What is mounted around General Zaroff's dining room in "The Most Dangerous Game"? why does the author mentions this detail

In "The Most Dangerous Game," while there is a "medieval magnificence" to the dining room with its oaken panels and high ceiling and expansive table, there are innumerable animals, stuffed, mounted on the walls. These animals are perfect specimens, more perfect than Rainsford had ever seen.  "At the great table the general was sitting alone"--alone with  his jaded pleasures.  Bored with this magnificence, the general seeks prey more "magnificent" than what he has caught.  It is during their dinner that Zaroff reveals to  Rainsford that his "game" is chasing men as prey.
