PreS-K Ben desperately wants a pet and requests a dog, a cat, a monkey, a parrot, or a hamster. Each animal is rejected by his parents: ``cats. . .steal food from the refrigerator,'' ``parrots . . .say terrible things,'' etc. In a vague and confusing conclusion, Ben finally finds a pet that is acceptable to alla city pigeon who requires only a scattering of crumbs. Chapouton's book lacks the originality and humor of Steven Kellogg's Can I Keep Him? (1971) or Martha Alexander's No Ducks in Our Bathtub (1973, both Dial). The mixed media illustrations are colorful but stiff, lacking any sense of animation. Perspective is inconsistent from one illustration to another. Ben's parents are forever scowling, and Ben is reminiscent of a Charles Schultz cartoon figure. Mary Beth Burgoyne, Mesa Public Library, Ariz.
