I'm trying to identify a sci-fi book I read in my youth in 1970s.
Key plot points:
- It was a saga of the far future where humanity was blended with many different animal types, so characters were partly like lions, tigers etc.
- I think they were also clones, and their names included numbers to show what generation they were.
- The main protagonist was called something like 'adam 25' and he was the prince of a royal family.
Timeline and other relevant info
I read this at some point from early to mid 1970s, alongside things like 'Shadow of heaven' and 'Eyes of the overworld'.
