Generally citrus fruits are too acidic to be safe to give(not exactly toxic though as they're often incorrectly labelled as),so I wouldn't even use something containing the juice.The only thing sourced from citrus(but not exclusively as it is found in many completely safe vegetables in lower amounts and fruits as well,just never as high as in citrus products)that is hamster safe would be citric acid.
