About Casimir

Concord Casimir is an orange cat who makes an annual prediction at Ellison Creek Knob in Concord, Ohio. Casimir — aka, The Polish Prince of Felines — was found abandoned as a kitten on the footsteps of Cleveland’s St. Casimir Polish Church in 2012. Master of Ceremonies John Niedzialek interprets Casimir’s forecast based on the way he eats his yearly pierogis. If he eats them sloppily, Cleveland is in for a long, messy spring; if Casimir eats them normally, then it’s winter as usual; and if he swallows the pierogis in one gulp, the region can look forward to a warm coming summer. Since Casimir’s predictions are a little unconventional, we try our best to fit them into the “spring/winter” dichotomy we prefer on
