Diagnosed in August after 4 months of feeling just awful and going to the vet for many undiagnosed visits, but that was just the start of not doing right by such a sweet, sweet cat. EVERY piece of equipment we have used on Grrr has completely failed (2 meters, lancing devices, his ears, needles, everything) and now I have to wonder if our Vetsulin is even any good. Nothing works. And our vet is furious that I increased slowly from 2u twice a day to her recommended 3u twice a day, and even though we're now at the 3u, after constructing the spreadsheet, I see little difference from diagnosis with no insulin to today at 6u per day. My cat spends 50% of his life over 450 according to the Libre, and based on Grrr's history, most of that is also over 600, although the Libre will not report over 500 so I cannot be certain. And no, we can't get blood out of his ears, and no, it is not just me that can no longer obtain a sample, it's the whole household- and everyone on here keeps saying he'll bleed more, but the truth is that his ears bled less & less every time to almost zero so we have to depend on a cgm. He also flinches when insulin is given and no one else here reports that either. We do not move the needle around and have decreased to a 31g but it is little comfort to him. It is so sad because he really wants to live and trusts us, and we are trusting people & equipment that have done nothing but fail us repeatedly. What have other owners done when they are already at a dangerous 3u of Vetsulin and it doesn't help? The vet believes that Vetsulin is top-notch for cats and stated last week that my cat has not been on it long enough to work (one month). I don't know about that after reading so many things here. All I do know is this cat doesn't deserve all the bad things that have surrounded him with this disease. I can't take the thought of putting him down, I just can't, and can't take the thought of continuing with completely useless medicine & tools. What do people do?
