A black cat is lucky or unlucky, depending on where you live.

Cats were sacred to the goddess, Isis in Egyptian mythology.

Bast or Pasht, the daughter of Isis, was represented with the face of a cat. Anyone who killed a cat was put to death.

Archaeologists in Egypt found cat cemeteries from which a shipment of embalmed cats was taken to England. In Egypt it was believed that a black cat crossing one's path brought good luck.

In East Anglia, England, they used to mummify cats and place them in the walls of their homes to ward off evil spirits.

If a black cat walks towards you, it brings good fortune, but if it walks away, it takes the good luck with it.

There are many English, Irish and Welsh tales of fairy cows who gave never-ending milk until their generosity was abused by some greedy human, causing a loss of the cow or her powers. A Lancashire tale tells of a dun cow that appeared during a famine to save the people with her unending milk supply, until one person tried to get more than her fair share by milking the cow through a sieve, leading to the cow's death from exhaustion and sorrow at the trick. Fairy cattle could be dun or red but were more usually white with red ears.

It was once considered unlucky if an offer were made to purchase cattle which were not for sale, leading to their illness and perhaps death. In some districts it was also considered unlucky to strike cattle with human hands; a stick should be used to drive them from place to place, and should be thrown away once the destination was reached. Cattle who stand close together in low ground, and feed hard together, are said to be foretelling rain, but if they stand on high ground the weather will be fair.

Cattle diseases were often attributed to the machinations of fairies, elves or witches, and many charms were used to fend off these magical attacks. Horseshoes or holed stones hung above the door of the byre, or crosses made of rowan wood fixed over cattle-stalls, were believed to ward off evil influences. In the sixteenth century wax from a Paschal Candle would be moulded into a special candle, and wax from it dripped between the ears and horns of the beasts; the remaining wax was then set over the main door, or on the threshold, so that all the cattle had to pass the spot. Written charms were also obtained from local wise-women or cunning-men to ward off evil, and concealed in the roof or under the floorboards.

It was traditional to drive cattle over the embers of the Beltane and Midsummer fires, as a magickal protection against cattle plague and other dieases. As recently as the nineteenth century, some farmers would sacrifice one healthy calf or cow (sometimes burying it under the threshold of the byre with feet pointing upwards) as a symbolic sacrifice that the herd might be spared from cattle plague.
