Fascinating Truths About Same-Sex Behavior In Cats

If you’ve ever caught your male cat mounting another male, or your female cats cuddling and grooming each other affectionately, you might have wondered if cats can be gay.

While this question often sparks amusement online, it’s a legitimate curiosity for cat owners who observe these behaviors in their own homes.

Scientists have studied same-sex interactions across hundreds of animal species, including cats, and found that while these behaviors are real, they don’t necessarily mean cats experience sexual orientation in the human sense.

This article explores the types of behavior that might look “gay” in cats, explains why they occur, and delves into what researchers and veterinarians believe about feline sexuality and social behavior.

What The Scientific Evidence Says

Over the years, scientists have documented same-sex sexual behavior (sometimes called same-sex sexual interactions or SSSB) in a wide range of animals, including domestic cats.

These behaviors include:

• Mounting
• Genital contact
• Courtship-like approaches
• Affectionate grooming

In one feral cat study, male cats were observed mounting other males during the female’s estrus season (i.e., when female cats are fertile). The researchers tested several hypotheses:

• Mistaken identity
• Dominance assertion
• Sexual play
• Outlet for sexual tension

The study concluded that sexual tension and dominance might best explain the behavior in that population.

The frequency, context, and meaning of these observations are very variable – one species may show same-sex behavior as a rare anomaly, another as a consistent social strategy.

Why Do Cats Engage In Same-Sex Behavior?

The evidence is limited, and animals don’t tell us “why” in human language; so, researchers propose several plausible explanations.

None are universally accepted, and many behaviors likely arise from a mix of causes.

1. Mistaken Identity Or Reflex

Some cases of mounting may occur when one cat misidentifies the sex of another, especially if the “target” cat is in heat, or if pheromones are confusing or absent.

This is more likely in outdoor or feral settings.

2. Dominance Or Social Assertion

Mounting may also function as a dominance display rather than a sexual act, asserting rank within social groups.

In situations of competition, one cat mounting another can reinforce hierarchy or status.

3. Sexual Tension / Overflow

Some researchers argue that when a cat is sexually aroused but cannot access a female (e.g., due to neutering, no females nearby, or timing), mounting another male might act as an outlet.

In the feral study above, same-sex mounting occurred mostly during female estrus, when sexual tension was likely higher.

4. Practice Or Play Behavior

Particularly in younger cats, mounting can be part of exploratory or “practice” sexual behavior, not always meant for reproduction but for learning social or sexual cues.

5. Bonding Or Affection

In some species, same-sex interactions serve social bonding (grooming, nuzzling, co-sleeping). Whether this applies strongly to cats is less clear, but in group-living species, same-sex contact sometimes strengthens group cohesion. 

“Gay” Behavior In Cats And What It Means

Both male and female cats have been observed engaging in behaviors that humans might interpret as homosexual or “gay.”

Humans naturally interpret same-sex affection or mounting through a social or romantic lens. In cats, however, these actions usually stem from different instincts.

These behaviors are real, but the motivation behind them is often instinctive rather than romantic or identity-driven.

1. Same-Sex Mounting

One male mounts another male, gripping the neck or attempting to mate. Neutered males may still do this, and it can even occur between two females.

Mounting can have several motivations:

• Dominance display: Cats use mounting as a social signal to assert hierarchy. The cat on top establishes control, especially in multi-cat households.
• Hormonal overflow: Intact males have strong hormonal drives. When females are not available or a male becomes overstimulated, he may redirect that energy toward another male.
• Learned or habitual behavior: Cats that mounted before neutering may continue out of habit, even after hormones subside.
• Play or stress relief: Young or socially anxious cats sometimes mount to release tension, not for sexual gratification.

2. Same-Sex Grooming And Cuddling

Two male or female cats grooming each other’s faces, heads, or backs, often followed by sleeping side by side or intertwined.

Mutual grooming (called allogrooming) is a social bonding behavior, not a sexual one.

Cats use grooming to strengthen relationships and show trust. It’s more common between littermates or bonded cats that share territory.

Ethologists note that grooming releases endorphins, reducing stress and reinforcing social harmony. In the wild, this behavior helps groups cooperate rather than compete.

So, while two male cats grooming might look affectionate in a “romantic” way, it’s a reflection of deep social bonding and trust, not necessarily sexual attraction.

3. Tail Wrapping, Head Bumping, And “Courting” Gestures

Two cats rub against each other, wrap tails, bump heads, or make chirping sounds.

These are forms of social communication, not mating rituals. Head butting and cheek rubbing transfer pheromones from scent glands, marking each other as safe or part of the same group.

Tail wrapping and rubbing simply signal comfort and recognition.

In bonded pairs (whether same-sex or opposite-sex), these displays strengthen familiarity and reduce tension.

4. Female-To-Female Mounting

One female attempts to mount another, sometimes accompanied by vocalizations similar to mating calls.

This behavior is rarer but can occur for similar reasons as in males:

• Hormonal imbalance
• Play
• Dominance

Female cats experience hormonal cycles (estrus), during which they may become overstimulated and show increased physical affection or mounting behaviors, even toward other females.

What About Neutered Cats?

Neutering drastically reduces hormone-driven sexual behaviors, but it doesn’t always eliminate mounting or same-sex affection.

• Some neutered males retain residual testosterone for weeks or months after surgery.
• Cats neutered later in life may retain learned sexual or dominance behaviors.
• Stress, excitement, or environmental triggers can reignite mounting or marking habits in neutered cats.

If your neutered cat humps a same-sex companion, it’s far more likely to be behavioral than hormonal.

Do Cats Have A Sexual Orientation?

Currently, there’s no scientific evidence that cats experience sexual orientation the way humans do.

Unlike humans, cats don’t form romantic or exclusive sexual bonds based on gender preference. Their mating behaviors are guided by hormones, pheromones, and instinctual triggers, not emotional attraction.

Same-sex sexual behavior has been documented in over 1,500 animal species, but in most cases, it occurs for social, reproductive, or dominance-related reasons – not because of consistent, exclusive preference.

In cats, same-sex mounting or affection doesn’t reflect identity; it’s an expression of instinct or relationship dynamics.

When To Be Concerned

Most same-sex behaviors in cats are harmless. However, you should pay attention if the behavior involves:

• Aggression, growling, or biting
• Stress signs like hissing or hiding
• Persistent humping or chasing that upsets the other cat
• Urine marking or territory spraying

If these occur, consult your vet or a feline behavior specialist. Sometimes the behavior is linked to hormonal imbalance, anxiety, or environmental stress rather than sexuality.

How To Manage Same-Sex Mounting At Home

If same-sex mounting or dominance behaviors are causing disruption:

• Distract and redirect: Use toys or play to break up unwanted mounting gently.
• Provide enrichment: Climbing spaces, scratching posts, and interactive play can reduce excess energy or frustration.
• Neuter or spay if not already done: This minimizes hormone-related urges.
• Separate temporarily if tension rises: Short breaks can help cats reset and reduce tension.
• Avoid punishment: Never yell or spray your cat with water since this increases anxiety and may worsen behavior.

Final Thoughts

Cats can absolutely display same-sex behaviors, from mounting and mutual grooming to affectionate companionship. But that doesn’t make them “gay” in the human sense.

These behaviors are rooted in instinct, hormones, and social bonding, not sexual identity.

In other words, your cats aren’t declaring orientation; they’re simply being cats. What looks “gay” to us often reflects dominance, affection, or stress relief in feline terms.

Understanding this helps owners interpret cat behavior with empathy rather than judgment. Whether your cats groom each other lovingly or occasionally mount out of excitement, it’s all part of their natural social and emotional expression.
