A tiger at a Cambridgeshire wildlife park required an armed escort when she had life-saving surgery to remove a tumour the size of a rugby ball.
Amba was accompanied by police and a firearms team for public safety reasons when she travelled to a veterinary hospital in Cambridge last week.
Shepreth Wildlife Park, based nearby, said the 27 stone (171kg) tigress had recovered well from the operation.
She is now back at the park, where she has lived for 10 years, it said.
Amba showed signs of bloating in early October but the park said it was not initially concerned because the animal is bulk-fed up to 15kg to mimic her natural dietary behaviour.
But after the bloating did not go down, 12-year-old Amba was taken in a specially-built steel crate, with police and the park's own firearms team on standby, for her first ultrasound.
The ultrasound suggested a possible tumour deep in her abdomen.
