Sounds scary. That BGL is pretty high. I'm sure they can manage it. Fluids and insulin, I would think? He looks pretty alert.

That pic is not from today but he had been alert all day, eating just fine, no vomiting, which all made me think I was being paranoid and overreacting and we could visit my vet Tuesday, but I’m glad I ordered the glucometer. Though now I wish I’d just brought him in earlier instead of waiting.

They'll get him sorted out. Always a nightmare, though.
