It wasn't such a crazy idea in light of a society which has
cryogenic freezing of corpses in the hopes that they can
be re-animated one day.

Our society is mad for immortality.  At every stage of
life we are taught that death is the great enemy and
to be avoided at all costs, even when there are clearly
times when death can be a friend.

No wonder someone thought that the wealthy who are
willing to spend ridiculous sums on their immortality
including massive monuments and foundations and
edifices to themselves, as well as some of the
crazier ideas as above, might be willing to do
something equally foolish for their pets.

You'll notice that there is no mention that they
had a lack of clientele.  No, they are turning
away clients, apparently.  The only reason they
are closing their doors is because they can't
make the technology work.  Thank God.
