Her first blanket
The team had to find a way to save Dongsuk and her kitten. They also knew that this required a strong bond of trust with the mother cat. To accomplish this, they returned to the location to which the cat previously led them. There they gave her a blanket.
This was the first step in building a bond of trust between cat and human. They wanted to show that they were not the enemy. However, Dongsuk and her daughter were not going to trust the team in one day.
