I do not have a scale at the moment but it has been on my to do list for awhile now honestly. I've never really seen the need for one because even though he has done this before it has never lasted this long and weight loss has never been an issue for me. I wish I had exact figures now, believe me.

Any recommendations on a particular scale or place to obtain one?

Thank you everyone for your help as well as your candor.  I might never forgive myself if I really just allowed myself to be persuaded to prolong my snake's hunger strike. If he goes long enough he can start to experience liver damage can't he?

What do you guys suggest about blood work or other tests which I'd be willing to bet this vet will try to sell me?
Also, can anyone recommend a different vet? I've taken Pythagoras there before but this was the first time they performed anything other than a physical exam. I live in Durham, NC.

Anyone think I have a halfway decent shot at a refund? At least for the force feeding?
