Actually, some rabbits just always have a little blood in their urine, and it doesn't hurt them in any way. I'd definitely get it checked out, but I had a male Netherland for 11 1/2 years who always had a bit of blood in his urine. The vet ran some bloodwork, and told me that it happened sometimes, and it wasn't hurting him in any way.
