From Saturday to July Russia is hosting the Confederations, the main warm-up event for next year's World Cup.
St. Petersburg's Hermitage Museum on Thursday unveiled Achilles, a white moggy who will be offered two different plates before each game to predict the Confederations Cup results.
The Hermitage is currently home to some 50 cats which live in the museum's cellars and catch mice. Cats were introduced to the Hermitage, then the imperial Winter Palace, by Peter the Great in the 18th century. Catherine the Great officially made the cats guards of the royal picture gallery.
