Spawn is pretty much back to her old ornery self. I don't have a thermometer so I have no idea if her fever is completely gone, but it sure feels like it to me. She's been taking her antibiotics quite well, and she LOVES her vitamins that the vet prescribed. Unfortunately she's still on the laxitive (just a little bit daily) and she HATES it. That has become our biggest fight.
She goes back in on Wednesday for a check up, and they'll probably give me more antibiotics (they gave me enough to give her until then), but I think we've got this thing licked whatever it was! YAY! It's such a relief!
