1PC SODA POP OR WATER BOTTLE FOUNTAIN DRINKER CUP WITH SPRING QUAIL CHICKEN BIRD This listing is for 1 White in color soda pop/water bottle fountain drinkers with bottle mounting springs. Simply connect your old soda or water bottle to the fountain and you are giving your bird/pet a waterer and keeping your soda bottles out of a landfill. For convenience and economy. This fountain lets you use a bottle hanging on the outside of your bird and small animal cages. The fountain is of smooth plastic, snaps securely on the neck of some 12 to 16 ounce bottles and projects through the wire 2 inches inside the cage. A spring is furnished for looping around the bottle to hold it on the cage. Easy to refill, easy to clean. Fits thru a 1 inch squared or larger cage opening. If you cage has squared openings smaller than 1" no big deal, just snip out the wire to give you a 1" opening. NOTE: This will not work on coke and pepsi plastic bottles with the new eco friendly caps. The threads on these new bottles are too short to reach the base of the waterer. These drinkers work best with real glass 12 oz pop bottles. They still sell them in grocery stores. They also work well with some plastic bottles but they need longer threads to reach the base of the waterer. A lot of off brands have the longer threaded cap ends. Eco frindly bottles DO NOT WORK.
