WagTime Rabbit Drinking Bottle is excellent in providing your small animal with the fresh clean drinking water they need. The stainless steel nozzle can be accessed at any time of day. It works by inverting the drinking bottle, thus creating a vacuum inside. This makes it easy for your pet to control the amount of water they want access to. When positioning the bottle in your little one's enclosure, consider their weight and height so they are not crouching down or ?reaching up just to get a drink. It is important that you change over water daily.
