Hamster Sleeping Under Water Bottle – Is It OK?

In a cage filled with wood chips and a running wheel, a peculiar sight can catch anyone’s attention – a little hamster sound asleep under its water bottle. This tiny creature, often associated with high-energy and constant activity, seems to be peacefully indulging in a snooze right beside its primary source of hydration.

While this behavior may seem odd to some, it’s not uncommon for hamsters to seek shelter and comfort in their surroundings, even if it means cozying up against a water bottle. In this article, we will explore the reasons behind this behavior and shed light on the fascinating world of hamster sleeping habits.

Why Hamsters Sleep Under Water Bottles

Have you ever noticed your hamster taking a nap under their water bottle? You might wonder why they choose to snooze in such an unusual spot. Here are a few reasons why hamsters sleep under water bottles:

  • Comfort – Hamsters love to burrow and create cozy sleeping areas. The space beneath a water bottle can provide a dark and snug spot for your furry friend to catch some Z’s.
  • Temperature – Hamsters are sensitive to temperature changes and prefer to sleep in a cool, shaded environment. By sleeping under a water bottle, they can benefit from the cooler temperature of the water and stay comfortable.
  • Protection – In the wild, hamsters live in burrows to protect themselves from predators. Sleeping under a water bottle can mimic this natural behavior, helping hamsters feel secure and protected.
  • Hydration – Hamsters need access to water at all times. By sleeping under a water bottle, they can easily reach it when they wake up, helping to prevent dehydration during their active periods.

So, the next time you catch your hamster napping under their water bottle, remember that it’s not just a random spot they chose. It’s their way of staying comfortable, safe, and hydrated.

Choosing The Right Water Bottle For Your Hamster

As a responsible pet owner, it’s essential to provide your hamster with clean and fresh water at all times. And what better way to do so than with a water bottle. But with so many options available, how do you choose the right one for your furry friend? Here are some things to consider:


  • The size of the water bottle should be appropriate for your hamster – not too big, not too small. A good rule of thumb is to get a bottle that can hold at least 120 ml of water.
  • If your hamster is a heavy drinker or if you have more than one hamster, consider getting a larger bottle.


  • Choose a bottle made of sturdy and durable material, such as glass or plastic. Both have their pros and cons, so choose based on what you feel is best for your pet.
  • Make sure the material is non-toxic and safe for your hamster to drink from.


  • The spout should be small enough for your hamster to drink from without getting its head stuck.
  • Make sure the spout is made of a material that won’t rust or corrode over time.

Ease Of Use

  • Choose a water bottle that is easy to fill and clean. Bottles with wide openings or detachable parts are generally easier to use and clean.
  • Make sure the bottle is easy to attach to your hamster’s cage and won’t fall off easily.


  • Choose a water bottle that is leak-proof to prevent water from spilling onto your hamster’s bedding or cage.
  • Test the bottle before using it with your hamster to ensure it is indeed leak-proof.

When choosing a water bottle for your hamster, consider the size, material, spout, ease of use, and leak-proofness. By selecting a suitable water bottle, you will ensure that your hamster remains hydrated, healthy, and happy.

Signs Of A Dehydrated Hamster

As a responsible pet owner, it is crucial to keep track of your hamster’s water intake. Dehydration can lead to serious health issues and even death in small animals like hamsters.

Here are some signs to look out for that indicate your hamster may be dehydrated:

  • Dry or sticky mouth
  • Sunken eyes
  • Lethargy or lack of energy
  • Loss of appetite
  • Reduced urine output
  • Dry, flaky skin

What can you do to prevent dehydration in your furry friend?

  • Always make sure fresh water is available and easily accessible.
  • Provide a water bottle and check daily that it is working correctly.
  • Add fruits and vegetables to your hamster’s diet, as these contain water and can help keep them hydrated.
  • Avoid placing the hamster’s cage in direct sunlight, as this can cause excessive heat and dehydration.

Remember, prevention is always better than a cure. Keep an eye out for the signs of dehydration and take action immediately if you suspect your hamster is not drinking enough water.

Alternatives To Sleeping Under A Water Bottle

While hamsters love sleeping under water bottles, it’s not always the best option. If your furry friend seems uncomfortable or stressed, there are several alternatives you can try.

  • Provide your hamster with plenty of bedding and nesting material. They can burrow and create a cozy space to sleep.
  • Some hamsters enjoy sleeping in hammocks or hanging pouches. This provides a unique and comfortable sleeping experience.
  • Offer your hamster a small enclosed space, such as a cardboard box with the sides cut out. This can provide a sense of security while sleeping.
  • If your hamster’s cage has multiple levels, provide sleeping options on each level. This can help distribute weight and prevent soreness.
  • Providing a soft fleece blanket or pad to sleep on can add an extra layer of comfort.

Remember, each hamster is unique, and what works for one may not work for another. Pay close attention to your hamster’s behavior and make adjustments accordingly.

How To Train Your Hamster To Sleep Elsewhere

Do you find your hamster always sleeping under its water bottle? Although it might look cute, it’s not the safest place for your tiny friend to catch some Zzz. But how do you train your hamster to sleep elsewhere?

Here are some tips:

  • Provide a cozy and comfortable sleeping area. A hamster house with a soft bedding can make a great and safe sleeping place for your pet. You can also add some shredded paper or tissue for extra warmth and comfort.
  • Relocate the water bottle. If your hamster associates sleeping with the water bottle location, it might be time to move it somewhere else. Try placing it on the opposite side of the cage or attaching it to the top of the cage instead of the side.
  • Offer alternative hiding spots. Hamsters are natural burrowers, so they love to hide and feel secure. Providing a few options, such as a cardboard tube or a small box, can encourage your hamster to explore and find a new favorite sleeping spot.
  • Use positive reinforcement. Whenever you see your hamster sleeping in its new spot, praise it with a gentle voice or a treat. This will help the hamster associate the new sleeping spot with positive experiences.
  • Be patient. Rome wasn’t built in a day, and your hamster might take some time to adjust to its new sleeping arrangements. Keep trying and experimenting with different options until you find one that works for both you and your furry friend.

By training your hamster to sleep elsewhere, you can ensure that it has a safe and comfortable sleeping spot. With a little patience and creativity, your hamster can enjoy its slumber without the risk of getting squished under a water bottle.

Other Hamster Sleeping Habits

Just like humans, hamsters have their own unique sleeping habits that may surprise owners who are new to caring for these small pets. Here are some interesting sleeping habits to look out for:

  • Nest builders: Hamsters are natural nest builders and will create cozy sleeping areas where they feel secure. They tend to burrow deep into their nesting material and may even sleep in piles of shredded paper or grass.
  • Daytime nappers: While hamsters are predominantly nocturnal, they do take short naps during the day to conserve energy. These naps typically last anywhere from five to twenty minutes and may happen in different locations throughout their enclosure.
  • Barrel rollers: Some hamsters may roll onto their backs and nestle themselves into a tight ball before falling asleep. This position allows them to feel protected and safe while they rest.
  • Bedtime snackers: Hamsters have a high metabolism, which means they may need to snack before bedtime to keep their energy levels up. Owners may notice their hamsters taking several trips to their food bowl before settling down for the night.
  • Spooning buddies: If you have more than one hamster, you may notice them sleeping in pairs, cuddling up to one another for warmth and security. Hamsters are social animals and enjoy sleeping with their friends.

Knowing your hamster’s sleeping habits can help you to provide the best possible care for them. It’s important to create a comfortable and safe sleeping environment where they can snuggle up and get some rest. With proper care, your hamster will be a happy and healthy companion for years to come.


In conclusion, the sight of a hamster sleeping under a water bottle may seem amusing, but it is also an indication of a serious issue that needs to be addressed. Hamsters require a comfortable and safe living space to live a healthy life. The fact that they are willing to sleep in uncomfortable positions to avoid a poorly designed enclosure is a warning sign for pet owners.

As pet owners, we have a responsibility to ensure that our animals live in an environment that promotes their well-being. We need to consider the size of the enclosure, the quality of the bedding, the availability of food and water, and the opportunities for exercise and play.

In the case of a hamster sleeping under a water bottle, it may be necessary to reposition the bottle, provide a more spacious enclosure, or invest in a better water system. By taking these steps, we can promote the well-being of our pets and ensure that they live a fulfilling and happy life.
