Your hamster is rolling on his back because he’s feeling scared, trying to get your attention, grooming, regulating his body temperature, marking his scent, or is feeling ill. Suppose you notice this happening alongside other strange behaviors. Don’t hesitate to send your hamster to a veterinarian.

In the rest of this article, I will cover some of the possible causes of your hamster rolling on his back and how you can help your hamster if he exhibits this odd behavior. So let’s get started.

What Does It Mean When My Hamster Rolls on His Back?

There is no shortage of information on the internet and pet owners’ forums about why hamsters often roll on their backs.

However, it is interesting to learn that rolling on the back is one of the body language features researchers have focussed on when investigating hamsters’ body language and behavior.

Your hamster rolls on his back because it’s likely that you’ve startled him while he’s asleep or when he has just woken up. Rolling on the back is a common sign of agitation and aggression in hamsters. Sometimes, hamsters roll on their backs because they’re scared or unwilling to move.

Possible Reasons Your Hamster Is Rolling On His Back

Seeing your hamster rolling on his back when you approach his cage can leave you feeling concerned and wondering what on earth could be wrong with your little furry friend. There are several reasons your small pet might be behaving this way.

Let’s take a look at some reasons your hamster is rolling on his back.

Your Hamster Is Scared

Your hamster might be feeling scared. Unfortunately, hamsters are prey animals. That means your hamster may easily get startled despite your best efforts to make him feel safe.

Suppose you notice your hamster frantically flopping onto his back whenever you approach him, narrowing his eyes, angling his ears backward, and baring his teeth. In that case, it likely means that your hamster probably hasn’t trusted you yet.

Your hamster may be behaving this way to protect himself from possible attacks.

How To Prevent Your Hamster From Feeling Scared

There are a few ways that you can help your tiny hamster if he’s feeling scared and keeps rolling onto his back.

Ways to help build trust with your hamster and keep him calm:

  • Keep your hamster somewhere away from loud sounds. Loud or sudden noises can startle your hamster and cause him to feel on edge. You should do your best to keep your hamster cage in a quiet location where your furry friend will feel safe.
  • Never force your hamster to be held. If your hamster thinks you are forcibly going to hold him each time you enter the room, he may resort to flopping on his back or even biting as a defense mechanism.
  • Give your hamster enough time to get used to your presence. Sit in the room with your hamster or gently touch the outside of his cage. Doing this will help your hamster get used to you and feel less threatened by your approach.
  • Move slowly around your hamster. Never move quickly or suddenly, as doing so will startle your hamster and cause him to panic.
  • Never pick up your hamster from above. When you try to grab your hamster from above and your hand forms a claw, your hamster will panic; hamsters are prey animals, after all. Doing so might result in your hamster biting you or flopping on his back.
  • Don’t let large pets disturb your hamster. Keep your hamster somewhere your cats or dogs don’t have access to. These larger pets will terrify your hamster and could be contributing to your hamster rolling on his back.
  • Offer your hamster a treat when you approach his cage. Offering your little furball a treat is an excellent way to build trust and get your hamster excited to see you.

Ultimately you will want to create a calm, peaceful environment for your furry friend and work on building trust. Doing this is important, especially if you suspect that your hamster is rolling on his back because he’s scared. Of course, it will take time to build trust, but eventually, you should notice progress.

  • Provide good hides for your hamster to cuddle up and sleep in.
  • Keep your hamster away from windows if you live in a colder state such as Alaska.
  • Keep the fan off in your hamster’s room so that cold air doesn’t blow on him.
  • Keep your hamster’s cage away from air conditioning vents during the summer.
