Understanding animals through their behaviour


Hamsters may look sweet but they respond violently to all intruders. ‘If you put two hamsters together, they will fight each other and one usually kills the other,’ said the late Pamela Milward of the Southern Hamster Club. If a baby hamster gets into the cage of a strange adult, the adult will kill it. So they would certainly kill a mouse.’

Worse still, after murdering an intruder, they will often turn cannibal. They usually eat the brains. You will often find the body with the head eaten. In colonies of Chinese and Russian hamsters, who do live together, they will eat the head off if one of them dies a natural death.
