Query: It's a Miracle Worker

My cat ended up at the emergency vet on a weekend with a $750 bill. He had a urinary infection from not drinking enough water. My Vet recommended purchasing a fountain. I researched various fountains on the Net and settled on the Drinkwell Platinum Pet Fountain. Nothing but the best for our boys. It has been a life saver. He loves his fountain along with his brother and voila no more infections. You do need to clean it thoroughly once a week and we replace the filter every week also. This weekly maintenance is the most loving thing we can do for them and a lot less expensive than vet visits and meds. We don't mind at all. Our fountain is about 2 years old now and it still is working like new.
