Query: My cats are big fans.

I received the fountain 3 weeks ago and cats are already big fans. They stopped jumping up to the sink and begging for water from faucet. Took them about 1 week to make the switch away from their bowls. The fountain is very quiet and was easy to set up. The included large reservoir with this platinum model is a great feature because I only need to refill about 1-2 times per week.
