I found a stray cat and have been taking care of it for three months, and it gained some weight.

One day, it suddenly disappeared, and I searched the entire neighborhood.
I posted a lost cat notice and offered a reward of a thousand yuan.
The next day, someone knocked on the door; it was a young girl holding my cat in her arms.
She said, "Brother, is this your cat?"
I said, "Yes, yes, yes, thank you."
I took out a thousand yuan and offered it to her, but she didn't accept it.
She said, "I don't want money."
I asked, "Then what do you want?"
