A calf born with additional two legs in Switzerland has become a celebrity drawing media attention.

Seven-week-old Lilli in Weissenburg, Switzerland, defied all odds and survived after veterinarians predicted the calf would not survive at birth.

Lilli's owner farmer Andreas Knutti told the Swiss daily Blick that he could not bring himself to euthanise the animal because the calf was "so full of life."

He said Lilli would not be able to milk as she has a curve in her spine. The vet who predicted that Lilly would not survive explained that the mutation was a result of twin embryos growing into one animal, with the extra legs.

Lilli is not the only calf that stays healthy despite the two additional legs. A six-legged calf belonging to Bavarian farmer Maria Suttner was born in October 2007 and still lives healthy. Not just the calves but, several animals have been born with more than four legs or have two faces.

A cat in Massachusetts, US became the world's longest surviving animal with two faces. The cat which was born in 1999 has two mouths, two noses, three eyes and one brain.
