Update

According to the vet, and following the x-ray, Smokey "probably" has...constipation.

I didn't know constipation could be so painful, she's been so miserable, and for days.

With two sets of blood tests and an x-ray, I'm considerably poorer. She's insured, but there's a 20% co-pay because she's over 15.

I do hope the vet is right. She's going to give her an enema (Smokey won't like that) and a drug to help her move her bowels.

Poor Smokey.
