Two that spring to mind are St. Ceiran of Clonmacnoise who had a dun cow and St. Kevin of Glendalough who had a white.
Both of these produced enormous quantities of milk. I don't know about Ceiran's cow, but Kevin's never at grass. Each morning it would leave its field and wander off. It was followed one day and it was discovered that every morning the cow would go and lick Kevin's feet while he slept.
There are other milk links at Glendalough. There is the Deer Stone, a bullaun, that has a cutesie story. The king's baby had no milk to feed upon, so Kevin prayed and every day a deer would come from the woods and fill the bullaun with milk for the child. The deer was killed by a wolf and when Kevin gave it a good talking to the wolf gave the milk instead. The monastic settlement got its boundaries by communication with animals too. The local king said Kevin could have as much land as a the king's very old and crippled pet goose could fly around. Kevin touched the goose and it became young and flew again. Kevin also banished larks from the glen - although they live in the mountains around there today you will never hear one in the valley. He commanded a willow to sprout apples so that a boy could be cured by eating one - no apple trees existed in the Glen.
There are other animal stories connected with him too. An otter supplied the monastery with salmon when there was a famine. One day he was praying and a blackbird landed on his outstretched hand and laid an egg. Kevin stood there until the egg hatched.
He was also a master of herbs.
He was born at The Fort of the White Fountain.
<b>HE WAS A FECKIN' DRUID!</b>
