The slow feeder system is built with high quality ABS plastic which is, non-toxic, and Eco-Friendly. Its unique Rotatable Feeding Trough design, slows down your pet's speedy eating habits by requiring them to perform an action in order to get the food to fall down to the Maze-Plate which will then require them to do a little thinking and show a little agility before they can finally get the food to eat. Keep your pet's weight under control by slowing down their eating speed.
