~l~ that doesn't help. I have always associated books by title and or author only. and have read on average 200 books a year, some years closer to 1000 way to large a database of books to sift through for the title. the actual phrasing of "martian flat cat" strikes me as Heinleinian in nature, though it could also be Tubb, Smith or Asimov as easily. Tubb didn't run to fauna in his works, nor did Smith, but both Heinlein and Asimov included the Fauna.......not Norton, definately not Mcaffery..... nope I'm stumped.
