Gerbil social behavior


Gerbils often have what looks like boxing matches; this is most common amongst young gerbils (gerbil "pups"). These are gentle play fights which usually end in the winner pinning down the loser and grooming it. However, if a pair of gerbils are fighting closely in a ball shape, with both gerbils biting deeply and drawing blood, careful but swift intervention is in order by the pet owner, using a jar or oven mitts to avoid getting bitten.

Gerbils like to sleep in a group, often on top of each other. Sometimes they will absentmindedly groom each other when half asleep. Gerbils have a form of purring called "bruxing" which they do when they are being groomed or while they enjoy being stroked in the hand by their owner.

Squeaks can occasionally be heard from them, and a squeak is usually an indication of annoyance. When another gerbil steps on another without thinking, it will give a squeak, or when a gerbil tries to steal another's food, it will turn with a squeak, and when a male tries to mate an unsuspecting female, she may well turn around sharply to face him and squeak at him. Gerbil pups will squeak more often when very young, sometimes when feeding or if they have strayed from the nest.

Gerbils will raise their hackles and arch their backs to show aggression, often turned to the side and leaning against the other gerbil's body. Usually this is a warning that a fight is about to occur, and if this behavior is observed it is wise to quickly intervene.

Gerbils will also alert each other to danger by thumping on their hind legs, usually triple thumps repeated in a steady sequence. Gerbils will also thump when sexually excited. Younger gerbils are more likely to start thumping than older ones.
