Reliving the nightmare she said last night: ‘I feel lucky to be alive. Everything happened so fast. One minute I was petting a tiger’s back, the next it turned its head and knocked me to the ground with its paw.
‘As it lunged with its teeth I felt an agonising pain on the inside of my left thigh above my knee. What happened next is a blur. But a keeper jumped in between myself and the tiger. Then, while the keepers pulled the tiger to stop it attacking me further, my older sister Georgie dragged me.
The stunned teenager added: ’When I looked down at my leg it was terrifying. All I could see was blood.’
Two friends in their group immediately tied a tourniquet round Miss Brennan’s leg to stop it bleeding.
Meanwhile, the Human Sciences student who is studying for a degree at University College London was rushed to Thailand’s Kanchanaburi Memorial Hospital where she needed ‘tens of stitches’ to repair the four-inch wound.
She then had to remain in hospital for a fortnight after contracting an infection and high fever.
Her sister, 21, was forced to make the call to parents Margaret and Nick Brennan, 56, an architect.
Mother Margaret Brennan, 52 a former nurse who now runs her own business, said: ‘When Georgie rang the first thing she said was ‘firstly Isabelle’s ok’ but I was very upset. I couldn’t believe it when she said Isabelle had been bitten by a tiger.’
But finally after a gruelling two weeks in hospital – when she was pumped with strong antiobotics - she was well enough to fly back to the UK.
