There is a pretty Agate stone, that has a black line that runs down the middle. Humans say this semiprecious stone, looks like a cats eye. It is said to give the wearer the night vision of a cat, so that humans can see in the dark. Other superstitions for this stone are: that it can give them second sight (Clairvoyance) Or even help them shape-change into the form of a cat. Could you imagine that? Humans are clumsy enough on two feet let alone four!!!
