Every other week sounds good for not stressing the snake... but what about when the snake not eating is under a year old? My 9month old hasn't eaten in well over a month and has lost about 6 grams. I think it might have been due to two moves and the cold winter, so now she's back in her original home and has been left totally alone for a week. I'm going to try her tonight, in the cage, with a PK recently weaned mouse (maybe she's intimidated by the bigger ones), but if she still doesn't take... not sure what I can do but just keep offering and hope she takes one sometime soon.
And, due to current bad situation, I can't afford any vet visits right now.
