There's a place called The Duke of Perth, just west of Wrigley Field, and the Cubs' caterer will work with them to have haggis in the reserved suite at the ballpark for our kitties :) I believe U.S. Cellular Field uses the same caterer, so I would think they can deliver to the kitties' sky box there as well.
By the way, the Cubs' front office has also extended an invitation to our pipers and dancers for both the National Anthem and the 7th Inning Stretch.
