Ok in all honesty I didnt mean to offend you.... I was just stating my opinion
But anyways how big was the prey item? was it thick then the snakes widest point? some times snakes will not try to swollow unless the prey items heart has stopped. unless of course you fed it too big of a prey item that it couldnt kill. What do you mean by "contractions" some snakes will wiggle in order to help the food slide down.
and you right I didnt read it all.... I made a snap judgement And I will applogize for that and what i said
"Far more crime and child abuse has been committed by zealots in the name of God, Jesus and Mohammed than has ever been committed in the name of Satan. Many people don't like that statement, but few can argue with it."
