i know this is slightly off-topic, but ever since I got one of those pet fountains my cats drink a lot more water than they used to. Might help keep Spliff better hydrated. I have the medium sized for 2 cats and I still have to fill it daily. If you have a lot of pets get a bigger one or a bubbler (like 20-25 bucks on Walmart.com) it doesn't work quite the same way but it holds over a gallon.
