Is there any reason you are not getting a test before you give the insulin? Given some of the very low cycles you have had recently, this makes me very worried for Webster, ideally you want to check BG before giving insulin to make sure it is safe to shoot, you are also holding on to doses a little longer than is safe, when you get a drop into the 30's that's an immediate full reduction for any cat longterm or newly diagnosed, when following TR, ie a 0.25u reduction, taking smaller reductions and not taking them when they are earned can really land you in hot water. I would have probably also thought about taking a full reduction after a drop into the 20's
I know he is seeing some higher numbers now, but that just makes me think he is bouncing of some lows that you are not catching.
Are you using a human meter?
I looked back at previous thread and I see you were trying to skinny the dose as he doesn't hold reductions well, but as
@julie & punkin (ga) said in the
thread of 3/4 you really don't want to combine both methods, ie holding the dose for 3 drops under 50 (NB a drop under 40 is an immediate reduction), and then only shaving the dose for a reduction, doing both is a little too aggressive and may be why you have been having to deal with numbers in the 20's
I agree with
@Squalliesmom regardless of what is in the water it sounds like Webster is not well at all, so a visit to the vets might be advisable.
If he's not feeling well, it might be an idea to check for ketones too.
