We had Louis happily using all our cat boxes, and not peeing on doors.

My son's girlfriend has come to live with us, and he made one spray on
the original site (front closet door), but otherwise calmed down.

Then my mother-in-law came to visit, and we went from a 3-person
household (me, my wife and my son) to a 5-person household in a week.
On top of it, I discovered that our neighbor's cat is not spayed
(visited her outside and saw visible in-heat bleeding) AND there's a
new cat in the neighborhood roaming through our front yard. As a
kicker, we moved furniture and repainted two rooms in our house.

This was obviously too much for Mr Skittery Bengal. Front closet door:
SPLASH, den door: SPLASH, upstairs door: SPLASH, kitchen floor: GUSH
GUSH SPLASH.. KABOOM!! I seriously entertained, for the first time,
fitting him for stud pants..

We cleaned all the sites (using an enzyme cleaner and "Anti-Icky-Poo"
- an incredible product), my mother in law left, the paint dried, and
it's been way too hot to avoid the AC with open windows. One week and
counting, and he's not marked a single site.

Of course, being unable to question the offender, all us armchair cat
behavioralists are left with is circumstantial evidence, but this
seems pretty compelling.

The cystitis is still a possibility here, being stress related. I'm
thinking of taking Megan's advice and giving Louis Glucosamine
Chondroitin.

At least I'm pretty sure we can plan that when there are big changes,
he's gonna want to mark the whole damn house again.

I wish there was a really, really nice kennel we could send him to if
we need to do more redecorating, or need to leave for a few days.

Nonetheless, though I'm swayed away from supporting purebred breeders
after chatting in this group, Louis is the most amazing and curious
little kitty I've ever lived with. He is totally worth the effort
here. If we hadn't bought him, there's no telling what rich peeps
would be getting ready to eject their trophy-cat to a shelter.
