Here is part of one of your posts from over on Facebook, so we have a little bit of background info.
"Hello! Apologies in advance for the long read.
The photo is Kit cat. She was diagnosed Saturday with diabetes. She had gone to the vet in October to get her teeth cleaned, and I also changed her food at about the same time (she wasn't liking what she was eating - taste of the wild dry food). I switched her to a combination of American Journey and Wellness Core. I did a slow switch (well, as slow as one can do when one's cat is picking out the new and only eating it). Not long after the switch I noticed she was peeing a lot more often, in big clumps, and was drinking far more water, and it felt like she'd lost weight. I found out her brother, who my friend brookE has, had the same symptoms, and was diagnosed with diabetes.
Kit went to the vet on Friday - her weight had gone from 13.2 in October to 12.1, and was diagnosed on Saturday with blood glucose levels above 400. The vet (a guest vet, my regular vet is gone until after the first of the year) suggested the prescription dry food. She won't be starting insulin until after the vet reopens on the 3rd of January and my regular vet is back.
I started out planning to use the prescription food, because quite frankly I was freaking out a bit and it was kind of a knee jerk reaction, but after more conversation with brookE, and looking at information readily supplied by this amazing group, switched her over to Fancy Feast and Friskies. On Sunday and Monday she had about 1/4 cup of dry food each day and the rest was wet food. She had her last dry food yesterday morning, about an 1/8 of a cup (I was going to do a slow transition to all wet) and then I decided to just stop the dry. She has only been on FF or Friskies since then. I do mix extra water into her wet food, because she likes it better (she was occasionally getting FF prior to all of this).
I also picked up supplies to begin home testing - she's a nervous nelly, so I'm working up to actually testing her, and have been spending the last few days rubbing her ears, and giving her lovies and treats on the counter where she will get tested (I have a bunch of freeze dried chicken/salmon/sirloin because she's been eating that on her dry food for over 10 years). I'm hoping to get her first test in tomorrow.
So - the interesting thing. Before yesterday, she had been peeing 5 or 6 large clumps every day, and drinking a lot of water. Yesterday, having eaten a fair amount of wet food over the previous couple of days, she only peed a couple of times and only drank water a couple of times. Today, she hasn't really drank her water, and has peed a couple of times, and the clumps are smaller. I'm hoping this is a good thing.
So that's where we are. I still have a bunch of reading to do, and I am so incredibly thankful and amazed at all of the information y'all have. I'm sure also sure I'll have so many questions."
p.s. What a beautiful torti! With the 'tude.
