Sorry no video available yet but my cat is quite taken with the new treadmill we recently acquired. He began sitting on it & we didn't want to scare him so left him alone, but one day I couldn't resist & on the lowest setting, turned it on. What does he do? Sits perfectly still while he moves backward along the tread. Doesn't even turn to see what is coming.
A few days later & this has become a favourite game. He still doesn't look to see where he's going, but he has begun walking on it sometimes, which is a giggle. Soon enough he'll be pacing out his steps to match the speed of it alongside me while I take some exercise
