Nope it does not
I open the tub and the rat is snatched immidiately often in mid air without having the time to hit the enclosure ' floor. (That's what solid routine and pre-scenting does)
I also have no issue moving on to the next tub as rats are not those evil creatures that will attack a snake and gnowl on it for the next 5 to 10 min and kill it. (That's what a stress free well fed and hydrated rodent does, just sit in the corner) - All uneaten preys (rare occurance) are removed within 10 min)
Again never had an issue with and ut's not luck 1000's of owner do the same including big breeders, mist people just don't share their experience because for some it's a sensitive issue and they cannot debate it rationally.
I am not promoting live feeding I could not care less what people feed, I answer the questions on live feeding based on MY experience which people who call live feeding reckless and dangerous rarely have (it's based on hearsay and graphic pucture that do not reflect responsible live feeding)
Live is not for everyone but if someone is comtempling it they should get answers based on experience and decide for themselves.
For the record I also feed F/T (All colubrids are fed F/T mice )
