My hamster keeps running round in circles what is wrong with it?

You probably moved it in a another cage. When I moved mine, it started going crazy while moving here and there inside the cage. I had it for like 3 months and my neighbour's cat ate it in front of my eyes.I hate my life.......

If he continues on running in circles obsessively, then it might be hamster circling disorder. Either that or you didn't provide a wheel for him to use? Anyways, the disorder. It is actually a recessive trait in hamsters. The hamster that have this trait likes to run in circles, it looks a bit similar a dog chasing its tail. It is advised not to breed that hamster as he/she could pass it down to the babies. If you keep this hamster together with another hamster, its best to separate them as him running in circles will provoke the other hamster and they might fight. If it's not the disorder, nor the wheel problem, then it might be a ear infection. You will have to consult a vet if it is.

She could be completely bored and a bit hyperactive, or could have an actual problem, which is likely if you got her at a petstore. If it continues, try changing the bedding, and if she keeps running around in circles, take her to the vet. Good luck.

I had a dwarf hamster and it did the same thing.

Found out it had been fighting with the other hamster.

If you have another hamster in the cage, this may be why. It might of got hurt by the other hamster.

Either that or its confused.

Take it to the vets.

no i dont think so maybe its playing but you should take professional advice cause it may have a kind of pain but i think hes just playing because rodents just like to run around

Running in circles either means the hamster has had a stroke or has an ear infection, whichever it is please take her/him to the vet.

the senses on one side of body might not be working, maybe it bumbed it's head on something - take her to the vet

it could be just boredom and lack of exercise. get your hamster out more and see if it continues :) something has obviously triggered it. maybe; it's just more energetic and wants to get out more and things. maybe they ate something different?

Take it out and let it run around. It's probably going crazy locked up.

mmm.. maybe it has gone a bit funny in the head... i am not kidding... i got a dog that is very old and she is confused all the time. and old people go bit funny when they are fraul and old. so maybe it is its age.

hope that answered your question.
