Query: Perfect to slow down eating

These are great! They force your cat to eat slower and my cat actually enjoys pushing it around to get food! I can put food in her dish and in the feeder ball and she'll go to the feeder ball. However, I was feeding her exclusively with the feeder ball and it got to a point where she would bat it around until all the food was out of it then walk out of the kitchen without eating any of it. I don't know if she was in a tizzy about something or not but I stopped using it for a while and try to switch it up now. I also had to get 2 of these because there would be times that I couldn't find the ball because it would end up in the other room. Now I have two cats and I use them both at the same time and they're pretty good about keeping them in the kitchen and surprisingly not leaving a mess, as of lately anyway.
