Rail company c2c is searching for the owner of a chinchilla that was found on board a train that left Southend in Essex.
The little animal was left on the train late on Monday night in a box without any bedding or food.
She was eventually found and taken in by a member of staff.
A c2c spokesman said: “A chinchilla isn’t the sort of passenger we would normally expect to be travelling on our trains late at night.
“We’re also not sure whether she had a valid ticket to travel. Poppy, as she has been named, is being well looked after by a member of c2c staff who is keen to adopt her if her owner doesn’t come forward.”
