Pet food company Edgard & Cooper has created a unique pet calendar with the aim of spreading a bit of joy and giving owners an excuse to celebrate with their animals.

The pet holiday calendar features days of reflection (Chew Toy Remembrance Day), famous milestones (The Terrifying Vacuum Tragedy of 1899, which marked the first vacuum cleaner patent) and of course, religious celebrations (St. Bernard’s Day, the holiest day of the year).

And with millions of pets not knowing their exact date of birth – which makes organising birthday parties difficult – the pets of the world decided every 15 September should be a Celebration of the Unknown Birthday. 

“I always assumed there were things my dog Cooper wasn’t telling me,” said Louis Chalabi, co-founder of Belgian-based Edgard & Cooper. “I just didn’t realise how many secrets he held.

“There’s Small Stick Appreciation Day in November, and April is the social highlight of the dog calendar, with The Ball Ball. “The planning has already started for 2026,” says Chalabi. 

And unlike the human calendar, which starts in January, the pet calendar begins in March on the first day of spring. “The cats call it equinox,” informed Chalabi.

The new year is marked with Fishmas, a day that all cats eat fish. To make the day extra special, cats are supposed to refrain from eating fish on Fishmas Eve.

While the pet holiday calendar isn’t for humans, knowing the holidays gives people more reasons to celebrate with their pets. “Co-Dependence Day is on 1 July,” Chalabi pointed out. “Next year, Cooper’s insisting we wear matching shirts.”

Edgard & Cooper is calling on independent retailers to mark special moments with owners with the aid of the complete pet holiday calendar, which can be found and downloaded here: pet-holiday-calendar.com
