I had a small group that THOROUGHLY enjoyed themselves with Thenford Grey's tour of St. Kitts. I highly recommend:
I don't know anything about drunken monkeys, but like Donna said, there were some rather tame monkeys at Turtle Beach, along with Wilbur the resident pig. I personally wouldn't feed an animal anything harmful, and didn't see anyone else do that at the time of my visit.
I loved St. Kitts!
