Ka'at scouts Tiro and Mer, on earth to rescue their four-footed kin before barbaric humans destroy the planet altogether, pick up two inconvenient charges of their own in orphaned, miserable Jim and homeless Elly. The ka'ats are at first reluctant to take responsibility for having made mind contact with the children--"the boy has taken you into his liking. . . I would say he has claimed kinship." As for Jim and Elly, who can blame them for being impressed by the inside of a feline spaceship? But their joy at being adopted as pets by a pair of cerebral ka'ats ("now that the decision was made he was beginning to feel free. . . everything would be ever-lastingly all right from now on") leaves us feeling uneasy. In any case this pair of pontificating pussies rubs the wrong way.
