Hello and welcome.
We've had many cats on Zobaline, without in increasing blood sugar. Perhaps if you can let us see your blood sugar test numbers, we can help you find another reason his numbers are going up. It's possible what you were seeing is something we call a bounce. This definition is from the New to the Group Sticky Note.
Bouncing - Bouncing is simply a natural reaction to what the cat's system perceives as a BG value that is "too low". "Too low" is relative. If a cat is used to BGs in the 200's, 300's, or higher for a long time, then even a BG that drops to 150 can trigger a "bounce". Bouncing can also be triggered if the blood glucose drops too low and/or too fast.The pancreas, then the liver, release glucogon, glycogen and counter-regulatory hormones. The end result is a dumping of "sugar" into the bloodstream to save the cat from going hypoglycemic from a perceived low. The action is often referred to as "liver panic" or "panicky liver". *Usually*, a bounce will clear kitty's system within 3 days (6 cycles).
Make sure you read all those sticky notes too. If you'd like with figuring out dosing, we use a common spreadsheet format here. Here are the instructions for the spreadsheet.
