I Have heard the same studies as you Smokey.Also they just throw away the cords after the birth process so why not use them.
Beeniesmom, I do disagree it is the start of a baby. Whould you feel the same if it were kitten or pup "embros"? Not trying to start a fight just wondering . I know some folks here say no to aborting pets but yes to humans . I can't ever figure that thinking out. Some one what to try to explain it to me.
