I don't know which antibiotic Aroara is on but you could ask your vet if they could give her a Convenia injection. It is a rather new injectable antibiotic made by Pfizer that is similar to Clavamox. It's one shot and equivalent to 2 weeks of giving pills two times a day. Tiger has had it quite a few times and I think Freedom has used it on her pets as well.
Your vet may not have it just like mine didn't when I asked about it but they said they could call a nearby clinic and 'borrow' some which they did. They were really impressed with it and ordered some in and are administering it to lots of patients now. I guess it would depend on the type of antibiotic he wants her to be on. Here is a link to the Convenia website.

If that's not possible, maybe you could give her a dose on the morning that you leave and on the night you return so there would only be 4 doses missing inbetween (if she gets them 2 x per day). And hopefully by then she will be willing to take a pill in a pill pocket that your pet sitter could give? I break up the pills in half and give them in two pill pockets so there's no chance of them biting down on the pill.

Glad to hear that her fever is down and that she is eating a little bit! That is awesome!!!
