PBF  Pop Bottle Fountain
Pop Bottle Fountain - PBF
Lets you use a common pop bottle hanging on the outside of your bird and small animal cages. The fountain is of smooth plastic, snaps securely on the neck of the bottle and projects through the wire 2" inside the cage. A spring is furnished for looping around the bottle to hold it on the cage. Easy to refill without opening the cage. Made for glass or standard size bottles; does not work well with 2 liter bottles.
