well your right we do keep them in captivaty,(sorry spelling)
but there is nothing wrong we feeding live,providing you can have a staple suply through the rest of the snakes life,HOWEVER iI DONT FEED LIVE BECAUSE ITS EASIER TO FEED DEFROST,NOW THEN YOU HAVE THE CHOICE to feed live or dead
its no use getting upset because poor m or rat is being fed live or dead some snakes have to in order to keep them alive untill they can be got on to dead,
