The food belt is constructed following FDA guidelines.
We love this portion control feeder... when it works. We were free feeding our dogs and 1 was overeating so we bought 2 feeders for our dogs to provide portion control. We followed the set up instructions, which were easy. The issue is that the feeders jam and we have to pull the units apart and work the food out of the belts. We are not sure why this is happening as we are using the recommended dog food size and went from 2 to 3 feedings per day so the portions being pushed into the bin are smaller. We have also ordered new belts thinking ours may be defective, but the issue continues to happen. Despite all the issues, both of our dogs have lost weight and have more energy since using this feeder.
I purchased extra bowls, along with an extra belt and food bin. Makes life extremely easy to be able to swap out clean parts, and wash the empties when I have a few minutes. Well worth it.
