Adult Guinea Pig
As part of the continuing saga of my piggies' ill health (all 3 have it, and the main symptom is painful urination with blood etc), my vet has mentioned that this might be a possibility. I have Googled and not come up with much. They are currently on yet more antibiotic - they have had 3 different types now, and it's either extremely persistent, or it isn't caused by a bacteria.
