Reading the reviews, this seemed like a good purchase. We bought it, followed all instructions setting it up and put it up and running 3 days ago. The pump is about as loud as a fridge and randomly gets very loud, where I can hear it from the other side of the house. Takes a small tap with my foot to make it quiet down.Needless to say, the cats are scared to death of it. They have not tried to drink from it, and when they walk by it they try to put as much distance from it as they can. Just I begin think they are not as scared of it, it gets VERY loud and they start to freak out again. For $40 bucks, this is ridiculous. This will be sent back.
