one missed meal is nothing to be worried about. even my good eaters refuse meals every once in a while. some reasons for random refusals could be ongoing shed cycle (it will eat after the shed), full stomach (it will eat after it poops), or no reason at all (it will feed on the next feeding day).
then there's the problematic eaters........they normally do not eat on schedule, once in a while they do...they seem ok though so i decided to stop worrying about them and just be glad when they eat, but not feak out when they are being themselves..
this happens despite ideal parameters, same rack housing several snakes but there's just those that do not behave like we expect them to.
