1 Green Soda Pop Water Bottle Bird Drinker Cup & Spring

1 GREEN in color soda pop/water bottle fountain drinker with bottle mounting spring. 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 drinker lets you use a bottle hanging on the outside of your bird and small animal cages. The drinker is of smooth plastic, threads securely on the neck of 20 ounce, 1 liter, and 2 liter plastic soda bottles, and water bottles that have the same threads as a soda bottle. Does not thread onto flimsy Wal-Mart style 16.9 ounce bottles with the small fine threads. A spring is furnished for looping around the bottle to hold it on the cage. Spring is not a good fit with 2 liter bottles as the bottle is big. Might want to cut up a coat hanger if using a 2 liter bottle. Spring works best with 20 ounce or 1 liter soda bottles. Easy to refill, easy to clean. Fits thru a 1.5 inch squared or larger cage opening. I
