Piglet seems better, although she does not want to take her medicine and is all claws and teeth and unhappiness. I got her to take her pain medicine (what, most people love the stuff) by hiding it in her stinky wet food. I have not been able to get the antibiotics down her throat, but I will try again soon.
She still smells like whatever pet wipes the vets used on her; I presume they used wipes because I would think she would not smell vaguely floral after her evening away from home.
She clearly has an infection of some sort, but it is unclear what until the cultures are analyzed. Oddly there were no bacteria in her urine. But there were no crystals or stones present. Although those could be hiding out from manual examination and xray.
I am happy she is home!
