Cheeky cat!

We had a friend over for dinner tonight and he brought flowers. Just as I was about to go to bed I looked at the table and my cheeky cat was drinking the water from the vase! Tap water here is not drinkable because all our water is desalinated and that hasn't gone thru as many desalinations (is that a real word?), so it is still a bit salty. The cats have drinking water (called "sweet water" here) in their bowls but it's much more fun to steal the salty water from the flower vase! They quite often drink the water from the ac outside which gathers in a dirty green bowl! But the cheeky cats turn their noses up if the water in their bowls is a few hours old and demand fresh water! And as I look across to the table she's doing it again!
