Hello Katy Tour

In an interview with Billboard, Perry stated, "I have the guy who creates stages for Madonna working on this tour; I'm indulging my obsession with fruit and cats and designing all different outfits.

"[citation needed] The stage design featured a white picket fence, mailbox, oversized pink flamingos, inflatable plastic fruit, and a giant cat named Kitty Purry that glowed during the encore.

A stage-prop of a massive cat’s head would glow as Perry covered Queen's song "Don't Stop Me Now".

The Orange County Register called the tour "a surprisingly strong performance" in a positive review.
