I'd suggest you wait a month after CJ returns to normal
(no meds in his system and eating / drinking normally) and
take a urine sample in for a complete analysis.

The Vet can check for any stones or crystals, do a pH test,
and look for any blood or protine.
A really "complete" urinalysis has to be done by a lab, and is a
lil bit "pricey" - but you might want to consider it.

There are a LOT of articles on the web - many authored by Vets,
that offer information on male cat urinary problems and
dietary suggestions.

I just found This One >>>
"Natural Diet"
that is NOT written by a Vet, and is rather biased against commercial
(dry) foods... Since MANY cats live long, healthy lives eating
nothing other than dry commercial foods, I find her opening paragraph
to be rather "flawed"!
BUT she does hit on some of the Major Cat Health Issues.

When Boots had all his urinary problems, I read a LOT of the
available articles; but didn't put too much faith in any one
"theory" unless I found several Vets who wrote similar articles
or made the same or similar suggestions.

Keeping a *vigilant eye* on CJ when he visits the box is one
of the best ways to spot a problem in the making.
