* The cat may be pregnant and looking for a place to give birth: If you find a pregnant stray, it's important to provide her with a safe, quiet place to give birth.
Folklore and Superstitions:
* Black cats are often associated with good luck: While some cultures associate black cats with bad luck, many believe they are symbols of prosperity and good fortune.
