One of a litter of four, Toes the cat is born black with seven toes on each paw, whereas the other three are spotted or striped and have the normal number of digits. Their mother dies soon after they’re weaned and Toes witnesses her burial. His siblings subsequently ostracize him because he tells them what he’s seen, because of his polydactyl paws, and mostly because he’s many times smarter than they. He begins learning to understand human words, enjoying classical music, and doing “tricks.” One night, because of the treachery of his siblings, he’s shut out of the house. He stumbles into another basement and is trapped. Kept alive by a deal struck with mice, he isn’t discovered until the next spring. Sebastian, a struggling fiddle player who wants to play with the Philharmonic, adopts Toes, and they spend several happy years together. It’s only with Toes’s help that Sebastian finally achieves his goal and comes out of his shell. Seidler, writing in his Wainscott Weasel mode, has delivered an excellent, if melancholy, realistic story of a special friendship. Young cat lovers will be in heaven. (Fiction. 9-15)
