Nora the cat purrr-fect on piano

Nora the piano-playing cat is living the Hollywood life in Philadelphia.

Fresh from a Lithuanian concerto written just for her, the YouTube sensation gets fan mail by the bushel, has her own groupies and could be an addict if her owners ever forget to put the catnip away.

The 5-year-old tabby’s latest cyber splash was Lithuanian conductor Mindaugas Piecaitis’ first composition, featuring Nora’s solo video performance in what he called his CATcerto.

The performance with the Klaipeda Chamber Orchestra has become a Web sensation at www.catcerto.com, with hits closing in on 1 million.

In all, nearly 20 million people have watched Nora play. She has made the television talk show circuit and has videos, two books, her own Web site, a blog, three calendars, mugs, greeting cards, T-shirts and posters under her belt.

Nora is owned by piano teacher Betsy Alexander, 53, and her artist-photographer husband Burnell Yow. They live in a house splashed with floor-to-ceiling color with five other cats: Gabby, Max, Rennie, Miro and Clara.

Alexander said Nora, a photogenic, green-eyed shelter cat, has been a diva as long as she’s known her.

In fact, the day they found each other, at a Cherry Hill, N.J., shelter, there was a sign on Nora’s cage that said “bossy.” She doesn’t like other cats.

Nora has an agent, her own photographer and an entourage. But she isn’t into bling (make that collars) and she doesn’t like riding in a car – even a limo – or a plane.

“She loves visitors. She is a very gracious performer and she feels indebted to her public,” Alexander says.

Nora doesn’t play just any piano, she plays a Yamaha C5 Disklavier – a Lamborghini of a piano, Alexander calls it.

Most of her performances come when someone else is playing the turn-of-the-century, ivory-keyed and restored Briggs piano next to the Yamaha.

“She plays in rhythm and on key,” said Alexander, who has been teaching piano, guitar, voice and composition since sixth grade. “She plays in the same area of the keyboard as the person on the other piano and when the student stops, she stops.

“More often than not, she is in the same octave as the student. Sometimes she plays loudly, softly, quickly, slowly.”

A music teacher in Japan wrote to say Nora had superb technique and that she used the cat as an example to her students on how to strike the keys. Nora releases the key instead of pounding it, Alexander explained.

Nora purrs when she plays. And when she dances, it is in circles on top of the grand piano.

When she was young, she chased her reflection so long she would get dizzy and fall off the piano, Alexander said. These days when she gets dizzy, she just changes direction.

Nora does have one little problem.

“She loves to eat,” Alexander says. “She will eat as much as she possibly can.

“She’s not picky either – fried chicken or filet mignon. She’s like a little bowling ball, just roly-poly, like a seal.”

Her size hasn’t affected her popularity, though.

Alexander is putting the finishing touches on a gift book called “Nora the Piano Cat’s Guide to Living the Purr-fect Life,” and Nora also has received offers from magazines, cat toy manufacturers and fellow musicians.

Alexander has been swamped by cat owners who want her to teach their cats how to play.

Nora has gotten thousands of e-mails and thousands of letters from all over the world. She is constantly asked for her autograph or pawtograph, as Alexander calls it.

“We tried putting some food coloring on her paw but she didn’t like that at all,” Alexander says.

She’s had offers of marriage, notes of encouragement and video messages.

“It’s wonderful mail,” says Alexander. “One woman who runs a music camp wrote and said her 13-year-old daughter had quit piano lessons but when she saw Nora, she started up again.”
