Emma has a new toy, which is a ball made of entangled rope. The ball should be the subject for Emma to play, but it seems Emma dislikes it and she run away for refusal. Then I threw the string connecting the ball to Emma. However, she liked it very much and chased the string everywhere. She grabbed it with her paws, bite it with her mouth, and played happily. Sometimes it’s better to change the way of playing a toy.
