Katy Perry reportedly hires a cat whisperer to comfort her kitties

"Katy is getting really worried about her cats and the way they've been behaving lately," a source told the Daily Star newspaper.

"In the last couple of months they've been disappearing for hours and aren't responding to her like they normally do.

"She thought it may be a reaction to all the building works and the renovation going on in her home in Hollywood, which is getting a huge makeover."

When Perry heard about these 'animal magicians' she wanted to give it a shot.

"The cat whisperer is now working with her cats to communicate with them and calm them down," she said.

"Katy sees her cats as more like friends than pets, so she didn't think twice about hiring the cat whisperer.

"She often talks to Kitty and Krusty when she's feeling down, and they always manage to cheer her up. The fact they've been acting weirdly has really bothered her. She doesn't mind how many sessions she has to pay for, she just wants things back to normal."
