Sorry, but I kinda have to agree with Spencer. These are living animals. Not "oh it died, I'll just get another one." You blame the feeder size as the reason for death, but have not answered my question to you- if they were too big, WHY DID YOU NOT CUT THEM INTO SMALLER PIECES??? For the last few weeks I have not had mice small enough to feed my 15 gram babies, so I have been cutting up hoppers into thirds or halves depending on the size and feeding them.
Also, you KNOW regurges require special care, so the fact that you kept feeding your snake anyway, without the proper wait time, without a gut enhancer, and without tiny cut up easy to digest pieces is what ultimately resulted in the death of your snake(s). Just because you have an "empty" tank doesn't mean you should take on another life that will end up sick and dead because you are not taking responsibility for its care. If you really feel the need to "fill the tank" why not make a terrarium and fill it with Venus flytraps or other interesting plants??
