Welcome, Walker and Mom. (What's your name?

)
The past few days his blood sugar has been getting higher and higher. Vet told me to increase his insulin to 3 units. However the last time I did he started hiding behind the dryer and isolating in general. Not sure what is going on.
We often see cats here who have been prescribed too much insulin to start with, or whose doses have been increased too quickly. From what little information you have already given I think you are right to be concerned about Walker.
I am worried that he might already be on too high a dose of insulin. I would be very worried about increasing his dose again. Too much insulin can look like too little insulin because the liver works overtime to release glucose into the bloodstream to compensate for the excessive amount of 'foreign' insulin being injected into the body. Adding more insulin to an already too-high dose will just keep driving numbers up or, worse, could trigger a hypo episode. I'm particularly concerned about your vet's instruction to give 4 units of insulin at night because many cats' blood glucose levels go lower at night. If it was my cat, I would not increase the dose till I knew
exactly what was going on with my cat's blood glucose levels.
Your description of Walker's hiding behaviour could be his way of letting you know that the insulin is making him feel lousy. (For information, my Saoirse started behaving very similarly when she was being treated with Caninsulin, another quite harsh insulin. She did
much better and was much happier and healthier when on Lantus.) This could either be due to him being constantly in high numbers or else possibly his blood glucose levels being on a bit of a rollercoaster due to the insulin. (Need more data to determine what's actually happening.)
History:
We don't have much in the way of data from you yet. Could you answer some questions for us, please?
- What was the starting dose of Novolin N and how did Walker behave at that dose? What were his BG numbers like then?
- By how much did your vet increase the dose and when? What changes did you notice in Walker (playfulness, alertness, how much he was eating, drinking and peeing)?
- What dose was he on when he was more playful and energetic? What were his numbers like then?
Food:
His weight is a little low. He is at 10.15 lbs. Vet recommends that he be 12lbs. Is there any food that can be left out that is low in carbs in case his blood sugar drops while I am away at work?
Is it Fancy Feast Mixed Grill that you're feeding? Also, is the Royal Canin Urinary s/o the dry food or the canned?
Whatever you do,
until such time as Walker's insulin dosing is sorted out DO NOT CHANGE HIS DIET UNDER ANY CIRCUMSTANCES. The dose needs to be sorted out urgently.
Since Walker is underweight at the moment and he's at high numbers he's not able to use the nutrients in the food he's eating properly. He needs extra food. While you're sorting out Walker's proper insulin needs I would recommend in the strongest terms that you
leave food out for him at all times, doubly so while there is a question mark over whether he's getting too much insulin at the moment.
