But did any of your cats stop grooming and purring, but then start again once you got them regulated?
Yes, oh yes! In fact, when I took Wink in from the shelter to foster, he started to pull and tug at his matted clumps of fur on his hindquarters, 2 days after I took him in. I couldn't get those big tangled clumps out fast enough for him. Did very short sessions with a metal toothed comb, for long haired cats, teasing out those clumps and cutting out others.
Slicker brush to help with other spots.
Purring took a bit longer. He was in absolutely horrible shape when I got him from the cat shelter.
Growing his magnificent long hair back took months. He had gigantic nickel and dime sized patches of dandruff, and his hair was very thin and patchy. Shelter did a bad job taking care of diabetic cats like him.
Diabetic neuropathy took time to heal too, but that was completely resolved.
Hope. Always remember that there is hope for you Kyle and your kitty Vlad.
While you are still on the Vetsulin, and waiting for the Basaglar to arrive, you might want to up the dose of Vetsulin to 4.25U. The 4U right now isn't cutting it for Vlad. And hold the dose steady for 6 cycles minimum, unless Vlad drops <90 mg/dL. Changing the dose every day, cycle to cycle isn't helping Vlad to get lower BG numbers and feel better.
Consistency. Insulins like consistency.
I don't see any indication on Vlad's SS that says you should have been adjusting the dose from that 4U you were giving back on 4/13. Why the changes from 4U to 3.4U to 3.6U?
Whatever you are doing with the insulin dosing makes no sense to me. Would you explain a bit please? I'm perplexed.
