Cat's adventures continue in Catspaw, published in 1988. Although Cat had thought himself safe once he had acquired a databand, he soon discovers that money is more powerful than citizenship. Cat is once again forcibly employed, this time by the ta'Ming combine. He is supposed to guard a politically active member of the combine, Elnear. By the end of the book Cat has attained a certain amount of serenity and security as absolute as Elnear can manage. Cat also appears in a short story "Psiren," published in the 1985 collection Phoenix in the Ashes.

"Psiren" is set after the events of Psion but before Catspaw. In this story, Cat rescues a Hydran woman from slavery.

In the end, she rejects him because he has seen too deeply into her soul, leaving him hurt and still "deaf" to telepathy. Both Psion and Catspaw were published in an omnibus edition...
