Hi all I’m new to this board and not sure if I’m even posting in the right place but I need help. My senior kitty girl, Lickety Split, is 17 1/2 and recently diagnosed on February 28th. To understand more I need to give her backstory. She has mammary carcinoma that has been controlled with chemotherapeutic drugs. Her oncologist said she isn’t an surgery candidate because of her age and heart murmur but would most likely outlive her cancer. She was doing great with perfect bloodwork up until diagnosis. Unfortunately I had to board her for 5 days with my vet while recovering from surgery because she is difficult to medicate and on lots of meds for cancer, heart and arthritis. I have extreme guilt because I know that the stress caused her downward spiral. At her oncologist checkup on Feb 28 she had reading over 650 and I was told she’s diabetic. She also had elevated creatinine. My vet didn’t have insulin and told me to call around and find vetcillin. I could only fine ProZinc so she was put on that at one unit twice a day along with fluids for her kidneys. Three days later she was rechecked and still over 500. My vet increased to 2 units twice a day. Four days after that she was still over 500 and increased to 3 units twice a day. Four days later she was having trouble walking and standing up. She was at 700. My vet told me to increase to 4 units twice a day. Two days later I brought her back in and she was still over 500. My vet changed to Novolin N 3 units twice a day. I was nervous because I heard this insulin isn’t great for cats and it was so cheap. I heard that it is harsh as well. Her levels were getting down around 250 and sometimes still around 500. Then two days ago she was over 600 and today is back to being unsteady when walking. My vet increased to 4 units twice a day. I’m so upset thinking all of these changes so quick has compromised her. She’s also urinating a lot and was put on Clavamox in case of infection. She’s eating and drinking ok. It’s also hard to know how much is neuropathy from her levels and how much from her severe arthritis. I’m wondering if I need to go to another vet as her oncologist is the one dosing her. Times are tough right now as I’m not working due to current events. She eating some FF pate as well as some on her brothers low phosphorus renal foods. What insulin is best? What is normal dosing increases? How often do I need to test? I was using AlphaTrak but just switched to ReliOn classic for cost purposes. I’m so lost and feel like it’s making it worse on her. Thanks for reading.
