pretzelpretzel, you might want to start another thread asking for "HELP -possible PAM poisoning?", as others here (probably the mods) may have more info
to help you until you can see the vet, but from the title of this thread, most aren't realizing the issue to chime in. I know I remember others on forums having
toxic reactions in their snakes from using PAM...I'm not positive what else might be of help right now though, other than reducing any further contact he may
have & encourage him to drink water (to help flush out).
