typically have a more substantial build, with a heavier body (8-13 pounds) and a larger overall size (11-13 inches tall).
  • Females, on the other hand, are generally more petite and have a sleeker On average, they measure 10-12 inches tall and only weigh 5-10 pounds.

To determine the sex of your Siamese feline, examine their genital areas. Female cats have a vertical opening, while males have a round opening with a wider gap between the anus and genitals.


2. Personality Traits


One known Siamese cats’ personality is that they’re generally talkative. However, there are some key differences between the two genders.

  • Male Siamese cats are generally more outgoing and affectionate. They tend to be more vocal and demanding of attention. And as they love companionship, they can get on well with other pets and kids.

Note that if left unneutered, they will become aggressive when in heat and may even escape the house to find a mating partner.

  • Meanwhile, the females of this breed are more reserved and independent. You can expect them to be content with simply being in the same room as their owners.

Even when not in heat, unspayed female cats can be rather noisy. When breeding season comes, they will become drastically more vocal and moody if unable to find a mating partner.

3. Training


Despite their playful and affectionate disposition, male Siamese cats may display a slightly more assertive and territorial demeanor. However, consistent and patient efforts can instill positive behaviors.

For female Siamese cats, training is generally uncomplicated due to their laid-back and obedient nature. Their innate intelligence allows for quick learning, making boundary-setting and training efforts highly effective.

In other words, female Siamese cats often exhibit natural good behavior, contributing to a more seamless and enjoyable training experience.

4. Health and Lifespan


The average lifespan of Siamese cats is 15-20 years, regardless of gender.

They can both develop certain health conditions like retinal atrophy, vestibular disease, and respiratory infections. In addition, they may have mental issues like separation anxiety, particularly in males, and obsessive-compulsive disorder.

Other than that, this breed is susceptible to gender-specific health problems.

  • Unneutered male cats may have testicular cancer, unitary tract infections, and cystitis.

Once unneutered, the pet has a likelihood of becoming obese and getting gum infection.

  • Meanwhile, their female counterparts may be susceptible to ovarian cancer and infection of the reproductive system.

After being spayed, these felines may suffer from post-operative complications and develop the habit of overgrooming.

5. Rarity


Are male Siamese cats rare? Considering that the gender distribution in this breed is nearly 50-50, the answer would be a resounding “no.”

The reason some people think otherwise is because when the breed was introduced worldwide, the majority of the Siamese felines that became famous were females.


Now that you know the difference between male vs female Siamese cats, you will be able to decide which one you’ll adopt. Consider your lifestyle and preferences when choosing, as each cat brings unique qualities to enhance your feline family.

If you have a lot of spare time to spend with your cat, males are usually the better choice, as they thrive on companionship. Meanwhile, busy people will find female Siamese cats more suitable to their lifestyle, considering these felines can do well on their own for a period of time.

Ultimately, the bond you foster with your Siamese cat, irrespective of gender, will be a source of joy and companionship for years to come.
