Hamsters have the ability to be handled but it is important to let the hamster know of your presence before trying to touch them. When handling them they should not be restrain forcefully as it can cause them to be more likely to bite. Chinese hamsters are solitary by nature and should not be kept with other hamsters as this will cause fighting between hamsters.
Some common behavioral problems are aggression between two hamsters housed together. Commonly Chinese hamsters prefer being alone and should not be housed with any other hamsters of any gender or species. When handling hamsters it is important to acclimate the hamster to the human hand other wise they might perceive it as a threat, which can lead to biting. Hamsters that has not been socialized with humans may act defensively. Aggression such as biting is often caused by fear or illness from not holding the hamster properly, mistaken you as food as hamster’s eyesight are very poor, or you have woken up your hamster as they are active in the late evening and at night, being woken up could caused them to become disorientated and stressed.
Hamster would most likely be housed in a cage, in what they would consider their territory. By intruding their cage and becoming a threat this can result in physical force such as biting. Cage cleaning can be very stressful as it is an intrusion of their territory and changing the bedding or nesting material can induce a strong stress response, manifesting either psychologically or physically. Prolonged stress can lead to aggression or lead to diarrhea. Psychological response can lead to an inhibition of the animals instinctive behavior, and causing the hamster to abandon its usual nesting site. When cage cleaning many people remove all of the bedding, nesting material, or food stored, but this is wrong as it can lead to a strong stress response as it is a disruption of their territory.
In interaction with each other, investigation of the facial region provides hamsters with information like sexual identity, species, and individual identity. A more subordinate hamster may display a greater tension in his stance, with more erect ears, and wide open eyes. In addition to posture used for communication they also use audible calls, rapid staccato of teeth clicking together was found to be related to agnostic tension or arousal.
Hamsters most commonly interact with the environment by depositing secretion with flank marking. The hamster wheel arch its back to expose the gland and rub its side against a vertical surface like the walls of its cage.
