Groucho...Meows and purrs from Buddy. My maw has one of these things too. The other 3 cats hide when she gets it out but I am still trying to figure the thing out so I lurk around while it is running. All I know is that everything gets picked up off the floor and yes sometimes some of my good stuff is sucked up into that thing! I had a string I like to play with and also a piece of cardboard that came off of some box. They are gone now. It hasn't sucked up my food yet though. whew!
