I have a drinkwell fountain and Sunny and Storm love it. They still drink from their old watering hole too. Pepper hasn't used it yet but I've noticed that all 3 of my guys are drinking a lot more water these days which is a good thing especially since they are males. I also bought the attachment so it holds more water. I use bottled water because my water is very hard and the instructions said that this could wear out the pump. I bought mine at Petco. Here's a picture of Sunny drinking from the fountain.
