Our food safe, dishwasher safe patented dispenser brushes are very durable and should last a very long time. About the only reason you should need to replace the brushes is a mouse. Yes mice love treats too and a dispenser on the floor is an invitation they can't resist. So just rotate the feeder or pick it up if you think there is a mouse about...or get a cat! Note: mouse not included!
