Thirst

There's that scene in the movie Vacation when Clark finds his way out of the desert and he is about to die and his family says they are hungry and he says in a raspy voice that is in dire need of liquid "I'm so hungry I could eat a sandwich from a gas station!"

This reminded me of that.
In a roundabout way.
Because this is a cat.
At a birdbath.
But it is hot out.

"I'm so thirsty I could drink out of a birdbath!"
