No! Of course not! That's exactly what the forum is for, Sue.
There are several possible reasons for a low preshot number with Caninsulin (Vetsulin), including:
The cat producing some insulin of its own:
Patterns you might typically see here are
either that the BG drops into a good range, and then 'surfs' there for the rest of the cycle;
OR, that the BG drops throughout the entire cycle. The latter could also be caused by 'bouncing'.
Bouncing:
When a cat's blood glucose drops too low or too fast for the body's comfort, the body can release stored glucose to raise the BG level. It can also release counter-regulatory hormones, the purpose of which is to try to
keep the BG high. Once the effect of that wears off the BG will drop again. And sometimes it will drop, and drop, and drop throughout an entire 12 hour cycle, or even longer.
If bouncing becomes a
pattern you'd typically see high, 'flat' numbers, interspersed with low numbers. So, if this pattern is observed on a cat's SS bouncing should be considered as a
possibility.
Possible 'remedies' for bouncing depend on the reasons why the bouncing is happening:
If the BG is dropping
too fast (but the insulin dose itself seems sound), giving a second meal an hour or hour and a half into the cycle may help to slow down the rate at which the BG drops. (Manipulating the cycle with food is called 'steering the curve'.)
If the BG is dropping too low (ie. potentially into hypo range), then the insulin dose needs to be
reduced.
If the BG is staying at safe levels but is just dropping too low for the cats comfort level, there are a couple of options:
- It's possible that reducing the dose a little may help to even out the cycle by keeping the BG above whatever level is triggering the bounce. Some folks try to get their cats used to the BG level just above the trigger point, and then gradually take the cat's BG down a bit lower. Does this work? Sometimes. Sometimes not.
- Alternatively, you can just continue with the dose and hope that the cat gets used to the lower numbers and stops bouncing. Does this work? Sometimes. Sometimes not.
Some cats are just more prone to bouncing than others; and some will even bounce all the way to remission...
