“With a meal like that, it would sit in a cave to digest for about a week and then not need to eat for four to six weeks.” (http://www.theguardian.com/environment/2014/dec/30/python-devours-entire-wallaby-in-front-of-northern-territory-park-rangers)

After that first week, a wee tipple would be welcome.
Happy Hogmanay.
