Seeing A Friendly Face
The person who called the rescuers in the first place is Carey Linnell. She was there waiting by the cage and holding it open. When she saw her, Rain didn’t go into the cage, rather she slid right under Carey’s arms, snuggling up to her.
Familiar Face
It seemed like Rain had already known Carey and trusted her. She allowed Carey to pet her with no problem. Rain even went straight up to her willingly, as if she had known that Carey had called for help.
