NORA, the cat who shot to fame after a video of her playing the piano was posted on Youtube, checked herself into the Priory Hospital last night.
Friends say she is recuperating at the North London clinic after shaving off her chest fur with a Bic razor and trying to drown herself in a sink.
Owner and manager Sally Winston said: "She's been under enormous pressure since we discovered her amazing talent for leaning on piano keys with her paw and the side of her face.
"Instead of using her litter tray she would smear excrement over the walls and have staring contests with the hoover.
"Then she stole our car, drove it to Las Vegas and married a bugle-playing West Highland terrier that she met on Oprah."
Nora had recently signed to Simon Cowell's management company for £4 million worth of mackerel and long bits of string over three years.
Following her suspected suicide bid, Nora will be cared for by therapists specially trained to deal with animals who become famous as a result of poorly edited internet videos.
Animal behaviourist Dr Julian Cook said: "Famous animals frequently develop psychiatric problems. Well 'Ard from Eastenders claimed to be the reincarnation of 15th century alchemist John Dee and would wander around the set in a tricorn hat, growling in Latin.
"One particularly tragic example is 70s TV bear Gentle Ben who, as his fame evaporated, began to sexually predate on emus and was finally kicked in the face at the West Midland Safari and Leisure park."
Meanwhile Winston has been forced to postpone Nora's 50-date stadium tour to promote her new album Humans, Do You Have Food?
