Hamster and Gerbil Behavior 

Hamsters and gerbils both love to chew on everything. Provide hay, a wood block or an empty toilet paper roll to satisfy this natural behavior. Both hamsters and gerbils commonly hide food throughout their cages.  

While hamsters and gerbils are similar, they have some specific behavioral differences: 

  • Nocturnal, should be gently handled if picked up while sleeping
  • Single animals do fine and can be kept in pairs depending on the breed and sex
  • Active, fast, and rarely bite when correctly handled
  • Social animals and do well in pairs
