Bringing a new cat into your home is a significant decision, and choosing between a male or female cat is one of the first considerations for many prospective owners. Understanding the differences between male and female cats can help you make the best choice for your lifestyle and household. This article explores common questions and perceptions surrounding male and female cats to help you decide which gender might be the purrfect addition to your family.
Neutered Cats of Both Sexes: Equally Wonderful Companions
Let’s clarify some key terms right away. Throughout this discussion, we’ll be focusing on cats that have been neutered (males) or spayed (females). These procedures, technically known as gonadectomies, significantly alter a cat’s behavior compared to intact, or unneutered, cats. Intact cats retain their reproductive hormones, which heavily influence their behavior.
Neutering male cats involves removing their testicles. This simple surgery leads to a reduction in aggressive tendencies, less urine spraying, and a decrease in sexual behaviors (1). Unlike female cats, intact males do not experience heat cycles, but their drive to find a mate is constant if they are not neutered.
Spaying female cats means removing their ovaries and uterus. Spaying results in less aggression and stress in females compared to unspayed counterparts (2). Crucially, spaying eliminates heat cycles, preventing the characteristic yowling and attempts to attract male cats to your home.
Cats that have undergone neutering or spaying are generally more affectionate towards humans (3). They also have a lower risk of developing certain health issues. Therefore, both neutered male and spayed female cats make considerably better pets than intact cats of either sex.
Affection Levels: Is There a Gender Difference?

Popular belief and anecdotal accounts (4) often suggest that male cats are more affectionate and friendly. However, when we look at natural feline behavior, female cats might be inherently predisposed to affection in different ways.
While male cats in the wild tend to live solitary lives, patrolling their territories, female cats exhibit strong maternal instincts and a tendency to live communally when resources are plentiful (5). In these colonies, they collectively care for kittens and are known to stay close to their human companions, especially when they sense illness or distress (6).
A research study analyzing personality traits in 196 cats investigated factors like friendliness, sociability, and independence across genders. The findings indicated that sex was not a significant determinant of a cat’s personality (7).
Early socialization plays a far more crucial role in a cat’s affectionate nature. Kittens that are not regularly handled and socialized with humans between the ages of 2 and 7 weeks are less likely to develop into friendly and affectionate companions (8). This holds true regardless of their genetic predisposition. Friendliness is indeed a heritable trait in cats (9), meaning kittens of friendly parents are more likely to be friendly themselves.
Therefore, when seeking an affectionate cat, focusing solely on gender is less important. The key factors are the quality of their early socialization with humans during their first two months and the inherent friendliness of their parents.
Breed also significantly impacts a cat’s potential for affection. Certain breeds, like Ragdolls and Persians, have been selectively bred for their gentle and affectionate temperaments.
Aggression: Are Female Cats More Likely to be Aggressive?

Aggressive behavior is certainly undesirable in a pet cat. There’s a common misconception that female cats are inherently more aggressive than males, making them less suitable as family pets. However, a study examining the behavior of 120 domestic cats found no significant difference in aggressive behavior between male and female cats (10).
This same study highlighted considerable variations in behavior among individual cats, suggesting that personality traits are more influential than gender when it comes to aggression. Individual temperament, therefore, appears to be a stronger predictor of aggressive tendencies than sex.
The idea that female cats are more aggressive might stem from observations of unspayed females. Female cats in heat or protecting their kittens are naturally more defensive and reactive. However, unneutered male cats are equally prone to aggression, particularly towards other male cats. Regardless of gender, ensuring your cat’s safety when outdoors is paramount. A breakaway cat collar is an excellent safety measure, allowing them to explore while minimizing risks.
In conclusion, as long as your female cat is spayed, she is no more likely to be aggressive due to her sex. Genetics and breed, alongside early experiences, play a more significant role in determining a cat’s likelihood of aggression.
Negative early experiences or a lack of socialization with humans and other cats can contribute to fearfulness and aggression. Other factors that can increase aggression include early weaning (11) and the use of punishment by owners.
Size Matters? Comparing Male and Female Cat Size

Male cats tend to be slightly larger than female cats, even when neutered early in life. Female cats typically reach their adult weight around 13 months of age, while male cats continue to grow until approximately 16 months old. During growth, female cats generally require less energy than males (12), meaning they may need slightly less food.
However, the size difference between adult male and female cats is not dramatic. Both genders typically stand around 8 to 10 inches tall. Breed and diet quality are more significant factors influencing a cat’s size. Inadequate nutrition or early weaning can also lead to stunted growth, regardless of sex.
One noticeable difference is that male cats often have broader faces. Testosterone contributes to facial rounding, giving male cats, especially unneutered toms, a characteristic “tom-cat” look with puffier cheeks and a larger head. Male cats neutered later in life may retain this more pronounced head shape.
Coat Color: Is There a Gender Link?

Female cats are often associated with more diverse and interesting coat colors, particularly tortoiseshell patterns. This is due to the genetics of feline coat color, where the orange color gene is located on the “X” chromosome. Female cats have “XX” chromosomes, while males have “XY”. Having two “X” chromosomes allows female cats to express unique combinations involving orange coloration.
Tortoiseshell cats exhibit a patchwork of two colors, typically orange and black, resembling a tortoise shell. Calico cats are a type of tortoiseshell with the addition of white patches, creating a tricolor coat.
The presence of two “X” chromosomes is necessary to produce a tortoiseshell or calico pattern. Therefore, almost all tortoiseshell and calico cats are female. However, in rare cases, a male cat can inherit a triple chromosome combination “XXY”, known as Klinefelter syndrome, and can be a calico – making them a genetic rarity!

While regular male cats can be orange, as they possess one “X” chromosome, they typically don’t display the complex orange patterns seen in tortoiseshells and calicos. Orange male cats are usually solid orange tabbies.
Multi-Cat Households: Do Males or Females Integrate Better?

If you already have a cat at home, choosing a new cat that will harmonize with your current feline companion is crucial. Fortunately, neutered and spayed cats are generally much more accepting of each other than intact adult cats.
Female cats often exhibit greater tolerance towards new cats entering their territory. They are typically more receptive to another female cat than to a male cat. In feral settings, domestic female cats form colonies when food resources are sufficient. They live in groups with related females, sharing resources and cooperative kitten rearing responsibilities (5).
Male cats, in contrast, are solitary creatures in the wild. They roam individual territories and do not naturally form male groups. Occasionally, males may be tolerated by female colonies within their territory and may visit, but they do not engage in positive social interactions with other intact males.
Therefore, if you already have a cat of either sex, introducing a new female cat might have a higher chance of success. However, compatibility is not guaranteed.
Neutered male cats behave much more like female cats in terms of social dynamics than like intact male toms. This makes peaceful cohabitation between a neutered male and a spayed female cat possible.
Regardless of sex, cats are more likely to bond if raised together from a young age. Early co-socialization is more significant than gender. Adopting littermates is ideal. Introducing unrelated kittens can also lead to strong bonds and harmonious relationships.
If adopting bonded pairs or littermates isn’t feasible, inquire about a cat’s past living situation. Previous positive socialization experiences are a good indicator of a cat’s ability to get along with other cats.
Genetics also contribute to a cat’s sociability with other felines. These factors, including early experiences and genetics, often outweigh gender in determining a cat’s social compatibility.
