Why Is My Hamster Biting the Bars of Its Cage?

Hamsters are born with a natural instinct to chew. Although biting does serve a purpose, keeping constantly growing teeth trimmed, excessive chewing can indicate that something is wrong. A hamster that is biting the bars of its cage may simply need more attention.

  1. Considerations

    • Boredom is the most common reason a hamster bites the bars of its cage. Most hamsters enjoy interacting with their owner, and biting the cage may mean they want to be handled.

    Warning

    • Biting on metal or plastic bars can result in chipped teeth or even brain damage, according to the hamster care website Hamsterific.com.

    Prevention/Solution

    • A plethora of wooden chew toys specifically designed for hamsters are sold at pet stores to satisfy the need to chew. Tree twigs, sticks and dog biscuits are also safe alternatives.

    Effects

    • If all attempts to stem the biting fail, the hamster may have to be moved into a glass aquarium to prevent injury and to stop the habit.

    Fun Fact

    • According to Hamster-Care.com, hamsters are one of the few animals species born with a full set of teeth that grow continuously throughout their lifetime.
