Why Do Hamsters Always Try To Escape?

(Last Updated On: May 28, 2022)

Hamsters are mini escape artists. If you don’t secure their cage, they can slip through gaps and run amok in the environment beyond. Finding them and getting them back can be difficult.

Hamsters will attempt to escape if they feel unsafe or the opportunity arises. Stress due to boredom, a lack of hiding spaces, or a too-small cage can lead to escape attempts.

Hamsters have strong burrowing instincts so, if you don’t provide at least 8 inches of bedding, they’ll climb up their cage to get out.

Most hamsters always want to escape, even if their setup meets all of their care standards. Female Syrian hamsters are the main culprits and are much harder to please than males.

Why Does My New Hamster Keep Trying To Escape?

It can be stressful to find your hamster desperately trying to escape its cage. As mentioned, no matter how well you set up your hamster’s enclosure, some are naturally inclined to find their way out.

Female Syrians are most likely to do this, as they’re more destructive and temperamental. Males tend to be calmer and less territorial. That being said, all hamsters are at risk of escaping if they get the chance, particularly when they’re unfamiliar with their surroundings.

There are several reasons why your new hamster keeps trying to escape, such as:

Cage Too Small

Hamster cages need to be a particular size for hamsters to be happy.

The recommended sizes are as follows:

  • The Humane Society of the United States (HSUS): A wire cage measuring 576 square inches or a 24 x 12 inch aquarium measuring 288 square inches.
  • American Society for the Prevention of Cruelty to Animals (ASPCA): 2000 square inches.
  • Royal Society for the Prevention of Cruelty to Animals (RSPCA): As large as possible.

It’s widely accepted within the hamster welfare community that hamster cages should be at least 70 x 40 cm (430 square inches) for dwarf hamsters and 80 x 50 cm (620 square inches) for Syrian hamsters.

However, a bigger enclosure is always preferred to enable hamsters to burrow, forage, and explore.

A study by Animal Welfare studied several golden hamsters in a range of different sized cages. They found that hamsters kept in a cage of 10,000 cm2 were the happiest. If you keep your hamster in a cage that doesn’t meet minimum requirements, it’s more likely to attempt to escape.

Hamsters escape their cages because of their instinct to dig long underground tunnels. Their natural digging instincts are amplified when there’s not enough bedding for them to tunnel through. Wild hamsters dig tunnels reaching approximately 0.7 meters deep, so they require lots of digging space to satisfy their instincts.

Similarly, some hamsters are hardwired to try to escape. As mentioned, female Syrians are harder to please. You may find your hamster has a big cage but still tries to escape.

Unfortunately, even the most enriching cages aren’t always enough to make them happy. As a result, you’ll need to focus on making sure your hamster can’t escape rather than stopping it from getting away.


Hamsters are prey animals, which means they’re constantly on the lookout for dangers. As a result, hamsters are naturally timid animals. If they don’t feel safe within their enclosure, they’ll attempt to get out of it and flee.

Many things can cause stress, such as:

  • Cats and other pets
  • Loud noises
  • Bright lights
  • Frequent handling (if they haven’t been tamed)
  • Not enough bedding
  • Too many full cage cleans

Think about moving your hamster’s cage or creating a quieter, darker environment for your hamster to live in. Don’t let any other animals in your hamster’s room so that it doesn’t feel threatened.


Hamsters are active animals that run for several miles and forage for food in the wild. If they don’t have a large exercise wheel and plenty of boredom breakers for entertainment, they’ll find other means of enrichment. This includes escaping to explore the wider surroundings.

Some of the best forms of enrichment include:

By distracting your hamster with things it enjoys playing with inside the cage, it’ll be less inclined to escape.

Too Much Open Space

Even though hamsters need lots of floor space, they like their enclosures to be semi-cluttered so that they can escape danger. If you don’t provide enough hideouts or places for your hamster to retreat to, it’ll feel threatened enough to attempt to escape its environment.

Because hamsters are prey animals, they’re constantly on high alert. Even the slightest noises can trigger their prey instincts. That’s why they need lots of hiding places to feel comfortable and safe.

Why Is My Hamster Climbing the Cage?

Hamsters are good at climbing and scaling their cages to explore and find out more about their environment. Hamsters in barred enclosures are more likely to climb than those with solid walls. They also monkey bar along the roof. Unfortunately, this can lead to injuries from where the hamster loses its grip and falls.

Cage climbing isn’t always a sign that your hamster wants to run away. It’s just as likely your hamster wants to get out of its cage to explore rather than escape. That being said, hamsters climb their cages for similar reasons to wanting to escape – most predominantly due to stress or a lack of boredom breakers. As a result, this behavior does also signifies an issue.

While hamsters scramble over rocks and birchwood in the wild, they aren’t natural climbers. Enclosures are something hamsters only experience in captivity, so they learn to climb their cages as pets. Climbing commonly indicates that something’s bothering your hamster, such as a predator or insufficient environment.

How Do You Find a Lost Hamster?

If your hamster succeeds in its escape attempt, you’ll need to find a way to get it back. There are many methods you can try to find your pet. Take a strategic approach with the following steps:

Your first step should be to look for your hamster. You might have more luck at night-time when your pet’s more likely to be active. Make sure you:

  • Check underneath and behind furniture
  • Look inside cabinet drawers – even the ones at the top
  • Check underneath blankets and bedding in case your hamster’s made a nest with them
  • Look behind all appliances. You might need to use a torch for better visibility
  • Take a look inside any bags and backpacks
  • Check inside and behind your closet

Lure Your Hamster Out with Treats

If you don’t find your hamster straight away during your search, you’ll need to use treats to lure it out. Be careful, though – you only want to use a couple of treats.

If you use too many, your hamster will stash them in its pouch and store them in its hiding place. This will make it harder for you to locate and retrieve your hamster. Place a couple of treats in each room to determine which one your hamster has escaped to.

Track With Flour

An excellent way to track your hamster’s whereabouts is to spread a light dusting of flour across the floor. Once your hamster walks through it, you can see where it’s been and track its movements, making it easier to locate.

You can also place a layer of aluminum on the floor and wait until your hamster becomes active. You’ll be able to hear as soon as your hamster walks over it and have a chance at catching it as a result.

Create a Bucket Trap

The bucket trap is the best way to catch a lost hamster. To make one, you’ll need:

  • A tall bucket
  • Books or thin boxes
  • Treats, such as peanut butter
  • Cucumber (for water)
  • A clean tea towel

Then you’ll need to follow these steps:

  1. Place the tea towel folded up in the bottom of the bucket. It needs to be thick to break your hamster’s fall.
  2. Put your chosen treat and a slice of cucumber on top of the tea towel.
  3. Stagger the books or boxes next to the bucket to create some steps for your hamster to climb.
  4. Periodically check the bucket. You may need to be patient, but with luck, your hamster will eventually fall in, leaving you the chance to retrieve it.

How Do I Stop My Hamster From Trying To Escape?

It can be stressful to see your hamster trying to escape all the time. Thankfully, there are things you can do to discourage this behavior, such as:

Use a Glass Tank

Barred cages are easier for hamsters to escape than glass tanks and aquariums. Hamsters can’t climb the glass walls, so if you have an escape artist, you should consider upgrading your wire cage to a tank.

That way, your hamster won’t be able to get out. Ensure you provide a mesh lid with ventilation so that your hamster doesn’t overheat, as glass retains more warmth than wire enclosures.

40-gallon breeder tanks from Petco work well. They’re also relatively inexpensive. Fish tanks are another option, but you must make sure they’re not too narrow. Hamsters need more floor space than height, which is why wider breeder tanks work best.

Provide An Exercise Wheel

As mentioned, hamsters can run up to 6 miles a night. If they don’t have the means to be active, they’ll attempt to escape. An exercise wheel is essential in all hamster cages.

Hamsters also need large wheels to prevent spinal injuries. Many owners mistakenly provide wheels that are too small. Eventually, though, hamsters will stop using them because of the discomfort. That’s why experts recommend the following wheel sizes:

Hamster BreedExercise Wheel Size
Dwarf hamsters:20 cm (8 inches) in diameter
Chinese hamsters:26 cm (10 inches) in diameter
Syrian hamsters:28 cm (11 inches) in diameter

If your wheel is too small and your hamster attempts to escape, it’s time to upgrade to a larger one.

Let Your Hamster Roam

Your hamster may be desperate to escape because it wants to get outside and explore. There’s no harm in letting your hamster explore the world beyond its cage, as long as you supervise it at all times.

You can let your hamster free roam by blocking off access to small spaces. If that’s not feasible, then get a large playpen and add some hideouts, a wheel, and other things for your pet to play with. Sometimes, a break from their everyday surroundings is enough to keep hamsters happy.

By optimizing your hamster’s environment, you can minimize its stress, reducing the chances of escape.
