World Pet Day is observed worldwide every September 27, celebrating the important role pets play in people's lives and recognizing them as family members. The holiday was initiated by the non-profit organizations PVBLIC Foundation and +SocialGood in collaboration with Klooff, a social media platform for pet lovers. It aims to honor the happiness pets bring to their owners while also addressing issues related to animal abuse. Participants are encouraged to visit the World Pet Day website, take selfies with their pets, and share them online, tagging friends to spread the celebration. Additionally, individuals are invited to donate to organizations like Humane Society International that work to protect domesticated animals from cruelty. Another observance of World Pet Day occurs on November 30, with origins linked to the Russian-language segment of the Internet.
