Lauricella said if Polly can't find her or if there are too many people in the house, she gets anxious. "As soon as I put the costume on her, she [will] fall asleep. Later, I tried it again and she relaxed and fell asleep again," she said. "I realised that it had some kind of calming effect on her. ... I'm thinking it feels like a big hug." Lauricella added that Polly "LOVES to be held and cuddled".
