This thing is fun, just right for small pets. I tried using a plastic soft drink bottle as illustrated on the box - it collapsed. A glass bottle is required. I used a 1-1/2 liter wine bottle (the wine was awful), but there should be several good glass bottle choices in your grocery store. My normally foolhardy little terrier jumped back the first time the water in the bottle gurgled, but he got used to it quickly. I purchased two more to give to friends - they were delighted.
