Poor Orion! Martha went through the same thing last year, but I saw her go after a wasp! It got her. I know it's warmer here? but I have already seen bees and a wasp or two! Martha had the pred and benedryl too. Could have been a stray bee that got O. Ahh, I remember the "mato pox!" No advice from me about the surgery-unless it's a real breathing problem........for her.
