White lions are among four big cats who have just been released from quarantine after travelling to Ouwehands Zoo in Rhenen, Holland, from the Timbavati Game Reserve in South Africa. The male, Credo, is seven months old and the females, Ilanga, Bhandura and Luna, are aged ten months. White lions cannot survive in the wild because their colour stands out, not making for very good camouflage. The animals, which usually live for around 29 years, can weigh up to 31 stone (434lb).
