A similar thing happened to me only it was more like a scratch, not as deep. I made the mistake of putting betadine on it and literally saw the betadine eat the exposed flesh and the wound got bigger. (no longer using betadine at all for anything) I'm glad you have had better luck with the hydrogen peroxide, still think to be on the safe side it would be best to dilute it but looks like it has worked really well for you. I was able to get butterfly stitches to stick to the rabbit, to hold the wound closed, by using special adhesive that people use to adhere colostomy bags to their skin.
