OK.  Imagine you're an alien paleontologist, excavating the former site of Las
Vegas, millions of years from now.  You have already dug up a bunch of house
cats; then you start excavating Siegfried and Roy's house.  You find a baby
tiger but, for whatever reason, no adults.  The tiger cub is clearly related to
the house cats, and shows lots of obviously juvenile characters, but is too big
to be a juvenile house cat.

Please tell us why we should assume that the tiger cub is a neotenic adult
rather than a juvenile of a species related to but larger than a house cat.
