I bought this to test out in my large guinea pig indoor enclosure, the it is in the same room that I sleep in and the traditional water bottles for rodents are really noisy and keep me awake at night. I positioned in the corner of their cage so that I could cover the electrical wire easily and fasten it out of reach so it couldn’t be chewed. The noise from the water fountain is hardly noticed during the day, and at night the gentle sound of rippling water is a huge improvement on the metal clanking noise of the water bottles ideal for drifting off to sleep. It even looks cute like a little water feature for them.
