I heard from the vet today and he said that River's kidney results were normal, so it's not kidney failure! Due to her globulin levels being increased, he suspects she has an infection (UTI) and is prescribing her Baytril, which I'll pick up tomorrow.
He also wanted to ensure she stays hydrated, so is going to show me and big human how to give subcutaneous fluids (it's a two person job). This will save her the stress of a car trip and vet visit.
Her calcium levels were a bit high, though that is most likely due to diet (alfalfa is in the critical care mix as well as some of the hay cubes since she doesn't really try to eat actual hay anymore). He said at her age, we pick our battles and it'll just be something to keep tabs on--I'll try to increase the timothy pellet portion of her paste mix and the bunny Ensure mix.
