This environmentally friendly product attaches to a water or soda bottle. Bottles from Dasani Water and Pepsi fit best. Remember to remove the plastic ring around the bottle neck to ensure a proper fit. The size of the stainless steel ball ensures that a sufficient amount of water will be consumed without any excess effort on your Pet’s behalf. It is constructed of a very sturdy plastic, making it super easy to clean. It features a snap-on and snap-off device with 2 different height settings. We’ve used this product for some time now. It surpasses every water bottle available on the market. After years of having water bottles continually drip and spill, we found this one to be the absolute best. Ordering 12 or more?
