@Joyfulfeline You PM'ed me this messagage. We ask that people post first in the Feline Health Forum and don't use PM for this sort of question, so I'm starting your own threa.
Last year, the kidney disease in my cat, which was diagnosed first, was stable with a prescription renal diet. Then the cat developed diabetes which the vet tried to manage using insulin while keeping the pet on the renal diet but couldnt get the diabetes under control. With consultation from another vet, the treating vet took the cat off the renal diet which is high in carbohydrates and put her on a prescription diabetic diet with lantus insulin. As a result, at the last vet visit, the blood work showed a worsening of the kidney disease (because the diabetic diet is high in protein) even though the diabetes was under control. At this point, the vet took the cat off the prescription diabetic diet and put her back on the prescription renal diet hoping to stabalize her kidneys and use insulin to treat the diabetes. This cat has had countless at home glucose curves done by me from the pet's ear. Now, because on the new renal diet the blood glucose values are in the 600's, we are starting all over again with the blood glucose curves from the ears. At this point, I am seriously considering getting the freestyle libre 2 with reader. I have a cheap old cell phone and I do not think it is capable of scanning the "disk" to read the glucose levels, that is why I am investing in a scanner. Does anyone on this feline diabetes site have experience with the freestyle libre 2 with reader? If you use freestyle libre 3, does it have a separate reader? Do you have any tips for a new freestyle libre user like me?
