Katy Perry Hires A Cat Whisperer

The singer's cats, Kitty Purry and Krusty, have been so badly behaved that she's been forced to hire a cat whisperer!

Katy told US Weekly that her feisty felines have been giving hubby Russell Brand a hard time while she's been away on tour and had to call in a professional.

"He realigned their chakras and did some hypnosis. We were like, 'Wow, this is extravagant!'"
