one of my foster buns decided to do that too!! The first vet just stuck her on antibiotics and said she'll be fine.. I wasn't all that impressed as she had a gaping hole in her tummy!! A few days later I'd had enough, and went back to the vet (diffrent one this time) and he was in utter shock, saying it should of been stitched right away (grrr) and as it was only a quick 15 min procedure, I should bring her in the next day and he'd get it done.... poor girl had to wear a buster cone for the next week, much to her utter disgust!!! Though it was very funny watching her trying to have a wash :lol: poor baby!! She's fine now though!! Happy as a lark, and a lot friendlier!!
I'm sure your bun will be just fine!! sending tummy healing vibes!!
