On one of his voyages he was invited by the ruler of a far-off country to dine at his palace. On arriving he found the place so overrun with rats that they even invaded the dining table during meals. The next evening the boy returned to the castle with a cat under his coat and when the rats gathered around the table he let it loose among them. The King was so pleased that he offered a hogshead of gold for the cat. After an absence of ten years the young man returned to Kintail and his ship anchored at Totaig. The sight of such a royal vessel caused considerable stir in the district and all wondered who the richly dressed young man might be. Arriving at his father's door, no-one recognised him and he was received with great hospitality. His father set him at the table and waited upon the young stranger himself, thereby fulfilling the prophesy of the birds. His son revealed who he was, proving his identity by a birth mark on his shoulder and the father was reconciled with the boy whom he acknowledged as his heir.
His son's abilities and knowledge of the world brought him into the favour of Alexander II who commissioned him to build Eilean Donan Castle and protect his subjects against the Norwegians.
