The Philadelphia 76ers basketball team isn’t that good so every time they win, fans have celebrated through a bizarre ritual known as Raise the Cat. That’s when fans lift their cats over their heads and snap pictures of the confused felines in their arms, then share those photographs with their friends.

Now there’s an official Raise the Cat T-shirt that costs $20. Best of all, it’s a charity fund-raiser for the Philadelphia Animal Welfare Society. Not only can be you supporting the 76ers and their fans, but you can be helping the lives of cats in the Philadelphia area as well.
