Need more advice from those with cats with crystal problems

[Moesha]

Morgan does have crystals, but I am not sure which kind. I didn't get to talk to the vet because I had to take my car in to be serviced and was there ALL DAY LONG and still have to go back! But that's a story for a different thread. I did talk to the vet briefly on the phone. He said Morgan's blood work was all very good. He is changing his food for 30 days then we'll recheck things, like his sugar level. I'm not sure what food he's getting, but I think it is Hills. My mom picked Morgan and the food up for me, and I haven't seen it yet. Believe me, I'm very strict with Morgan's food. He is strictly rationed with what and how much he eats. That's what I have had to do to make sure his sugar is regulated and how we got off the insulin shots in the first place. I'll discuss this in detail with the vet when I talk with him in the morning. Morgan couldn't eat the canned food, he kept throwing it up. He does that with most canned food, there are only a few brands and flavors that he can eat. I do have to watch and make sure he urinates daily. The vet said that he would hold it and then pee a huge amount once a day. But that he was peeing enough when he did that. It may have been because he was in a strange place with a different litter box. I'll keep an eye on him here though! I just love watching the litter box.

ETA: His food is Hills S/D. I went to see the nutritional chart at the diabetes website. They say about this food "S/D (short-term use only!!!)". Does anyone have any experience with S/D?

I think I may have figured out the answer to my previous post. I'm mostly posting this here incase someone comes later searching this topic. It seems that the s/d is used on a short term basis to dissolve the crystals, then usually a switch is made to a different kind of food like the c/d to prevent their return.

I talked to the vet today, and he wants Morgan on the s/d for 4 weeks or so. He said that I should be able to tell that he's doing much better then. If he seems ok, I don't need to bring him back in but should switch his food back to the DM food for his diabetes. I'm not sure how this will work since it won't really be doing anything for preventing the return of more crystals. I'm going to see how his diabetic symptoms seem then, and I may then switch to the EVO food that Storm eats. The vet said he isn't concerned about Morgan's sugar levels. They were very good. But of course I was strictly watching his diet. I'm a little uneasy about all of this, but will wait until the 4 weeks of the s/d food is over and then make a decision. So for I've been digging in the litter box for treasures all day. Morgan has peed adaquate amounts 4 times today. YaY! He did go and have some sprinkles one time this morning, but all the other times were small clumps. Because of the diabetes, I'm used to him peeing larger amounts but am happy with 4 moderate clumps.

Yes, that's usually the way it goes, it's the same here with my Luna. But even though she's on a low magnesium diet (like in c/d), the struvite crystals often return, so I always have to watch her closely, and whenever she starts peeing outside her box, I need to have her urine checked and usually, it would show new crystals.

There are some supplements for kitties with struvite problems, like cranberry products. It's important to keep the pH value in their bladder acidic. However, this goes only for struvite crystals.
