Cee-lo Green - Animal Rights Activists Urge Cee Lo Green To Give Up The Bird

The Forget You singer has traded in his white cat, Purrfect, for the bird, which will sit on his shoulder during the audition rounds of the upcoming season of the show - but the idea doesn't sit well with experts.

Born Free Usa spokeswoman Monica Engebretson tells the Globe tabloid that Green should have done his homework before adopting the cockatoo as his sidekick.

She says, "They're beautiful, intelligent animals but they are very challenging to care for and are prone to considerable problems. They develop self-destructive behaviour, including feather plucking and self-mutilation.

"I encourage The Voice (producers) to promote a more appropriate companion animal."
