You have to clean it up to avoid infection. I would use biseptine but I have no idea if that's available in your country.
I found that on a specialized website :
"If possible, bite wounds should be flushed with copious amounts of warm, soapy water (unless the wounds are deeper than the skin, in which case you should wait until you can seek professional care). Povidone iodine solution, diluted to iced tea color in warm water, is wonderful for flushing superficial wounds. In a pinch, antiseptic soap and warm water can be used to clean wounds. If you think that your rabbit may be in shock, do not waste precious time cleaning wounds at home."
