Is there anything natural I can put in their cage that they can scratch or anything to help keep their nails short?
My sister who has two piggies has gone travelling and left them with me. Can otherwise care for them fine, but CANT cut nails- they squeal so much and I feel evil! Will take them to the vets to do it every so often (how often should it be done?!) but if there is a way to prevent them getting too long that would be good!
