"I was skeptical after trying 2 other fountains that didn't work. My 8-year-old Maine Coon, Oliver, had already been to the emergency vet twice for blockages ($4,200 total). My vet mentioned the Pawira specifically and said it was the only one she recommends because of the special coating. Within 3 days of setting it up, I could hear Oliver drinking throughout the day - something I NEVER heard with the other fountains. It's been 8 months now and zero problems. The peace of mind alone is worth every penny. Don't waste time with cheap pet store fountains like I did." - Linda
