Denmarks version of Halloween is coming up in a few weeks and the kids are working hard decorating their barrels. Today these barrels are filled with candy, fruit, and a black cat decoration on the outside. But back in the days, they were filled with an actual black cat. The kids, and probably adults, would beat on the barrels, with the cat inside. This was to ward off evil doings.
I have never attended a Fastelavn celebration, but I think it's cute when I see the kids get into the preparations, such as decorating the barrels.
