The most efficient and easy to clean
So far, this is the best fountain I've ever had over the years. It has exactly what I was looking for:
- motion sensor, so it doesn't run all the time, only when the cats want it
- no external wires, the battery lasts 3 weeks on motion sensor mode
- no pump or wires in the water, where all the bacteria and slime gather and are hard to clean
Anyway, I clean it completely and change the water every 3 days. You can place it anywhere in the house. I have two for my two cats.
But it's gotten really expensive, I bought it for 400, now it's 600.
