My previous house bunny ( mr dk bones - now in bunny heaven) had this regular. All of a sudden, I am so sorry, I am sure your bun will be fine and dandy in no time! It's awful isn't it when you have to leave them at the vets. My vet said that he had IBS along with neglect at birth ( we stole him from a rubbish owner - long story) this is what made his gi statis an ongoing problem! I am sure your bun will be fine! Let me know how your bun gets on.:wave:
