ConclusionsSince hamsters showed stereotypic wire gnawing in cage sizes from 1,800 cm 2 until10,000 cm 2 the welfare of the hamsters even in the very large cages must have beenimpaired. Frequency and duration of wire gnawing significantly decreased withincreasing cage size. Thus, the welfare of pet golden hamsters might be improved byproviding enriched cages of at least 10,000 cm 2 . Further investigations should followon the behaviour and development of stereotypic wire gnawing of golden hamsters indifferently enriched cages.27
