Each time you open the toy, it will automatically turn back on for 15 minutes after the 3 hours have passed, then start again. Chat mode can be divided into two types: automatic mode and manual mode. Quiet motor, providing good environment for pets. Charging method: 4 x AA batteries (not included) or connect the USB cable. The exciting light moves haphazardly across floors and walls, appealing to cats’ natural hunting instincts. Any problem, please contact our store without hesitation. Honor to serve you!
