Can you feed all the cats in the world?"" the elderly lighthouse keeper taunts also-elderly Mikila, who faithfully feeds the promontory's hungry horde each day. She has thumbed her nose (literally) at his taunting; she has persevered in foul weather to prove her mettle. Now, feverish and despairing, she takes to her sickbed . . . only to rise, on the fourth day, newly determined--and discover the lighthouse keeper himself feeding the cats. His goat, he says ""with a grin,"" heard the cats making a racket. And he's had the same thought as she: feeding the cats is much like ""tending the lighthouse."" (You can't, that is, save every ship either.) A modest, not particularly prepossessing book (in sandy beige and gray-blue) with two clear attractants--the cats and the squabbling pair--as well as an unusually genuine argument.
