Green, who's a vegetarian, said she often has trouble seeing the animals when they're sent off to slaughter, and will use any extra to donate to the sanctuary or save another animal from her father's farm.
"Lambing time is my favorite and it's often very difficult to say goodbye to the lambs," she said. "I really dread seeing trailer loads of cows on their way to the abbatoir."
In any case, she's determined to secure her gentle friend the "long and spoiled life she deserves."
"I made a promise to her that I wouldn't let anything happen to her," Green said. "I hate lying to people's faces so once I said it there was no going back."
