Isso pode ser James Kahn s " World enough and Time " (que é fantasia dos anos 80 e tem um gato / híbrido humano). De uma revisão da Amazon :
Along the way, Joshua and Beauty make new allies and defeat many enemies. Among the former are Isis (part teenage girl, part black cat), Jasmine (a centuries-old Neuroman, essentially a robot driven by a human brain), Lon (a magnanimous and stately Vampire), and Sum-thin (another Neuroman with a taste for philosophy and opium). Among the latter are Jarl (a huge, talking bear king), Poseidon-worshipping religious fanatics, more Accidents, a genetically engineered dragon, some evil scientist Neuromans, and - of course - the three original villains who had kidnapped Rose, Dicey, and Ollie. Of these, Isis, Jarl, and all of the Vampire characters are sharply defined and interesting.
Embora esta seja a primeira parte de uma trilogia ("New World Trilogy") você provavelmente vai querer pular as partes dois e três ("Time's Dark Laughter" e "Timefall") que são tão desajeitadamente escritas, mas perder o charme ingênuo da primeira parcela.
Aqui está outra revisão divertida (não leia se você quiser manter boas lembranças do livro) de um leitor que não ficou particularmente feliz:
World Enough, And Time (1980) is the story of a post-Apocalyptic fantasy world, in which genetically-modified monsters threaten to wipe out the remaining population of humans.
[...]
Having chapter after chapter of lengthy, pseudo-scientific rationalization doesn't help me suspend disbelief, it merely bludgeons to death any lingering excitement I may have had.

As the book limped to its action-packed, yet ultimately meaningless, conclusion, I was stunned to find an ultimate reveal of... nothing. The big bad fizzled, the relationships built on the journey dissipated (there was a lot of shagging about for a pair of married men), and everything culminated in a lot of standing about and avoiding one another's gazes. Had I read this book backwards, it would've essentially been exactly the same story. I have no doubt that there's meaning in this - every leaf of every tree in World Enough, And Time is packed with meaning - but I have absolutely no desire to seek it out.
If there's one positive about this book it is that, although Kahn deluged the reader with world-building and philosophy, he spared us any poetry. I appreciate the self-restraint.
