4 year old rabbit

Question
I found some blood under the hutch,leaked from her bedding, which was stained with weak blood and urine. Rabbit seems fine eating ok. Tried to see where blood had come from small bit of dried blood around anal area. Can you help?

Answer
hi lesley she may have caught herself on somehing or it could be hutch burn -this is where her urine goes into her fur and causes a irritation sometimes making it bleed -give the cage a good clean out and wash the area around her anus and see how it goes.
