My boys love the fountain. Plus, I can tell that I'm scooping more often, so that means they're drinking more. Very healthy. I use filtered water and clean it about every week and a half.
It's the drinkwell fountain. The directions say to clean it ever 2 weeks, but with two cats, there is just too much hair to wait that long.

About catsip- its a favorite at our house. I highly recommend it. The grocery here sells it for about 75 cents.

A friend of mine buys the baby kitten milk and freezes it in little tiny tiny ice cube trays. Then gives her cat one tiny cube a day. It's like kitty ice cream, I suppose.
