Re: Grrr, new carpet python not eating!!
I would not be concerned. Leave her a couple of weeks without handling and try again. If you do go for scenting just add some fluff from a day old chick on the mouses nose. The weight loss is not an issue either as that amount could easily be done through passing urates or stool.
On a comparative side my diamond pythons only feed for about six months of the year and do not lose any condition. A carpet of your size not having fed for a few weeks is no concern. There is a good chance that is because it is in unfamiliar conditions and also not accustomed to being handled. Also it's good you are giving although being the same prey type may smell different due to differing qualities of available frozen rodents.
