My bunny has red color pee?

It is natural to think that something is wriong when a rabbit pees red but it is normal. Most cases of red urine are due to hte presence of a plant pigment called porphyrin.It is completely normal and not a reason to be concerned. There are more cases of red urine during the fall and winter. If the urine does not return to its normal colour ni a couple of days take it to the vet.
