Humane Society Anniversary Day is observed worldwide every November 22 to commemorate the establishment of the Humane Society of the United States in 1954. This day honors one of the largest and most influential animal welfare organizations, which aims to improve the welfare of animals, including companion and farm animals, and wildlife. The Humane Society of the United States emerged from a split within the American Humane Association due to internal disagreements over policies. On this day, individuals are encouraged to support animal welfare through various actions, such as donating to organizations like Humane Society International, volunteering at local shelters, adopting pets, using cruelty-free products, or participating in initiatives like Meatless Mondays. The observance reflects the values of compassion towards animals and highlights the ongoing efforts to combat issues such as factory farming and animal cruelty.
