okay, updating in case anyone else has this happen to their bun as well. The vet said that Fizz took her shot about noon without any problem and she was fine when we got home, nibbling on greens a bit. About two or three hours in though she started to get very lethargic and she stopped eating. I gave it a few hours in case but she didn't perk back up or start eating either. When I say lethargic I mean - she's hop two steps and have to lay down. And it wasn't the determined bun hops we're used to, these were very tentative. She wouldn't even touch her favorite papaya treats. I called the vet and they said this sometimes happened and to put her on meds and syringe feed her. So I started her on .25cc of Cisapride every twelve hours and 50cc of critical care every six to eight hours. It was pretty alarming how listless she was and she didn't even fight the syringe feeding which is completely unlike her. Her stomach was pretty quiet too instead of the usual gurgles. Her ears got cool a couple of times so I was pretty intent on keeping her warm, something she wasn't down with. It was a pretty rough night for me and I didn't get a lot of sleep. The next day she was a bit better, had a little more energy, still didn't fight her feeding but did hop off several times during it. Shortly after her 3pm feeding the second day she started to nibble on food on her own and pretty soon she was going to town on her greens and demanding treats again. By last night she'd gone through two bushels of parsley and was eating hay so I gave her a last dose of the Cisapride about 6 in the evening and didn't syringe feed her. She ate and dozed all night long and today she's back to her usual self, gurgly stomach, busybody energy, demands for treats and all.
Now there was some seriously gnarly poop at the beginning. The first one looked like about five smooth cecotropes all linked together and it smelled terrible even for cecotropes. We had at least two more magnificently sized piles of something similar before things started to get back to normal. She's pooping fine now; they're small in size but a lot more than usual so I figure its just her body settling down and getting back into the routine. I gave her some bene-bac just to be on the safe side.
And that's my vax story. I'd been warned that she might get a lump in the shot area for a few days (she didn't) but no one mentioned going off her feed until after they'd given her the shot and no one mentioned the lethargy at all. Things seem pretty much back to normal but I figured I'd add this in case anyone else had it throw their bun for a loop the way it did Fizz. For us it was about a two day recovery.
