In the United Kingdom, white cats are considered to be bad luck. This is because a white cat is considered to be the same color as a ghost, so they are considered to be unlucky animals.
There are several superstitions related to white cats around the world. In the United States, white cats seen in dreams or on the road during the day are considered lucky, but to see one on the road at night is considered to be unlucky. An old Buddhist superstition is that light-colored cats bring silver to their owner's home. In Japan, the lucky cat, called maneki neko, is white.
