Prevention (husbandry & daily care)
Minimize stress during the settling-in period by keeping newly acquired hamsters in a quiet location. Keep the cage and bedding clean and avoid overcrowding. When introducing a new hamster, house it separately for an observation period to prevent potential spread to other animals.
