I agree with A&B, did you see a rabbit savvy or a regular dog and cat vet? It can really change how treatment is done and the likely hood of survining stasis. And that she needs to be on probiotics. Trust me, I know how scary it is with stasis, I lost one last week to it so we are here for you.
The vet should have done X-rays, blood tests to really see if there isn’t or isn’t a blockage and how the organs are working. Then if no blockages, start on gut moltility drugs, she needs sub q fluids no matter if a blockage or not,until she is back to normal as if she isn’t eating or drinking a lot, she will become very dehydrated fast as they actually consume more water than a big dog! Being dehydrated can cause the gi tract to pull water from other organs and dehydrate them. And then of course pain meds as gi stasis is very very painful, and gas drops. Force feeding of critical care should be done if she will not eat her daily amount on her own.
Also, if she might have some dry poops in her cecum from not eating and being dehydrated, she should be syringe fed water so the poops inside can stay hydrated until her gut starts back up.
Just as an FYI, stasis is a symptom of a larger issue. So that could be a bad gut that doesn’t function properly, bad teeth( did the vet check her molars for Spurs?) not eating enough fiber to keep her gut moving or dehydration could cause issues and therefore stasis is the symptom of it.
I know what I said might scare you, anyone with stasis knows how much of a snow ball it is if the bun isn’t treated right. All of my buns have made it through it with intensive care besides my last one but he had major health complications prior.
