4 pack of RED 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 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. If you cage has squared openings smaller than 1.5" no big deal, just snip out the wire to give you a 1.5" opening. For instance if you have a 1/2" spaced wire cage you snip out 3 by 3 squares giving you a 1.5 x 1.5 inch opening.
NOTE: This will thread right both coke and pepsi product plastic bottles. This unit has been fully updated by us at Rite Farm Products to thread right on to todays plastic soda bottles. We have even updated the drinker cup side of the drinker as well giving the drinker a larger opening and depth to be useful for a larger variety of birds and pets. Works with any pet bird, quail, pigeon, dove, chicken, hamster, and many other pets and birds. New model is 4 inches long overall x 1.5 inches wide x 1.75 inches on the threaded side high overall. 1.5 inches high on the drinker side with a 1.25 inch wide drinker cup that is 1.375 inches deep.
