I've already booked a vets appointment but I wanted to get your guys help calming me down and telling me what this might be. Pippin seems to have lots of jelly-like crystals in his urine- they are orange, soft, and a few millimetres wide, dotted all over the floor, along with wet urine. I looked at his little area, to see if it all looked okay, and on one side of his urethra there looks like a black swelling, which opens. It's really weird and I can't see one on the other side. He has had no changes in diet, or been on medication for anything. He is eating, drinking, pooping fine. He is happy and well, washing and binkying. What could that all be about??
