Look at it like this. Your snake eats a small meal every 5 to 10 days. Some people will say 5 some 7 some 10. Lets agree for sake of argument and math, every 6. I say small because 10% to 15% or prey that is roughly the same girth as the snake is not the largest they are capable of eating. I am sure we can find some people to give us examples of BP's eating much larger. Lets further assume that people normally eat 3 meals a day. Yes I know some people eat more or less and are fine. So lets further assume that you go 6 hours between meals. So that's eating breakfast at 6pm, lunch at noon, and dinner at 6pm. That makes a day for a snake equivalent to about and hour in human time. I know that there are a lot of issues with this analogy but the conclusions you can draw are sound. What you are basically asking is equivalent to saying what will happen if you eat dinner an hour early, or an hour late. The answer is that these are only guidelines that you should try and follow. Your snake is going to be fine just like you would be fine if you went to bed without eating dinner. You might wake up hungrier than normal. It's totally understandable that you are concerned and all anyone can do is tell you that its ok and hope you feel better about it. I remember the first time my snake did a long fast I stopped worrying about missing a meal, or feeding a day late or a day early. My winter fast was particularly long this year but I read some posts on this forum and after hearing a person or two talk about a fast lasting a year or more I began to get some perspective. I have a yearling carpet python that I wouldn't want to go more than 7 days without offering a meal but before I got her, or once she is a little bigger, I wouldn't think twice about going on a 2 week vacation.
