Why Is My Hamster Running in Circles in Its Cage?

Every hamster has a distinct personality, and observant owners will quickly notice recurring behavior. But, if a hamster starts acting oddly, like running in circles, it could indicate an illness, and veterinary care should be sought immediately.

  1. Stroke

    • A hamster that is seen running in circles with a bit of a head tilt has most likely suffered a stroke, according to the Hamster Club.

    Ear Problems

    • Any disturbance to the ear canal, whether it be an inner ear infection, tumor or ear mites, can throw off a hamster's equilibrium, which may cause it to run in circles.

    Boredom

    • Hamsters are active animals that need sufficient space to burn energy. A hamster kept in cramped quarters may become bored, and end up running in circles.

    Neurological Disorder

    • According to HamsterBungalow.com, some hamsters are born with neurological or genetic disorders that will cause them to run in circles their entire lives. This can sometimes be kept under control with medication.

    Fun Fact

    • Hamsters enjoy running in circles in exercise wheels for hours. These wheels are available as free standing units or ones that attach to the side of most habitats.
