Honey had mucoid enteropathy apparently it presents differently in adult rabbits, as there was no mucous. The only way to tell that they have it is to perform surgery to take a biopsy from the stomach. So i couldn't have known but having just googled it, stress is a major factor, so I'm now wondering whether she didn't have it before, but the stress of being at the vets brought it on? I suppose I'll never know.
