It's important when you visit our beautiful Sumatran tigers to remember just how precious they are.
They're a critically endangered species, with only a few hundred left in the wild, so we must do all we can to stop them becoming extinct.
We were delighted when our two adult tigers, Kirana and Fabi, had tiger cub triplets in January 2015. They also had two healthy cubs in June 2013. who can be found outside the Spirit of the Jaguar exhibit, by the Jaguar Coffee House.
Kirana has also given birth to sisters Nila and Tila, in October 2011. In 2012 Nila moved to Le Pal in France and Tila to Heidelberg Zoo in Germany as part of a co-ordinated breeding programme, vital to ensuring the survival of Sumatran tigers.
Sumatran tigers are the smallest of all tigers and their low stance lets them creep up on prey unseen. Their stripes are narrower and closer together than those of other tigers.
You might be lucky enough to see one of our family swimming as we often put meat on a raft floating in the water so they have to swim to it.
They have webbing between their toes, making them superb swimmers.
We hide their food in a way that is not only stimulating for the big cat but also physically demanding, encouraging them to use those big powerful muscles to find their food.
For example, we hoist food up the feeder pole in their enclosure to encourage them to hunt for it as they would for prey in the wild.
Our tigers are registered on the European Endangered Species Breeding Programme which means we work closely with other zoos on conservation breeding projects to hopefully save these amazing stars of the jungle for years to come.
