Rabbit's Urine Color Is Strange

We have a 2 year old un-neutered dwarf rabbit. We have found her urine to be very dark orange, and lately darker still, almost blood - like. She seems healthy as usual. Could this be blood, and have something to do with her being un-neutered, or is she sick? (Lawrence Monk - United Kingdom)

Rabbit urine varies in color from clear to bright red, and this is not usually a cause for concern unless accompanied by other symptoms, such as straining to urinate or loss of appetite.

Be observant and keep your eyes open for other signs that might indicate a problem. If you are in doubt, or you think you can actually see traces of blood in the urine, please consult your vet.
