Why Does My Cat Cuddle My Arm While Sleeping?

Why Does My Cat Snuggle Up To Me While Sleeping?

If you’ve ever woken up in the middle of the night with your cat snuggled up against you, their paws hugging your arm, you’re not alone. This adorable sleeping position is common for many cats and their owners. But why do cats like to sleep so close to us?

Cats can sleep up to 20 hours a day, so they take their sleeping habits seriously. Their choice of sleeping positions and locations provides insight into their comfort, security, and bonding with their humans. Keep reading to discover the top reasons your cat loves to cozy up to you at bedtime and tips for enhancing the snuggling.

Reason 1: Comfort

Cats often cuddle with their owners’ arms while sleeping as a source of comfort and security. Cats tend to form strong bonds with their owners and see them as a safe haven in times of stress or uncertainty. An owner’s arm provides a warm, soft surface for the cat to rest against and the cat feels protected being so close to their trusted human companion. According to cats.com, cats “see their owners as a source of comfort and security” so they seek physical closeness while resting (Source). By hugging an owner’s arm, a cat feels relaxed and reassured, allowing for a deeper and more restful sleep.

Reason 2: Warmth

Cats love warmth and will often hug their human’s arms or bodies while sleeping in order to stay warm. A cat’s normal body temperature ranges from 101°F to 102.5°F, which is several degrees warmer than the human body temperature of around 98.6°F (1). By cuddling up close to their human’s warm body, a cat can maintain a cozy temperature while sleeping.

Cats tend to become very relaxed and sleepy when they are warm and comfortable. By hugging an arm or pressing their bodies against a human while sleeping, cats can soak up the warmth radiating from the human body. This allows them to get to that sweet spot of warmth that they find perfect for sleeping. The fact that cats purr when content also indicates they are likely feeling a soothing warmth from the cuddle (2).

In addition, cats have a tendency to sleep for long periods of time, upwards of 16 hours a day on average. By cozying up to a human for warmth, they can maintain a comfortable body temperature throughout these long sleep sessions without having to frequently readjust their position.

So in summary, cats are drawn to the warmth from their human’s body while sleeping as a way to stay comfortably heated for long naps and cat naps.

Reason 3: Scent

Cats have scent glands located on their cheeks and head that release pheromones, allowing them to mark objects and other cats with their scent (source). When your cat head butts or rubs their head against you, they are transferring their scent onto you as a form of marking and claiming you as their own. This scent exchange establishes bonds and relationships between cats and their owners. It’s your cat’s way of saying “you belong to me!”

Reason 4: Kneading

One of the most common behaviors cats exhibit while cuddling with their owners is kneading or making “biscuits” with their paws. This rhythmic flexing and relaxing of the paws often accompanies purring during feline cuddles. Kneading releases feel-good hormones like endorphins and oxytocin in cats, which makes them feel relaxed and bonded with their human companion (Source). The motion and pressure of kneading also helps cats ease tension and sink into a calm, meditative state. By kneading on their human’s body, cats are essentially massaging themselves to sleep while also showing affection. The act of kneading on a particular person or blanket also allows cats to spread their scent and mark their preferred cuddle buddies.

Reason 5: Bonding

Cats form close social bonds with their owners similar to the bonds dogs form. Cuddling releases oxytocin, also known as the “love hormone,” which reinforces feelings of trust and attachment between a cat and its owner (Source). When a cat snuggles up to sleep with its owner, it is expressing its bond and showing affection in its own way.

Cats initially bond with their owners during kittenhood as they rely on them for food, shelter, and care. This attachment grows over time through daily routines and positive interactions like petting, brushing, and playtime. Sleeping curled up against or on top of an owner continues strengthening the bond by releasing oxytocin and providing comfort through contact.

For cats adopted as adults, it may take longer to form an attachment, but bonding is still possible through patience and care. An adopted cat hugging and sleeping with an owner is a sign that a strong bond has developed (Source). Cuddling during sleep is a cat’s unique way of demonstrating affection and trust in its chosen human.

Reason 6: Protection

Cats have a strong instinct to protect their territory and their family. When a cat sleeps curled up against or on top of their owner, they are watching over them and showing protective behaviors. The cat considers its owner to be part of its family group and sees them as a source of safety and protection. Some signs of this include a cat guarding its owner when strangers approach, swatting at or hissing at potential threats, and patrolling the home at night while the owner sleeps.

According to an article on Hill’s Pet Nutrition website, “Cats are often stereotyped as standoffish and aloof, even to the people who love them most, but the truth is that cats can be just as protective of their people as dogs can be.” https://www.hillspet.com/cat-care/behavior-appearance/are-cats-protective-of-humans

On Reddit, many cat owners share stories of their cats guarding them at night or reacting to perceived threats. One commenter said “So yes, I think he understands that you were protecting him” when referring to protecting their cat from an aggressive dog. https://www.reddit.com/r/CatAdvice/comments/k3n912/do_cats_understand_their_owners_protecting_them/

Reason 7: Routine

Cats thrive on regular routines and find comfort in predictability. According to The Ultimate Guide to Sleeping with Your Cat, many cats have a set bedtime routine that includes cuddling up with their owner in bed. This nightly ritual provides cats with a sense of reassurance and consistency. Just like humans, cats can become stressed when their normal schedule is disrupted. Therefore, allowing your cat to sleep with you every night allows them to maintain their habitual sleeping and cuddling routine, which reduces anxiety and promotes better sleep.

Tips for Better Cuddling

One of the best tips for encouraging more cuddling from your cat is to let them initiate contact on their own terms. Cats prefer to approach for snuggles when they feel safe and comfortable, rather than being forced into physical contact. Here are some suggestions:

  • Sit or lie down in an inviting position, such as reclining on the couch or bed. Wait for your cat to jump up and make themselves comfortable against you.
  • Pet your cat gently while they are nearby, but don’t pull or pick them up. Allow them to rub against your hand and initiate further snuggling if desired.
  • Use treats to positively reinforce when your cat seeks physical affection. But don’t overly bribe with treats, as this can reduce the sincerity of the bonding.
  • Establish a soothing bedtime routine with calming pets and soft brushing. Be patient as your cat learns to associate this with relaxation.
  • Talk to your cat in a calm, tender voice and blink slowly when making eye contact. These act as social cues to help a shy cat feel safe to approach.

While cats can be independent at times, respecting their preferences and not forcing cuddles goes a long way in nurturing a lasting snuggle bond between cat and human.


In summary, there are many reasons why cats will hug their owners’ arms while sleeping. Cats hug arms for comfort, warmth, scent, kneading instinct, bonding, protection, and routine. Cats are social creatures that bond closely with their owners, so arm-hugging behaviors reinforce that connection. While some cats just find arms a convenient place to snooze, many see them as a source of comfort and affection. By understanding why your cat wants to snuggle up to your arm, you can provide a better sleeping environment and strengthen your relationship.
