Areived fast as promised, I actually bought it for my cat and filled it with dreamers for her. After a while of playing with it and watching me tilting it back and forth to make treats fall out she managed to work it out herself and within an hour or so had mastered how to tilt it just so that a treat would fall out for her. I live how you are able to set the numbers in it to how fast a treat will fall out. Strong, robust and a lot if fun
