Query: Drinkwell Pet Fountain

The product works well and my cat now likes to use it. Originally, the cat was wary of the hum of the pump and the moving water fountain. She was definitely curious about this new contraption and would not drink out of it while the water was running. So I plugged the Pet Fountain into an electric timer and set it to run when I knew she would be sleeping. My cat now routinely uses the fountain for drinking (when it is the OFF cycle). Good product, I like it and feel safe leaving my cat unattended for four or five days.
