The stray cat that turns up on the doorstep may look ""like mashed prunes,' but Henry's huge dog likes it--though, as Dad is quick to point out, Mudge also likes turkey gizzards. The cat strikes up a relationship with Mudge that is close, funny, and--to anyone who has ever observed such a friendship--charmingly realistic; then, in a refreshingly unclichÉd conclusion, the cat goes back to his previous owner. This may be the best yet in Rylant's popular series. Freshly original, natural-sounding language, an engaging stow, and Stevenson's deft but informal illustrations combine in a notably affectionate adventure.
