From Foe to Friend. How Cats Become Their Owners’ Protectors


Cats are often stereotyped as independent, aloof and even cold at times. However, behind their mysterious exterior lies a depth of caring, loyalty and protective instincts. While they may not be as overtly affectionate as dogs, cats form strong bonds with their human families. Given the right circumstances, many cats demonstrate an ability and willingness to defend and protect the people they love. Although they are often seen as aloof, cats can and do protect their owners in certain situations.

Cats Have Strong Bonds with Their Owners

Like dogs, cats can form strong attachments and bonds with their human caregivers. According to a 2019 study by researchers at Oregon State University, the majority of cats are securely attached to their owners and use them as a source of security and comfort 1. This research found that cats exhibit social flexibility with their owners and respond differently when their owner is present versus a stranger. Cats mainly seek out their owner when stressed or afraid.

Cats show affection for their owners through behaviors like head-butting, face rubbing, sitting on laps, vocalizing, and spending time in proximity. A study published in Current Biology found that cats living in loving homes had elevated oxytocin levels, the “love hormone” associated with bonding. This shows that positive interactions with caring owners can influence a cat’s physiology and psychology 2.

While less overtly demonstrative than dogs, most cats do form meaningful connections to their human caregivers over time. With patience and understanding, owners can build close relationships with their feline companions.

Cats Can Detect Medical Emergencies

Cats have a refined sense of smell that allows them to detect subtle changes in scent. There are numerous reports of cats alerting their owners to medical emergencies by exhibiting unusual behavior or vocalizations. According to, cats can detect pheromone changes that indicate illness or seizures in humans. Cats have alerted owners to heart attacks, strokes, migraines, epileptic fits, and other serious medical events.

For example, some cats can sense an impending epileptic seizure up to an hour before it occurs. They may vocalize, pace, or try to get their owner’s attention. There are many accounts of cats alerting others when their owner suffers a medical emergency like a heart attack or stroke. By meowing persistently or running back and forth to the owner, the cat alerts others to check on the situation.

Though the mechanisms aren’t fully proven, many believe cats tune into subtle signs like pheromone changes, abnormal breathing, increased heart rate, or slight behavioral differences. Thanks to their observant nature and close bonds with owners, cats can detect these changes. Their persistent and unusual behavior draws needed attention to rapidly deteriorating medical situations.

Cats Will Defend Against Threats

Cats can be quite protective of their owners when faced with a threat. There are many examples of cats confronting intruders or animals that pose a danger to their owner. According to PetCareRx, cats will often place themselves physically between their owner and the threat as a defensive maneuver1. Their sharp claws and teeth can serve as effective deterrents against unwelcome guests.

Newsweek reported on a viral TikTok video showing a cat aggressively swatting and hissing at a stranger who came too close to the cat’s owner2. The cat continued staring down the stranger until they backed away. This protective behavior demonstrates how some cats will confront perceived threats to keep their owner safe from harm.

While not all cats may react this boldly, those with strong bonds to their owner often see them as part of their family or territory worth defending. Their protective instincts give cats the courage to challenge larger animals or unfamiliar humans if the situation calls for it.

Cats Provide Comfort in Difficult Times

When owners are distressed or crying, cats often comfort them by cuddling up close, purring, and gently patting their face. The soothing presence of a cat can provide immense emotional support during difficult times. There are many examples of cats sensing when their owner is upset and immediately coming over to snuggle into their lap or gently headbutt them. As this Reddit user shared, “Out of all the comments, this got me. My cat was the same; any sign of distress and she was there patting my face and not letting me be alone in my sadness” (source). A cat’s empathy and companionship can be invaluable in times of emotional need.

Research has shown that petting a cat can release oxytocin, a hormone associated with bonding and affection, in both the cat and human. This may explain why petting a purring cat can have therapeutic, stress-relieving effects on owners. A cat’s purr, with its low frequency vibrations, may also play a physically calming role. Whatever the mechanism, it’s clear cats can provide important emotional support and comfort to their distressed owners.

Cats Will Alert Others if Owner is Injured

There are remarkable cases of cats seeking help for their injured or unwell owners. When cats sense that their owner is in distress and unable to call for assistance themselves, some cats have taken action to alert others for help.

In 2021, a cat named Billy raised the alarm when his 83-year-old owner fell 70 feet into a ravine in Cumbria, England and was unable to move. Billy’s strange behavior alerted the owner’s neighbor that something was wrong. The neighbor then discovered the owner injured in the ravine and called for emergency services. Rescuers said that without Billy’s insistence that something wasn’t right, it was unlikely anyone would have found the owner in time (source).

There are many accounts of pets alerting others when their owner is unwell or injured. A pet who senses distress and seeks assistance can be lifesaving for their owner. Cats form close bonds with their families and some cats demonstrate an astounding capacity for getting help when their human is in need.

Cats May Sacrifice Themselves

Some cats have demonstrated an incredible protective instinct by putting themselves in harm’s way for their owners. There are verified reports of cats fighting off vicious dogs, chasing away intruders, and even shielding babies and small children from attack. In one remarkable case, a cat named Scarlett repeatedly attacked a dog that had seized her 5-year-old owner by the leg, until the child was free. The cat sustained serious injuries but survived (PetcarerX). These stories reveal the depths of loyalty and love cats can show when defending their beloved humans.

Scientists theorize this protective response may be rooted in the close social bonds cats often form with their owners over time. It likely goes beyond a basic territorial instinct. There appears to be an actual drive to save their human’s life even at great personal risk. While not all cats may exhibit this degree of selflessness, there are certainly those special few that will brave fire, flood, or fangs to protect the person they have bonded with.

Not All Cats Are Protective

While some cats exhibit protective behavior towards their owners, personality differences mean that not all cats are equally protective. According to a Reddit thread, there is significant variability in cats’ protective instincts ( Some cats are very protective of their owners, while others are more aloof.

An article from PetCareRX notes that a cat’s protectiveness often depends on the cat’s personality and bond with their owner ( Shy, skittish cats are less likely to protect their owners. On the other hand, bold, outgoing cats that have formed a close attachment are more prone to protective behavior. Additionally, some cat breeds like Siamese and Maine Coons are known for loyalty and protectiveness.

In the end, while some cats certainly can and will protect their owners, it is dependent on the individual cat’s personality and relationship with their human. Not all cats exhibit protective behaviors equally.

How to Encourage Protective Behavior

There are some tips that can help strengthen the bond between you and your cat, making it more likely she will act protectively:

  • Spend quality one-on-one time together every day through play, petting, and positive reinforcement training. The more secure your cat feels in your relationship, the more protective she may become.
  • Keep your cat’s routine consistent in terms of feeding, play time, access to favorite spots, etc. Cats feel protective when their environment is stable.
  • Make sure your cat always has access to hiding spots and high perches which allow her to survey her territory. This can increase protective territorial behavior.
  • Introduce new people slowly so your cat doesn’t feel her home is being invaded. Have visitors offer treats and play to form positive associations.
  • Consider adopting a second cat. Bonded cats often act protectively towards each other and their owners.
  • Reward protective behaviors like hissing at strangers and alerting you to sounds with praise and treats. This reinforces those responses.
  • Never punish or scold protective behaviors, even hissing or swatting, as this can prevent future protective responses.

While there are no guarantees with cats, strengthening your bond through consistency, play, and positive reinforcement can encourage protective behaviors in many cats.


In summary, while not all cats may exhibit protective behavior, many cats do form strong bonds with their owners and will take action to defend them in times of distress or danger. Evidence shows cats detecting medical emergencies, fending off threats, providing comfort, alerting others, and even sacrificing themselves for the sake of their beloved human companion. Though cats are often stereotyped as aloof and distant, their capacity for devotion and sacrifice on behalf of their family reveals underlying depths of loyalty, affection, and protectiveness.

By socializing cats from kittenhood and maintaining strong attachments through daily affection and caretaking routines, owners can increase the likelihood of eliciting protective behaviors if needed. However, there are no guarantees, as each cat has its own unique personality and experiences that shape its behavior. Nonetheless, the many accounts of cats safeguarding their keepers provide compelling evidence that – for those cats strongly bonded to their special human – the answer is yes, they often will demonstrate their love by protecting that person in times of distress.
