Hamsters like to chew on the bars of their cage, if they discover a place where they can get out by doing this, they will escape. Perhaps the actual door of it's cage isn't very secure.
Because their a lot smarter then you!
if its a dwarf it can escape unless it's in a glass cage
Hamsters should live in cages that are sealed and closed all the way because they are escape masters. Wire cages are not good for hamsters because they can bite the wire and damage or hurt their teeth. Cages can be found at lots of pets stores. Make sure there are places to burrow because hamsters love to hide when they sleep..
No animals like being in cages.
