I received the Drinkwell® 1 Gallon Pet Fountain to review. This is a fancy little drinking fountain for my cats. I love how it filters the water because animals drinking water can get nasty. I was a little skeptical at first, as my little cats didn't want to drink from it because of the noise. After a couple of days they adapted to it and all is ok. I hope there is a larger size available as I have 3 cats. Great product!
