The cats have me trained

Our cats will drink water from everywhere but their water dish. At least one cat also has the annoying habit of tipping over glasses of ice water and vases of flowers in order to get a drink.

I've given up trying to train them. Here's how they've trained me:

1) I put floral arrangements only near sinks, for easier clean-up.
2) I created a kitty-friendly floral dish (see above picture).
