I used colorful paper strip as prey and uneven quilt as ground. Emma hided behind the quilt and gazed at the prey. Her round eyes was wide open. Once the prey got into the attack zone, she would go up immediately. Sometimes the prey could also resist and escape if it could not defeat her. Emma escaped to the windowsill and would move out again when there was a good chance. Sometimes the sly prey also attack from the underneath of the quilt, but surely it could not escape from vigilant Emma. Emma would adjust her pose into attack mode quickly after she found something abnormal and then would caught the stealthy attacking prey.
Because the camera was held by hand, some sections were presented with shaking. If it made you feel uncomfortable, please forgive me.
