Sorry, no suggestions for the potty problem inside, but for the water bowl...have you tried to use a rabbit water bottle? The ones with the metal tip and ball that hangs upsidedown? I had a friend that bred "squshed faced kitties" and she used the rabbit water bottles. She also had a kitty door built into the wall connected to covered, enclosed dog run with pea (ha ha) gravel and sand. The kitties would "go" outside and she didnt have a litterbox inside.
