A stray kitten called Lucky survived a three-day journey from France to England inside a car engine.
Lucky crawled into the car before Alan and Audrey Plumpton travelled home from their holiday cottage in Brittany.
The couple only discovered the six-week-old French cat when they heard mewing from under their car bonnet after arriving home in Amersham, Bucks.
Lucky will be reunited with the couple after spending six months in quarantine with the RSPCA.
The kitten was trapped in the engine compartment of the car for three days as Mr and Mrs Plumpton made a 280-mile (450km) car journey home from their cottage in La Briere national park.
Lucky was handed over to the RSPCA after Mr Plumpton found him in the car when he arrived at his home in Stubbs Wood earlier this month.
Mr Plumpton said: "I cannot believe Lucky managed to survive for three days in our car engine. The first we knew of him was when we heard crying and saw two little blue eyes staring out from under the bonnet.
"We decided to keep Lucky as he used to play, along with some other feral cats, near our cottage and obviously took a liking to us. It would seem a shame to turn him away now after he made such a long journey."
The cream and grey coloured kitten is now in quarantine.
A spokeswoman for the RSPCA said: "This cat really lived up to his new name.
"He was very timid and took us a while to get him into the cage but at least he now has a brand new home waiting for him when the quarantine period is up."
