>You simply clip a nail, collect the blood in a heperanized hemacrit tube I can't believe you said that Anne. That is EXTREMELY painful for the ferret and totally unthinkable. This is NOT the way to get blood from a ferret. You know from grooming accidents that it makes a ferret vocalize in pain, and as stoic as they are that's a horrid experience when they scream out.
