National Black Cat Appreciation Day is observed worldwide every August 17 to combat superstitions and celebrate black cats. Founded by Wayne H. Morris in 2011 in memory of his late sister June and her black cat Sibad, the day highlights the special bond between black cats and their owners. Despite their negative reputation in many cultures, where they are often seen as symbols of bad luck, some cultures, such as Japanese and Celtic, associate black cats with good fortune. On this day, black cat owners are encouraged to pamper their pets with toys or treats and share their experiences on social media using the hashtag #NationalBlackCatAppreciationDay. Additionally, it serves as a reminder for those looking to adopt a cat to consider giving a home to a black cat, as they are often less likely to be adopted and more frequently abandoned than cats of other colors.
