Laurence Higgins, an enormously fat black cat, has breakfast with Mrs Higgins, lunch with the Normans, tea with old Mr Mason and supper with the Barclay-Lloyds. None of them know why he is so fat on just one meal a day! Lawrence is happy until he finds the walking from house to house tiring and begins to get indigestion. His friends tell him to lose weight if he wants a girl friend so he begins to spend one day in four with all his owners. He gets thinner but the cat he fancies down the road tells him she doesn't like slim boys - she's lost her heart to an enormously fat black cat she used to see up the road! Triumphantly Lawrence returns to his four meals a day, spurred on by the thought of meeting Bella when he's back to his normal size.
