Grand Piano Concert -- Just For Cats!

— -- Well folks, it’s National Cat Day.

In honor of felines everywhere, take a moment to bask in this glory — a concert just for cats.

These lucky kitties in London were treated to a performance of nine lifetimes.

It’s a purr-fect symphony played on the world’s first-ever musical instrument designed just for cats.

A team of vets, scientists and sound engineers created this unique instrument as part of a protest against cyber censorship.

The electric baby grand piano plays in human frequencies and also ultrasonic frequencies—that only cats can hear.

As they recline in their plush, red chairs, the kitties purred along to songs by the Backstreet Boys and Jay Z.
