Chester zoo resident, 23, ‘back to her usual feisty self’ after electrochemotherapy for tumour in her jaw

A 15ft (4.5-metre) python is believed to be the first snake in the world to be given a pioneering, life-saving cancer treatment normally used on humans.

The 50kg reticulated python, named Jodie Foster after the Hollywood star, has just turned 23 and lives at Chester zoo. Keepers first became concerned that she may be unwell when she began eating less and spending more time inactive in her habitat.
