According to The Sun, the zoo has lost its accreditation due to inadequate care of the animals. Losing accreditation may not make the operators decide to clean up their act.

But losing business will. Please send the message to everyone you know and urge them to boycott this zoo until we hear from credible sources that the zoo has made permanent and satisfactory improvements which give good quality of life to its animals.
