Every August 8th, cat lovers worldwide get a dedicated day to celebrate the animal that, by most estimates, shares homes and streets with anywhere from 500 to 600 million of them globally. Unlike a lot of "International Day" observances that quietly fade after a few years, this one's grown steadily since it started, picking up momentum across charities, shelters, and social media.

Who actually started it
International Cat Day was founded in 2002 by the International Fund for Animal Welfare (IFAW), created specifically to draw attention to cat welfare and educate people on responsible care. In 2020, custodianship of the day passed to International Cat Care, a British nonprofit that's been working on feline health and welfare since 1958 — making it one of the longer-running organizations dedicated to cats specifically, as opposed to animal welfare more broadly.
Not just a feel-good day
The day carries real weight behind the cute factor. In the UK alone, an estimated five cats a day suffer abuse, and roughly half of the world's cat population is thought to be unowned — strays and feral cats without consistent care. That's the gap International Cat Day was built to highlight: not just appreciating the cats curled up on people's couches, but pushing for better treatment of the much larger population that doesn't have one.
A day with deep historical roots
Cats' relationship with humans goes back further than almost any other domesticated animal. The earliest recorded reverence for cats traces to Ancient Egypt, where the deity Mafdet was worshipped during the First Dynasty as a protector against snakes and scorpions — making cats sacred rather than just useful. Centuries later, that reputation flipped dramatically in medieval Europe, where cats were widely blamed for spreading the Black Death, leading to mass killings of both stray and house cats across the continent.
Worth knowing
Europe actually has its own separate cat holiday — February 17th, observed mainly in Italy, after a 1990 reader poll run by an Italian magazine called Tuttogatto settled on the date. So depending on where you are, you might find two completely different "cat days" on the calendar.
