The Gravity Drinking Bottles are made from durable recycled bottle material. They are totally quiet as they work with gravity and this design has no metal balls in the tube. These are reduced to clear, if you would like more, please contact me and I will give you a price for my remaining stock
TIP! We recommend that you always make at least two bottles available to your rats at all times, preferably of different types, in case one gets knocked off, leaks, gets chewed or is faulty, you know you have a back up!
