This is just a quick question about porphyrin. I know more or less about causes and what it means. But nowhere could I find information on how quickly it should form. Here's why I'm asking. Yesterday I held Baloo inside my jacket, I petted him, he bruxed and boggled as usual. Then he hid his head inside my jacket for about 5 seconds, and when he showed up again, there was a red circle around his eye, and a little of porphyrin around birth nostrils. I was amazed at how rapidly it excreted! It's that how it happens?
