I was just talking about this with someone, thought it could be a fun thread. What is the strangest (but not gross!) diagnosis you've seen? Ours was a cow. . . Who became allergic to sunlight when pregnant. Her name was Fronz. We always knew when she was about 21 days pregnant because she'd leave the barn looking norml, come back after a couple of hours COVERED in blisters. Not even just where the sun hit, but all over, even inside her mouth! In the winter it wasn't a big deal, she just lived in the pens. In the summer, we found the one stall in the barn with zero sunlight, and there she stayed. We would let her out in a little fenced off area behind the barn after it got dark. We would just leave the gate open for her on days when he sun would be up before the cows came in and we'd find her hiding in 'her' stall. We kept her for years like that, she eventually died of cancer. It was so strange, and our vet never really had a good explanation for why it happened, or why it was ONLY while pregnant. We also had a black and white cow with a single bright red patch on her side. This is supposed to be genetically impossible. Alas, it was nearly 20 years ago (and now I feel OLD) so we did not really treat this as anything more than a curiosity. Now I wish we had at least taken a picture, or sent and email to Cornell or someplace. What do you guys have?
