So she's hospitalized on fluids overnight.

she's never been hospitalized. Right now all we know is that she has a positive snap cPLi test but it was after hours so in the morning she's going to have more blood taken to find out her cPLi level and we will also do xrays +/- ultrasound to make sure there's no underlying cause.
She's had both metacam and tramadol long term in the past with no issues. We sent a geriatric blood panel out two weeks ago and it came back perfect.
We know she doesn't do well with anesthetics so is that a contributing factor? We aren't sure.
It does mean that she can't be on her j/d food anymore and I'll need to find a safe way to supplement her fatty acids and glucosamine.
My poor old lady. I'm such a dramatic worry-wart when it comes to her but I can't help but feel like it can't "just" be pancreatitis...
Thanks everyone for your kindness.
