The only time you should stop feeding your Carpet Python or any snake for that matter is when you put the snake into brumation (hibernation) - which is a cooling period of anywhere from 4-6 weeks on up. Most people only brumate their snakes when they are going to breed them, as it is necessary for most species to breed, however if you are keeping the snake for your own pleasure with no plans on breeding the snake than IMHO there is no reasonn to cool him/her down. However don't be deturred if the snake refuses food during the winter months as sometimes it is their natural insticnt to not eat.
good luck!
