Smudge came off insulin (Lantus) 6 months ago and has been doing well, with BG spot checks showing her in the range of 6 to 8.6. Last night at bedtime she had diarrhea and vomited twice overnight. Appetite had been good all day. She was a bit fussy with her food today (she normally has a ravenous appetite) but was otherwise okay. She threw up about 2 hours ago, had another episode of diarrhea, and hid under the bed. She came out a few minutes ago to lie on the bed and thats when I checked her BG. Its 32.4. And of course its Christmas Eve. Given her age (16.5) and her other chronic issues (pancreatitis and arthritis), when she came off the insulin back in June, my vet and I discussed that it was now about quality of life for her over quantity, and we would do no more testing if she started to go downhill. But if its just a matter of starting her back on insulin, I can certainly do that as I still have fresh insulin and all the administering and testing supplies. My question is, does this alarming number need emergency attention, or will I be okay to wait until my regular vet is open again on Tuesday? I dont want her to suffer, but I also dont want what could potentially be a $1,000 after-hours emergency vet bill if its avoidable.
