Two of our cats were in the storage room knocked over the Christmas tree box while hades was in the litter robot when I got down there it started rolling while she was in it thats why I started to record, but ya the cats got spooked and hades is healthy, happy and spoiled along with our three other cats, this was like the first week of us owning the litter robots, it works great and all the cats use it, thank you! Man caught his cat inside the automatic cat litter where it started rolling and got buried on the cat litter sand, then jumped out from the cat litter
