I was going to say yes to both questions, then again, we used to have a lovely goat in UK, whose only fault was climbing the fences to eat neighbour's prized flowers. She kept the hedges trimmed, controlled the chickens by standing in front of their exit so they were stuck in until someone rescued them, controlled the children, (only this time she would stand by the kitchen door to stop them). She also raided the post box and ate the vat return, and try telling the vat man that one.
