Boy, this has become kind of an internet version of a kid in a well, but I’ve had so much interest and well wishes in the situation that I’ll provide an update.
I just got a call from the vet, and the short answer is that she doesn’t know what’s going on, except that the red cell count is down to ten percent, which is below the level at which they normally transfuse.
There’s no fever, and in fact she’s hypothermic, so they’re keeping blankets on her. No problems with kidney or liver function. She’s wondering if it’s some kind of parasite, but won’t know until they do an outside lab test. She’ll probably need blood, and at least an overnight stay tonite, neither of which are available at her current facility, so I’ll have to move her (or have them do it).
That’s all she knows for now.
