T.s. Eliot said this quote

“ Before a Cat will condescendTo treat you as a trusted friend,Some little token of esteemIs needed, like a dish of cream;And you might now and then supplySome caviare, or Strassburg Pie,Some potted grouse, or salmon paste —He's sure to have his personal taste.(I know a Cat, who makes a habitOf eating nothing else but rabbit,And when he's finished, licks his pawsSo's not to waste the onion sauce.)A Cat's entitled to expectThese evidences of respect.And so in time you reach your aim,And finally call him by his name. ”
