Someone remarked that every cat is always at his/her best. The very best cat it could possibly be.
I've said something similar but it was not original.
From The Wicker Man, Lord Summerisle, played by Christopher Lee (now starring on the $20 bill):
"I think I could turn and live with animals. They are so placid and self-contained. They do not lie awake in the dark and weep for their sins. They do not make me sick discussing their duty to God. Not one of them kneels to another or to his own kind that lived thousands of years ago. Not one of them is respectable or unhappy, all over the earth."
