Yeah it runs under it and up the side. The tstat I use doesn't store the highs and lows, but I had an accurite in the one next to his on the same tape and it didn't register that high in the last 24 hours, but I've read plenty of places that heat tape can be inconsistent. I just moved him from the freezer (he was only in there 30 minutes or so) and I'll call the vet about the necropsy tomorrow. I took a picture of his belly to see if this looks like a burn?
