We're heartbroken by what's happened. To go from the excitement of the birth to this in three weeks is just devastating.
Melati can be a very nervous animal and we didn't want to risk putting her on edge by changing her surroundings or routines, in case she abandoned or attacked the cub.
At the time we thought it was in the best interests of Melati and her cub to allow her continued access to the full enclosure as normal.
We would do anything to turn back the clock, and nobody could be more upset about what's happened than the keepers who work with the tigers every day. They are devoted to those tigers and are distraught.
