Great job of putting the labs on a tab on your SS. Also some good news for you...yes, Mao appears to have chronic kidney disease but you've caught it at a time that there is a lot you can do to ensure she has a good QOL for a long time.
What I've found to be the priorities in treating CKD are (and not in order of priority as they are all important)
1. Hydration
2. Phosphorus control
3. Anemia control
4. Eating
5. Potassium control
Her BUN and creatinine are elevated indicating the CKD and some dehydration. Usually it is recommended to start daily fluids when the creat is 3.5 so I think you are basically there. Be sure you are taking I to account how much she drinks or you add to her food. It's always best for a cat to get hydration from drinking water or from water you add to food. You should discuss with your vet how much to give but you might want to start with 50-75 mls daily if she weighs less than 10 lbs and 75-100 mls daily if she weighs more than 10 lbs. Again....your vet should guide you but cats do better with less fluids every day than more fluids every other day (which is what some vets recommend). Usually Lactated ringers solution is the best for CKD kitties, in general, but I understand there is a shortage so talk to your vet what he feels is the best. Also....be sure Mao does not have any heart issues. Giving daily fluids to a cat with heart problems can overwhelm the circulatory system and result in congestive heart failure.
Phosphorus control is critical to the way Mao will feel. The renal diets are the best for this but they lack in nutrition. Hi Tor Neo is a little more palatable and it is 9% calories from carbs. The only low P diets are the kidney diets but many low carb diets are better quality and have lower (not low) P. If you don't feed a kidney diet, you want to stick to a canned diet with less than 100 mgP/100 kcal or that is less than 1% P. If she won't eat those foods, you can see about using a binder but the best solution is to try the low or lower phosphorus diets first.
Controlling the anemia is also important. I would start now while she is not anemic. You can give her 1/2 of a Vita Cost methylB12 500 mcg capsule twice/day (bid). She should also have 1/10th of a Jarrows B Right multi B capsule sid. I bought size 3, clear and empty capsules (
www.thrivingpets.com) and made my own capsules .
Number one rule of thumb...she must eat. The Rpyal Canin and Prescritopn Diets are really high in carbs so if you want to use those, you'll have to increase the insulin.
Maos potassium is perfect right now. If that number creeps down, let me know and we will talk about it in your condo.
I have to get to bed...I have to work tomorrow and I was up all night with Gracie. But that's some info for you to start with and I'll post more tomorrow.
The bottom line is...it's not bad and you have the opportunity to try and slow it down. :YMHUG:
