Cordwainer Smith is a cult figure for SF fans, and one of the weirdest and most gifted to emerge from the golden age apart from Philip K Dick. He imagined all kinds of things that might well come to pass, including the genetic adaptation of animals into a race of humanoid slaves, or Underpeople.
The moment these show any sign of illness or disability, they are killed. The Lords of the Instrumentality rule the universe with benign intentions, but having eradicated disease, war, hunger and unhappiness it all goes badly wrong.
Many of the best stories have been repeatedly anthologised (The Game of Rat and Dragon, in which a telepathic pilot works with a cat in order to destroy the deep space predators he perceives as dragons and she perceives as rats being one.) Smith's weird prose style was apparently influenced by knowing Mandarin, and he apparently worked for the US Pentagon. Apparently the other SF writers of the 1950s werre so spooked by him they thought he might himself be an alien.
What is especially fun is that each rich, densely imagined story links up to others. So in the story of how the dog person Joan (or dJoan) inspires the Underpeaole to love their oppressors, and shame them into seeing them as fellow beings, we get the seeds of future tales. There are computers imprinted with the memories and personality of dead people, machines which are gods, planets defended by psychopathic mink and many more. If you enjoy the playfulness of a mind steeped in many cultures and don't object to some appalling pop lyrics, this is one to try.
