I think there was a miscommunication in the thread above. Bam was saying that motility meds shouldn’t be used if there is a blockage, but they are used for stasis. Sometimes a combination of multiple meds is needed . The two main motility meds are metaclopromide and cisapride, they affect different parts of the gut. It sounds like your bun is getting treatment, but may need dif meds or just more time and gentle supportive nursing care. I would resist the urge to do aggressive tests or treatments, especially if the vet is not 100% rabbit savvy. Sometimes the treatment is perfect but the bun needs more time to respond.
Encouraging movement in cases like this can help too. One of my bridge buns Bun Jovi was at the vets with stasis and he wouldn’t poop for two days until they put him in one of the exam rooms to run around. Then he finally pooped all over the place!
