Pierre and Eliane Thivillon based in Lyon France, took the gorilla named Digit, in when she weighed barely four pounds and six ounces.
18 years later, the Thivillons have been restricted to their home for 13 years since they cannot leave Digit with anyone or take her out with them.
Surprisingly, they couldn't be bothered as they have raised her like the child they never had.
The Thivillon's bottle-fed and house-trained Digit who is now a teenager weighing almost 13 stone.
Back in 2013, Mr Thivillon disclosed the nature of their reclusive lifestyle, revealing that they have not gone out in 13 years.
"We cannot leave Digit overnight with anyone else, which means we haven’t been able to go out for 13 years.
"We haven’t had a holiday, or a night away. We haven’t been to the cinema, the theatre, or out for dinner. It would make Digit sad if we weren’t here, and if she is sad we are, too."
Now, Digit lives in an enclosed space attached to the couples home as they also run a private zoo close to their home which has become a sanctuary for animals rescued from poorly run zoos and circuses.
Their zoo is now home to over a thousand animals including monkeys, gibbons, snow leopards, tigers and lions and eight other gorillas.
