Hi everyone, I am new to posting here but have become familiar with this site on and off over the last year since my boy Otto was first diagnosed. Otto's become hard to regulate so I think it's time I jump on the boards here and see if anyone has any ideas. He was a "honeymooner" and went OTJ a few months after his diagnosis a year ago. At the same time of the FD diagnosis, he was diagnosed with Hyperthyroidism so I started giving him Methimazole in addition to 1U Lantus 2x/day. Unfortunately at his spring check-up, his bloodwork showed that the Hyperthyroid was not under control anymore, and neither was his blood sugar. So long, remission! Since then, it has been a frustrating ride trying to regulate him, and his insulin dose is now up to 4 U. In the fall, I did slowly switch him off Fancy Feast Classics to accommodate my other cat's IBD issues. Twiggy is allergic Fancy Feast Classics, but naturally she loves it and is constantly lurking to steal some when my back is turned. I thought I read that Nature's Instinct limited ingredient food was low-carb, so I thought it would make life easier to feed them the same food -- and Twiggy was doing great on the Instinct brand. But recently I made the connection that Otto's BS numbers creeped even higher right around the time I took him off FF. Nature's Instinct carbs are slightly high -- 10-11%. My vet said it should be below 7%, so back to FF it is. We were about to switch off Lantus but my vet recommended waiting to see if going back to FF helped before making the switch, and it seems to be working -- his numbers are more consistent than they've been in 6 months. They're still not dropping into the 100s regularly, but the nadir is more consistent. But morning numbers are very high still. I'm not sure if this is bouncing, or if he really should be on an even higher dose. I will post this in the Lantus forum, but wanted to include all this background in case anyone has had a similar experience... Anyway, Otto is a cuddly, clumsy sweetheart and I want to do my best for him. Lately he has been much more lethargic, and the neuropathy and arthritis cannot be pleasant. I don't want him to suffer, but he's still eating and using the litterbox as usual and purring whenever he can get laptime, so I still have hope than things can get better. Hoping to learn as much as I can here so I can help him. Thanks for reading!
