I've never seen rodent bites on a snake (mine have all switched over to f/t thankfully.) but they're not all in pairs. There are spots where there's just one off on it's own, and there is no redness/open wounds. He's a fat boy, about as fat as my 2 year old BP but about half a foot shorter.

They didn't use PAM, I told them about it and to look into it. I use it at home and always have some on hand. Have already treated his new home with it prior to putting him in. I treat my snake-enclosures monthly with PAM when I clean out the cages. (last time was about 2 weeks ago.)
