Is your hamster gnawing on its cage at all hours of the day and night? It is important to determine the cause of your hamster's behavior before you can correct it. Your hamster may be gnawing on its cage because of boredom, stress, hunger or because it needs exercise. 

Cage gnawing can be a destructive behavior indicating his desire to escape, or it can be a positive behavior if he is trying to relieve stress or have fun. Let's see how to make the right diagnosis.

The need for exercise

Hamsters are very active animals that need space to exercise. If your hamster is confined to a cage that is too small, if it feels cramped, then it may start to gnaw on the bars of its cage in an attempt to escape.

Possible consequences
