Chester Zoo's three nine-week-old Tiger cubs have had their first ever health check ups. Last week, the rare cubs were checked by zoo vets and keepers who determined their sexes, wormed them, fitted them with microchips and gave them their vaccinations for cat flu.

Curator of Mammals, Tim Rowlands, said: "They basically receive the same vaccines that a pet cat is given when it’s taken to the vets. The only difference is we're much more cautious about handling the cubs than we would be with domestic kittens."

Each of the cubs – which are only found on the Indonesian island of Sumatra in the wild - was also weighed and given a general check up. Vetinary Officer, Livia Benato said: "The cubs received a physical examination to check they are healthy and in good body condition. Happily, all three cubs – all girls - have been given a completely clean bill of health."
