How many hatchling have you started? How many animals failing to thrive have you put back on track? You can disagree but when offered a first meal you will get a higher percentage of success (hatchling taking their first meal successfully first time offered) if that first meal is a mouse (that comes from someone that used to start everything on rats and no longer does)
Not to mention that the animal in this case when it was eating was eating mice so trying to switch is the last thing that needs to be done at this point it need to feed what it used to feed on and again mice are more enticing.
Do my snake prefer rats over mice? Yes they do but my snakes however are not the issue here.
