Understanding Your Hamster: 12 Strange But Common Behaviors
Hamsters are fascinating creatures with unique personalities and peculiar habits that can sometimes puzzle even experienced pet owners. While some of their behaviors might seem unusual or even concerning at first glance, most are completely normal and natural for these small rodents. Understanding these common behaviors is essential for providing proper care and ensuring your hamster remains healthy and happy. In this comprehensive guide, we’ll explore twelve strange but entirely common hamster behaviors and explain what they mean.
1. Sniffing Things Out
When you first bring a hamster home, one of the most noticeable behaviors you’ll observe is constant sniffing. Your hamster will wiggle his little nose almost continuously as he explores his new environment. This behavior makes perfect sense when you understand hamster sensory capabilities. Hamsters don’t have great eyesight, but what they lack in visual acuity, they compensate for with an exceptionally keen sense of smell. Their nose is their primary tool for navigating the world and gathering information about their surroundings.
Sniffing is often accompanied by standing up on hind legs, which your hamster might do to investigate things further or to better catch any nearby perceived threats. Your hamster may also assume this standing position if he catches a whiff of a tasty treat. This behavior is completely natural and indicates your hamster is actively engaged with his environment and gathering important sensory information.
2. Exploring
Hamsters are naturally curious creatures driven by an innate need to explore their surroundings. When placed in a new enclosure or introduced to new toys and accessories, your hamster will spend considerable time investigating every corner, crevice, and object. This exploratory behavior serves multiple purposes: it helps your hamster map out his territory, identify potential food sources, and locate safe hiding spots. Providing various objects and structures for your hamster to explore promotes mental stimulation and prevents boredom, which is crucial for their overall well-being.
3. Stuffing Those Cheeks
One of the most endearing and amusing hamster behaviors is cheek stuffing. If you see your hamster’s cheeks suddenly bulging to the brim, don’t be alarmed—it’s not a case of hamster mumps. Like squirrels, hamsters are natural food hoarders. They possess specialized cheek pouches that can expand dramatically, sometimes doubling the size of their head. Hamsters can carry up to 50% of their body weight in their cheeks, which is an impressive feat for such small animals.
Your hamster stuffs food into these pouches so he can move large quantities back to his special, self-designated hiding spots located in tunnels hidden throughout his bedding or other areas of his enclosure. This hoarding instinct is deeply ingrained in hamster biology—in the wild, storing food ensures survival during scarce periods. After stuffing their cheek pouches with food, hamsters will take it back to their burrow or special hiding place and empty the pouches into their food stores. This behavior is perfectly normal and shouldn’t cause concern.
4. Busy Burrowing
You’ll often see a lot of wiggling happening underneath your hamster’s bedding material. This is your little furball burrowing to create covered areas where he can retreat to rest or hide his extra stashes of hamster food. Burrowing is a deeply natural behavior for hamsters, reflecting their wild instincts to create underground tunnels for shelter and food storage. Burrowing provides your hamster with a sense of security and fulfills his psychological need for a safe space.
Expect to see increased burrowing activity after you change your hamster’s bedding material, as he has to start creating his tunnel system all over again. Providing adequate bedding depth—at least 2-3 inches—allows your hamster to engage in this natural behavior comfortably. This activity keeps your hamster mentally stimulated and physically active, contributing to overall health and happiness.
5. Making Himself Disappear
You might find yourself wondering where your hamster has gone. Hamsters like hideouts and will frequently disappear into spots in their bedding, hamster-size igloos, or areas burrowed under hamster toys. This behavior can be puzzling to new hamster owners, but it’s perfectly normal and even healthy. It’s important to allow your hamster privacy and access to hiding spots. Hamsters are prey animals, and keeping out of sight is their best defense mechanism in the wild. Even though your hamster is safe in captivity, these instincts remain strong.
Providing multiple hiding spots throughout the enclosure gives your hamster options and reduces stress. When your hamster chooses to hide, he’s engaging in a crucial survival behavior that makes him feel secure and protected. Resist the urge to constantly disturb your hamster in his hideouts; instead, respect his need for solitude and observe from a distance.
6. Pulling An All-Nighter
Don’t expect your hamster to go to bed when you turn out the lights at night. Hamsters are nocturnal creatures and can be little busybodies during nighttime hours. If you find yourself unable to sleep because of the sound of your hamster working out on his exercise wheel or rustling around his cage, you might want to consider moving the cage to a different room. This nocturnal nature is fundamental to hamster biology; they’re naturally most active during the dark hours and sleep during the day.
Understanding this behavioral pattern is important for setting realistic expectations about your hamster’s activity schedule. Rather than fighting against this natural rhythm, work with it by providing appropriate nighttime enrichment and considering the cage location relative to your sleeping area.
7. Sleeping While You’re Awake
If you hadn’t noticed that your hamster is most active at night, you might be bewildered by why your little hammy sleeps all day. Don’t worry—your hamster is not unwell. He’s simply on a different sleep schedule than you are. Hamsters typically sleep 14-16 hours per day, with most of that sleep occurring during daylight hours. This daytime lethargy is completely normal and part of their nocturnal nature.
Temperature also affects hamster sleep patterns. If your home drops below 60 degrees Fahrenheit, don’t be surprised if your hamster undergoes a mini hibernation and sleeps longer than usual. During colder months or in cool environments, hamsters may enter a state of torpor to conserve energy. This is a natural survival mechanism, but you should ensure your hamster’s environment stays above 65 degrees Fahrenheit for optimal health.
8. Chewing Like Crazy
A hamster’s teeth continuously grow throughout his entire life, which means your pet will constantly seek out items to chew in order to keep his teeth properly maintained and worn down. Without adequate chewing opportunities, hamster teeth can become overgrown, leading to serious health problems. This is why providing appropriate chewing items is essential for your hamster’s well-being.
Give your hamster safe items to chew, such as untreated wood blocks, hay, or specially designed chew toys. You’ll enjoy watching him hold these items in his little hands as he chomps away. Wood chews in particular help naturally wear down teeth and maintain proper dental health. Observing your hamster’s chewing behavior is also a good way to monitor his overall health; if you notice he’s not chewing regularly or if his teeth appear overgrown, consult your veterinarian immediately.
9. Leaving A Mark
You might notice your hamster hitting his flanks (hips) against things in his enclosure or even against your hands. He’s not uncoordinated; he’s claiming the item or spot as his own through scent marking. Hamsters have scent glands, but their exact location varies depending on the species. Syrian hamsters have a scent gland on each hip, while dwarf hamsters have a single scent gland on their underside, just below where you would imagine their belly button to be.
This scent marking behavior is how hamsters communicate with other hamsters and establish territory. By rubbing his scent glands on objects, your hamster is essentially saying “this is mine.” This behavior is completely normal and healthy, and it’s actually a good sign that your hamster feels comfortable and secure enough in his environment to engage in territorial marking.
10. Squeaking Or Hissing
A hamster making audible noises is generally not a happy hamster. If you hear your hamster squeaking or hissing, it’s important to understand what he’s communicating. An annoyed or frightened hamster might squeak or resort to hissing to get his point across that he’s quite angry and wants to be left alone. These vocalizations are warning signals indicating your hamster is stressed or feels threatened.
If you hear these sounds, give your hamster space and try to identify what’s causing his distress. Common triggers include loud noises, rough handling, or perceived threats from other pets. By respecting these warning signals, you can prevent bites and help your hamster feel more secure. However, occasional soft teeth chattering, particularly when eating favorite foods or grooming, typically indicates happiness rather than aggression.
11. Laying Back
Some hamsters prefer to lie on their backs when sleeping or just to relax. This behavior might seem odd at first, but many hamsters enjoy this resting position. If your hamster chooses to sleep or lounge on his back, let him chill out in his favored pose. This behavior is a sign that your hamster feels safe and comfortable in his environment—only truly relaxed hamsters will assume this vulnerable sleeping position.
It’s important not to disturb your hamster while he’s in this position. Wait until he’s back up on his feet before attempting to pick him up or handle him. Respecting your hamster’s rest time and preferred sleeping positions contributes to a calm, well-adjusted pet.
12. Grooming
You’ll see your hamster groom himself on a daily basis through licking, scratching, and cleaning his fur. This is a sign that your hamster is healthy and happy, and actively maintaining his coat in good condition. Grooming serves multiple purposes: it keeps the fur clean, helps regulate body temperature, and is a natural stress-relieving activity. Hamsters may groom more frequently when they’re anxious or stressed, so paying attention to grooming frequency can help you gauge your hamster’s emotional state.
Occasionally, you might notice your hamster grooming another hamster if you have multiple hamsters in the same enclosure. This behavior, called allogrooming, is a sign of affection and social bonding. However, it’s important to note that many hamster species, particularly Syrians, are solitary and should not be housed together.
Creating The Ideal Environment For Natural Behaviors
Understanding and accommodating these natural hamster behaviors is essential for responsible pet ownership. Provide a spacious enclosure with ample bedding for burrowing, various hiding spots for security, appropriate toys and chew items, and an exercise wheel for nightly activity. Respect your hamster’s nocturnal schedule, and avoid disturbing him during his daytime rest period. By supporting these natural behaviors, you’ll help ensure your hamster lives a healthy, enriched, and fulfilling life in captivity.
