First a miss meal is no biggy it's a BP that's what they do second you will need to provide information to see if this is a tell tell sign of something that is likely to re-occur (fast) and that needs to be adjusted.
What is the size of your animal (weight)?
What is the size of your enclosure?
What are your temps (cool and warm side)?
How do you measure your temps (type of thermometer and where do you take your reading)?
What is your humidity?
What kind of hide do you have (are they tight)?
How often have you handle your BP?
What type of prey do you offer (Size and live or F/T)?
How do you offer it?
The more info the better.
