Okay, water. Even if she hardly drinks any, if you add it to food.....there you are. That's plenty to create and perpetuate a problem.
Now..... there is a relationship between allergy, infections and pH. For one thing, allergy can affect pH, and allergy can also cause infections. Especially in the urinary tract. On the other hand a pH problem can affect reactions to everything. Food, water, etc. It's how the body deals with things (different for every individual) and there is nothing we can do about that except adjust our diet (and our cats' diet) to avoid problems.
(Allergy can also cause nasty, terribly painful bladder inflammation without bacteria or crystals.)
Having to feed acidified food is not normal. It's okay as a temporary solution to prevent more serious trouble, but the reason for the need of acidified food must be found and corrected. With water that has the right pH and mineral content for a cat and food that doesn't cause reactions that raise the pH, acidified food is not necessary. Trust me on this.
Distilled water.

| yes, I mean bacterial UTIs. When she is off the c/d entirely, the crystals come back full force, causing irritation and pain in her urinary tract, so she washes almost continuously, which brings on the bacterial infection. |
Clearly a pH - food ingredient problem. Water can have a role as well.

Only because it helps you avoid looking for the root cause of the problems and making the necessary changes that will make it possible to feed a normal diet.

| Every 2 years or so I start to fret about her lack of water intake, even though her blood work is always fine. |
The lack of water intake on a dry food diet will have an effect on the kidneys as she ages, even if there is no immediately noticeable effect right now. So I completely understand why you get worried, but again, trust me on this, watering up canned food is not the answer. Canned food that is high in animal protein and has no other ingredients that will raise the pH, has a naturally, mildly acidifying effect that keeps the pH low. Added water actually has an alkalinizing effect. And if it's the wrong kind of water on top of it, the good intentions turn into a trap with bad results.

| She loves the c/d kibble and never complains or acts unhappy with her food. It's my own projecting, I know, that makes me want her to have canned food, because I know she really does love it (except the canned c/d of course) and I want her to be happy. |
No, you know that she would need canned food and you're absolutely right about wanting her to have canned. She loves the dry c/d. Well, kids love candy. But that's no reason to let them have it instead of good, healthy food. You want what's best for her, you're just having trouble getting there. But you will.

| I am interested in what foods you have in mind |
Actually, I wasn't thinking of trying to make any suggestions. But it would be a good starting point if you could check the ingredients in the foods your other kitties are eating and try to see which ones likely made Mazy sick. Ingredients besides the protein sources and added supplements that is.
If you look for new foods for her, they don't have to be expensive and "high-quality" to keep her healthy. They just have to produce the right low pH and any ordinary no grain/no vegetable food can do that. Also, the good thing about canned food is that cats don't need additional water and normally they don't even drink until their kidneys start aging and become less efficient. At that point one starts seeing a cat at the water bowl now and then..... and then, as time goes by, more often. The interesting thing is that, even when they start drinking on canned food, the kidney values are still perfect and they can hold steady for several more years. The canned food continues to protect the kidneys.
I'm wondering about something. Is she getting any treats? Cat treats and people foods maybe as a treat?
