Yes, the glucose is high, but only a tiny bit high, and given that Jacob was completely freaked out yesterday, we're not worrying about that.
His calcium, however, was also high. That could mean that there's a calcium stone in his bladder, which for some reason is not showing crystals. It could also mean cancer. Cancer would explain the weight loss as well.
We have an appointment scheduled for Tuesday for X-Rays and still more bloodwork. We'll know better after that. And I will not be leaving him there; if Jacob's at the vet, I'm gonna be sitting right there beside him. I refuse to let him get as freaked out and terrified as he was yesterday.
