Born on the same day as Britain's royal baby, three rare albino hedgehogs have been given their own miniature castle at a Moscow petting zoo.

George, Alexander and Louis, who share the Prince of Cambridge's first names, are proving popular with the zoo's young visitors, the BBC reported.

On Thursday, the tiny triplets were introduced to their new home at the All-Russia Exhibition Center.

The wooden castle is painted purple, with curtained windows and a plush bed inside.

A red carpet was rolled out to welcome the babies and their parents, the Associated Press reported.

The zoo is hoping that Prince George himself will visit the hedgehogs one day, spokeswoman Yevgeniya Polonskaya told AP.

An albino African hedgehog gave birth to the babies, Polonskaya told Russia's RIA-Novosti news agency in July.

"Albino hedgehogs don’t usually breed in captivity," she was quoted as saying. "If people keep a standard hedgehog at home, it might give birth, but to no more than two babies. But we saw the arrival of triplets on July 23."
