Did the vet send the stone or crystal to a lab to know what it was?

It was crystals .I believe it was a struvite - hence the struvite-
dissolution diet ?

I agree that it doesn't seem right to give a healthy cat S/D. Neither
seems to fancy the dry S/D that is left out, anyway. The only thing
the vet said was that it was OK for the healthy cat to eat S/D as long
as he did not have heart or kidney problems (which he doesn't).

This very is interesting. Science Diet´s main marketing strategy is to
scare people about the level of phosphorus in other foods because the
cat may be in the early stages of kidney disease and this "excess
phosphorus," according to them, will add to kidney damage. So how come
is it ok to feed S/D if S/D should not be fed to a cat with kidney
problems? What if the cat *is* in the early stages of kidney disease?
How contradictory!

I think you are better off getting him on a canned diet of whatever
brand you feel is best for him than any dry food. An acidified dry
diet may result in calcium oxalate stones down the road and this would
be harder to deal with. If he is made to ingest sufficient amounts of
water, that will better prevent uroliths of any kind.
