We have a diabetic cat who gets 1.5 units of Glargine at 10:00am and
again at 10:00pm. At the 10:00pm shot on June 7, we checked his sugar
and unexpectedly got a "High" reading from the meter, meaning his
sugar was too high to measure. We bumped that shot to 2 units.

We went back to 1.5 units the following morning and he was fine the
8th and the 9th. Unfortunately, I don't recall what his meter readings
were. The morning of the 10th I found him unconscious and checked his
sugar to find it at 20. We rushed him to the vet, who gave him an hour
to live, but he rallied and is back to as normal as a 15-year-old
diabetic cat can be.

The vet is saying that it was the 2-unit shot given on the 7th that
caused the crash. I disagree. I'm an insulin-dependent diabetic myself
and I simply don't believe that Glargine, with a cycle time of 12
hours, could cause such a reaction more than 48 hours later.

Any thoughts on the matter?
