Our tortoises are fed a variety of vegetables, including kang kong, sweet potato leaves, celery, cucumber and turnip. With welfare and enrichment in mind, keepers whip up vegetarian ‘kebabs’ by stringing some veggies together and tying them up just above reach. These tempting treats ‘stretch’ their chelonian charges physically and mentally by developing problem-solving skills and encouraging the display of natural behaviour, like reaching for vegetation at higher ground.
