Pretty as a Pitcher

Let’s say you could have a pitcher. You might fill it up with water
And drink eight glasses day by day, like specialists say you oughter
Or combine a batch of lemonade, for outside entertaining
Some sangria to only see ya via evenings when it’s raining
Hey, margaritas can be good, they’ll make you briefly giddy
But for delight all day and night time, simply fill it up with kitty!
