London Zoo not to blame for death of Sumatran tiger: Manager

London Zoo on Monday denied it was responsible for the death of an endangered Sumatran tiger mauled by a potential mate brought in as part of a breeding programme.

Staff were left "entirely distraught" by the death of the tigress, called Melati, the zoo's manager said Monday, rejecting suggestions they had not waited long enough before allowing the animals into the same enclosure.

Zoo staff held Melati, 10, and Asim, 7, in adjacent enclosures for 10 days before allowing them on Friday to try and breed as part of a Europe-wide programme to help boost the numbers of the endangered animal.

"Several people from outside the zoo have remarked that 10 days seems fast to introduce tigers to each other," Kathryn England, chief operating officer of the Zoological Society of London (ZSL), told staff in a letter published on her blog.

"It's not -- it's wildly variable and depends entirely on careful observation of their behaviour.

"Conversely, it can be risky to leave tigers showing an interest in each other out of contact for too long, leading to a build-up of tension and frustration," she added.

The pair initially watched each other, before rearing up - "all quite a normal part of them testing their boundaries," explained England.

"But in the blink of an eye, with no obvious provocation, they turned on each other.

"Asim started to retreat and we were poised to close the gate when Melati lashed back out at him. He overpowered her in a split second."
"Our vets ran to Melati...and even these experienced professionals...were entirely distraught."
She hoped the publicity surrounding the incident would "trigger a greater understanding of the challenges faced by her species in the wild."
