I've had both the Drinkwell and the PetMate. My cats prefer the Drinkwell, since it pours into the bowl as opposed to trickling down into it.

My cat Bad @$$ Buddy LOVES the bathroom sink faucet. It's sort of a morning ritual with him. That and his "sippy" of half and half when I make my morning coffee.

The Drinkwell is a little more expensive but well worth the investment. I recently purchased a used one on Ebay because I had the $30 reservoir to my old one and it holds a lot more water. One suggestion would be to buy a used one on ebay and give it a try.

Good luck!!
