I have read documented cases and have even seen pictures of ball python cannibalism. It's not pretty...

To the OP, if your friend has housed them together for this long and has been feeding them all separately, I don't think you'll have to worry about one snake eating another at this point. The general consensus is that it's a bad idea to keep multiple snakes in a single enclosure because of the POTENTIAL for stress and other problems. I'd take the previous posters' advice and try to politely direct them to this site and try to educate your friend, but do so in a manner where they don't feel personally attacked or made to feel "Wrong" for what they were likely told by someone else was perfectly acceptable.
