Ethical Products Wigglin’ Snake Cat Toy has a realistic, slithering motion that entices even the pickiest cat to play. Charge it, turn it on and watch it go. The realistic slithering motion mimics a real snake and motivates cats to instinctively hunt, chase and catch. The smart sensors detect and avoid obstacles, so the toy automatically changes direction to keep moving. An automatic sleep mode is activated when cats stop playing, and with a wave over the snake’s head sensor will reactivate.
