My cat Ravan was diagnosed July 2018 with stage 2 Kidney disease. He's 17 yrs 6 months old.He also has diabetes & high blood pressure & began having seizures October 2018.
He's doing well. I give him something called Calcitriol & low Phosphorus food & his kidney Values have improved. Here's info about Calcitriol
http://www.zzcat.com/CRF/calcitriol/calcitriol_docs.htm I order it from a Compounding Pharmacy,you need a Vets prescription.
It seems not many vets are familiar with using Calcitriol & some think you don't give it until the disease progresses but if you read the information they clearly advise to
start as soon as possible . It's a liquid & Ravan gets it 2 times a week.
Apparently it's helping the Kidney disease so I'll continue to use it . His last labs showed his values are better than from a month ago!
The Food chart by Dr Pierson tells you the carbs & Phosphorus.I try to keep the Phos. below 200. It's not necessary to feed "special" food for Kidney disease. Vets advise low protein but that's not really good for cats. Ravan eats pretty much what ever he likes. He was raised on a raw meat diet & now occasionally eats premium canned food also. NO fish & no dry food. There's a powder called Aluminum Hydroxide that you can add a pinch to a spoon of water & mix it in the food . It helps to lower the Phos. I also have a few bowls of distilled water that I add a pinch of backing soda to to make it a bit alkaline, it's good for his kidneys.
I read your kitty was shaking? It might be a small seizure. I give Ravan 1 or 2 drops a day of Allevet or Charlottes Web CBD oil. These are the only 2 brands I'll use. Cornell University did a study & they are the Brands they recommend. The CBD Oil does help Ravan . He had a seizure again when I stopped giving him the CBD Oil. CBD is also good for pain & increases his appetite. (I try not to give any pharmaceuticals unless absolutely needed.)
Here a good web site for Kidney disease info

The more informed you are the better to help your Kitty. You can check out Ravan's Spread Sheet & his Labs. If you have any questions I'd be happy to try to help.
Garfield has diabetes for a very long time. You must love him very much & take great care of him!

I don't give dosing advice or interpret Lab results. There are people here that are very good at that that can advise you.
