The Associated Press reports that a pet shop owner in Austria created an advent calendar for pets. They look just like a regular advent calendar, but behind each day, is a biscuit for pets, instead of chocolates for kids.

Heide Obermeier, who created the calendar, told Austrian television she has already sold 4,000 calendars.

About half of the calendars were snapped up by dog owners, 35 per cent were purchased by cat lovers and the rest were bought by people who keep rodents as pets, she said.
